Standard grade of sewage treatment
The sewage treatment standards were divided into Level 1, Level 2, and Level 3. According to the Integrated Waste Water Discharging Standard, the first-class standard was applicable to the discharge of sewage into Class III water areas (except for designated protected areas and swimming areas) and Class II sea areas in Class B. The Level 2 standard is applicable to the discharge of sewage into Class IV and V waters in the standard of the national standard 3838 and Class III sea areas in the standard of the national standard 3097. The Level 3 standard was applicable to the situation where the sewage was discharged into the urban drainage system with a secondary sewage treatment plant. The specific standard values and requirements may vary by region and industry.
Personal work summary of sewage treatment
We can come to the following conclusion: The personal work summary of sewage treatment is a document that sums up an individual's performance and achievements in sewage treatment work. According to the document provided, the contents of the personal work summary included learning and improving work ability, paying attention to theoretical study, striving to improve their own quality, earnestly performing their duties, completing work tasks, and abiding by rules and regulations.

Function of Denitifying bacteria in sewage treatment
Denitifying bacteria played a very important role in sewage treatment. It can gradually reduce NO2 to NO2, NO, N2O, and N2, thereby achieving the purpose of nitrogen removal. In the A/O process (the anaerobic process), the sewage was nitrated in the aerobic pool to produce nitrates. The nitrates entered the anoxic-deficient pool, and the heterotroph anaerobic detoxifying bacteria used organic carbon sources as electron donators, replacing molecular oxygen with nitrates as electron receptors to carry out anaerobic breathing. While decomposing organic matter, nitrates were reduced to nitrogen, thus achieving biological nitrogen removal. In hospital sewage treatment, the detoxifying bacteria could effectively remove the total nitrogen in the sewage and reduce the environmental pollution caused by nitrogen. As for the Aerobic Denitfying bacteria, it could complete both the nitration and the detoxification in the Aerobic pool. On one hand, the products of the nitration could directly become the matrixes of the detoxification reaction, so as to avoid the inhibition of the accumulation of NO2-, and accelerate the nitration reaction process. On the other hand, the Oh ~ 2 produced by the detoxification could partially compensate for the alkalium consumed by the nitration reaction and maintain the stability of the system's pH. Moreover, the nitration and the detoxification were carried out under the same conditions and in the same system, which could simplify the operation difficulty and greatly reduce the investment cost and operation cost. The autotrophs did not need organic matter as a carbon source. Only the presence of mineral salt could complete the detoxification process. When sulfur or sulfur was oxided to sulfuric acid, nitrates were reduced to nitrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Top ten brands of sewage treatment equipment
The top ten brands of sewage treatment equipment included Jindalai, Pengkai, Lingyun, Tianyu, Kaiyuan, Nanfang Zhishui, Lanshen, De 'an, Qingyuan, and Tongyu.

How much is the sewage treatment fee in the community?
The price per ton of sewage treatment fees in the community is uncertain, because different areas and different property companies have different charging standards. The sewage treatment fees of the cities mentioned in the search results were 0.95 yuan per cubic meter, 1.35 yuan per cubic meter, 2.10 yuan per cubic meter, and 3.60 yuan per cubic meter. However, there was no mention of the specific cost of sewage treatment in the community. Therefore, based on the information provided, it was impossible to accurately answer the cost of sewage treatment in the community.
What are the requirements for rural sewage treatment and maintenance?
The requirements for rural sewage treatment maintenance mainly include the following aspects: **1. Pump maintenance** - Regularly check, adjust or replace the inlet and outlet gate valves of the pump. - Regularly check the water gauge of the lifting pool and its conversion device facilities. - To ensure that the standby pump can work normally, generally conduct a trial run once a month. - When the temperature is lower than 0 °C, drain the water in the pump shell in time. **2. Fan maintenance** - Fans without oil or lacking oil are prohibited from running. Check the lubricating oil situation before starting the machine. - Do a good job of regular inspection. Once abnormal conditions are found, stop the machine in time and conduct a detailed inspection. - Check the lubricating oil of each bearing and the water - cooled and air - cooled pipelines, and generally overhaul once every three months. **3. Dosing equipment maintenance** - The dosing equipment involved should also be checked accordingly. Regularly clean up the sundries in the dosing tank. - Regularly check the lubrication of the stirrer and metering pump, and the general overhaul interval is also three months. **4. Grid slag removal** - Remove grid slag according to the specified time. During the flood season, the number of decontamination must be increased to ensure the smooth flow of water. - When the grid decontamination machine is in working state, if a fault is detected by the monitoring equipment, it must be stopped immediately for repair. **5. Inlet and outlet area equipment maintenance** - Generally, the mechanical seal and lubricating oil of the water pump are checked and adjusted every six months. - Regularly check the floating ball liquid level gauge in the sump and its conversion device, and do a good job of maintenance. **6. Aerated grit chamber maintenance** - Adjust the limit device of the sand suction machine once a month. - Ensure the smooth operation of the sand discharge pipe, drainage ditch and sand - water separator. - Keep the grit chamber, related equipment and relevant parts clean. In addition, for centrifugal fans in rural sewage treatment equipment, do not overload them. The lubrication of all parts should meet the requirements, and pay attention to the quality and replacement frequency of the grease. Regularly or on time listen to whether the centrifugal fan has a normal sound. If there is an internal impact or friction situation, stop the rural sewage treatment equipment first and check whether the rolling bearing or transmission gear is damaged or displaced. Keep the position of the centrifugal fan's rolling bearing foundation unchanged. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
