Elementary Design of Water and Waste Treatment in the Nurseries
The following are the preliminary design opinions of the kindergarten water supply and drainage profession: ** 1. Water supply system ** 1. ** Pressure and comfort ** - The kindergarten is generally a multi-storey building, and the water supply pressure should be less than 0.35MP. From the perspective of comfort, the water supply pressure of each floor should be about 0.20MP. 2. ** Water Purification Equipment ** - With the concern for the health of drinking water, qualified kindergarten could consider using a direct drinking water system. Most of the household school direct drinking water purification equipment used reverse infiltration equipment, which had the advantages of ready-made drinking water, health and safety, saving money, convenience, and no need to worry about dirt residue and harmful components in the water. 3. ** Water consumption calculation ** - Various water consumption standards, water consumption units, working hours, hour variation coefficient, maximum daily water consumption, maximum hour water consumption, etc. shall be stated or listed in a table. 4. ** Water supply method ** - If the water pressure and water volume of the external network can often meet the water requirements, and there is no special requirement for indoor water supply (such as single-story or multi-story buildings), the direct water supply method can be used, which is directly connected to the external water supply network, and the external network water pressure is used for water supply. However, when the external network pressure exceeds the permitted value, a pressure reduction device should be installed. - If the external network pressure is periodically insufficient and the indoor water pressure is required to be stable (multi-story building), the water supply method of setting up a water tank can be used, which is directly connected to the external water supply network to use the external network pressure to supply water. At the same time, a high-level water tank is set up to adjust the flow and pressure. - If the pressure of the external network is often or intermittently insufficient, the external network allows direct pumping (multi-story building), and the water supply method of water pump and water tank can be used. The water pump directly draws water from the external network to increase pressure and uses the high-level water tank to adjust the flow. When the external network pressure is high, it can also directly supply water. If the municipal department does not allow direct pumping, it is necessary to add a pool to draw water from the pool. ** 2. Hot Water System ** 1. ** Heat Source Selection ** - In terms of heat sources, it could be divided into electric energy, gas, solar energy, and air heat. - The electric water heater includes the storage-type and the instant-heating type. The storage-type electric water heater is large in size, the water storage tank takes up space and needs to be pre-heated. The instant-heating electric water heater has high power, high requirements for the circuit, and high manufacturing costs for hot water. - The initial investment of the gas water heater was low, the thermal efficiency was high, the heating speed was fast, and the water temperature was constant. However, it produced waste gas and was dangerous, so it was not suitable to be installed in the kindergarten building. - The solar water heater had a clean energy source and low cost of producing hot water, but it was greatly affected by the weather and needed an auxiliary heat source. - The air-source heat pump water heater had a clean energy source, low cost of hot water production, and was not affected by the weather, but it was not suitable for use in cold areas. The kindergarten should choose the heat source based on the actual situation. 2. ** Hot water supply method ** - Considering that there was a holiday period in the kindergarten and the number of children was small, it was appropriate to use a distributed hot water supply. Water heater was set up near the hot water point. The pipe network was short, the heat loss was small, and the reconstruction and expansion were more convenient. Although there were disadvantages such as inconvenient management, occupying more total building area and higher total equipment cost, it was convenient for the operation and management of the kindergarten to avoid unnecessary energy waste. 3. ** Hot water temperature ** - The hot water temperature of the kindergarten shower was 35 degrees, and the water temperature of the sink faucet was 30 degrees. The hot water temperature supplied by the water heater should be higher than these two temperatures. A constant temperature water mixing valve should be set to ensure that the water temperature of the faucet was constant, not affected by the change of water temperature, flow rate, and water pressure. When the cold water was interrupted, the hot water could be automatically turned off to play a safety protection role. - The kindergarten should be equipped with a water boiler. The location of the water boiler should be close to the teacher's office and there should be measures to prevent children from entering by mistake to prevent burns. ** 3. Water drainage system ** 1. ** Diagram of drainage pipes ** - It should not be placed above the non-staple food operation and cooking in the canteen and the food industry. It should not be placed above the medical health care room and the dining area of the classroom. When the conditions cannot be avoided, protective measures should be taken. - The location of the drainage pipe should not be close to the outer wall of the dormitory. ** 4. Fire Protection System ** 1. ** Fire Hydrant System and Automatic Sprint System ** - The design of the fire extinguisher system and the automatic sprinkling system should be carried out, and the design basis, design parameters, water supply method, equipment selection and control method should be specified. ** 5. Design basis and scope ** 1. ** Based on ** - The contents related to the design of this discipline in the approval documents and basis data listed in the general design description shall be extracted to clarify the main regulations and standards adopted by this project, as well as the design data of this project provided by other disciplines and the municipal conditions available for the project. 2. ** Range ** - According to the design task book and relevant design information, explain the design content and division of labor of the specialty (when there are other units to design together).

How do the three of them work together to open a kindergarten?
There were many ways for the three of them to split the work in a kindergarten: 1. ** Division of labor according to the amount of investment **: The partner with more investment can be in charge of the work of important departments such as finance. For example, in terms of financial work, one needed to have strong capital management ability and financial knowledge. If a partner invested more, he could be responsible for the overall financial revenue and expenditure, budget preparation, financial statement analysis, etc. 2. ** Division of labor by function ** - ** Overall and Financial Work **: You can arrange a partner to be responsible for overall and financial work, including the development of the kindergarten's development strategy, management system, financial revenue and expenditure management, etc. This required the partner to have strong comprehensive management skills, financial knowledge, and the ability to control the overall operation of the kindergarten. - ** Daily Life and Purchasing Work **: Arrange a partner to be responsible for daily life management and purchasing work. Daily life management covered the daily life of children, activities, etc., and the purchasing work included the purchase of teaching supplies, daily necessities, and other materials. The partner in charge of the job needed to understand the living needs of young children, the market supply situation, and have certain negotiation skills and cost control awareness. - ** Teaching Management **: The third partner can be responsible for teaching management, such as developing teaching plans, managing the teaching team, evaluating teaching quality, etc. This required the partner to understand the teaching methods and curriculum of early childhood education, and have a certain educational background or experience in the education industry. 3. ** Division of labor based on resource advantages ** - If there were people among the partners who were good at communicating and coordinating with government departments and all walks of life, they could be responsible for external communication, handling relevant approval procedures, and striving for policy support. - If a partner has an advantage in terms of educational resources (such as connections with education experts and well-known schools), they can be responsible for introducing high-quality educational resources to improve the educational level of the kindergarten. 4. ** refer to the division of labor in similar institutions **: refer to the division of labor in other successful kindergarten or nursery schools. For example, in the day-long process of the nursery, the division of labor among the three students in the class could be referred to as: - ** The toilet segment **: It is easy to be chaotic when the location changes, and it requires reasonable positioning. For example, one partner would stand between the classroom and the toilet to organize the babies, one would stand where the hand towels were placed, and the other would stand near the sink. - ** Lunch segment **: Three people eat together, and then divide the work according to the baby's eating situation. For example, one partner would take care of the infants who had finished eating, one would take care of the infants who had not finished eating, and the nursery would clean up the appearance of the infants. - ** Napping session **: Nurses are responsible for the washroom, teachers in the assigned class make milk powder, and teachers in the main class pay attention to most of the infants. Each person is responsible for a portion of the infants when accompanying them to sleep. Nurses carry out hygiene work after most of the infants fall asleep, and implement a 15-minute inspection system after all the infants fall asleep. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
