Waste Water Treatment
I recommend a few novels to you. 'My Fish Pond Became the Pollution Outfall of the Immortal World' was super interesting. The author was super light. In order to save the cost of immortal energy, the immortal world had to waste water. Zhu Renming's fish pond had become the sewage outlet of the immortal world on Earth. Chang'e's bathwater, Kitchen God's kitchen sewage, and so on were all discharged into it. Some people had read nearly 300 chapters and saved them to fatten themselves up. The author of " Dark New Era " loved spicy food. This was a fantasy novel. It was about a soul who had transmigrated to the dark world of the Shelter and wanted to change his fate to save a kind person. There was also detailed information about the character. The overall evaluation was that it was a dark work that could be seen. The Future Mother System of the Apocalypse, written by Yue Ziyi. The water flow meter was scammed by the Holy Mother System. After the apocalypse, it was still scammed into a five-year-old loli and thrown into a garbage city. However, the female protagonist was a genius, but she was a little scammed. " Curse of the Water Corpse Tomb " was a modern romance novel written by Ming Mo. The absurd sacrifice in the water-deficient villa, the unwillingness of the dead bride to remain silent, and the story after the curse broke out was very mysterious. 'King: From the Tauren's Cultivation,' I wrote it as a university student. In the fantasy world, there were many races and armies. The main characters were decisive and intelligent, but there were also shortcomings such as lack of writing. However, it was still worth watching. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction tank for waste water treatment
There are many types of reaction tanks used in waste water treatment. The following are some common ones: 1. * * Anerobic reactor (such as UASB reactor, anerobic tank)** - * * UASB reactor **: Commonly used in the treatment of microorganisms, it is a device that uses the decomposition of organic matter by the use of microorganisms. For example, in a chemical waste water treatment system, a "UASB reactor + multi-stage contact oxidization tank" was used for biological treatment. The concentration of the incoming water was more than 8000 milligrams per liter, and the concentration of the discharged water was stably lower than 300 milligrams per liter. It had a very high removal rate of COD. Moreover, the operation was simple, stable, and the treatment cost was low. - [** Anerobic Tank (Model ic)**: This is a high-efficiency multi-stage internal circulation anerobic reaction tank.] It has the characteristics of small area, high organic load, stronger impact resistance, more stable performance, and simpler operation and management. It is suitable for the treatment of organic high-concentration waste water, such as corn starch waste water, lemon acid waste water, beer waste water, potato processing waste water, alcohol waste water, etc. The water loading rate of the UASB reactor was much higher than that of the ordinary UASB reactor, and it was generally about three times higher. When it was used to treat high-concentration organic waste water with a chemical oxygen demand of 10000 - 15000 g/1, the volume loading rate could reach 15 - 30 kg-COD3. Because it has achieved its own internal circulation (The circulation volume can reach 10 - 20 times of the incoming water), reducing the concentration of organic matter at the bottom of the reaction tank and improving the impact load resistance. The large amount of water also makes the sludge at the bottom expand, ensuring the full contact reaction between the organic matter and microorganisms in the waste water and increasing the treatment load. It is equivalent to the serial operation of the upper and lower UASB reaction tanks. The lower reaction tank plays the role of "rough" treatment, and the upper reaction tank plays the role of "fine" treatment, so that the water quality is good and stable. 2. * * Chromium-breaking reaction tank **: In the plating waste water treatment process, the chromium-plating waste water is added with acid and Na2SiO2 to reduce the chromium-breaking reaction tank. Under acidic conditions, the oxido-reduction reaction between the hexa-valent chromate and the reducing agent occurs, and the hexa-valent chromate is reduced to tri-valent chromate, which then enters the neutralizing reaction tank. 3. * * Neutralization reaction tank **: A reaction tank used to neutralize the reaction water, nickel-plated and copper waste water, and add alkali-based solutions in the plating waste water treatment process. Trivalent Chromium-Copper Ion and Ni-Metal Ion would produce fine particles of Metal Hydride under the Alkaline Condition, which would form clusters under the action of the flocculating agent to accelerate the settling and reduce the settling time. 4. * * Electrolyser **: In the secondary treatment process of the plating waste water treatment process, it is mainly used for the waste water after the coagulated settling treatment to be subjected to the electrolyser. Iron filings were used as the positive pole, carbon particles were used as the negative pole, and waste water was used as the solution to form a tiny primitive battery. Under the conditions of acidic medium and oxygen, an electrochemistry reaction occurs, producing new ecological hydrogen and iron. The new ecological hydrogen and iron could react with the oxido-reduction reaction of hexa-valent chromate and complex in water to produce iron trioxides, which had a high flocculating effect and could absorb and disperse tiny particles and organic molecules. After the electrolysation, the waste water was further coagulated and settled before entering advanced treatment. 5. * * Comprehensive filter device (can be seen as a form of reaction tank)**: It is used in the tertiary treatment of the plating waste water treatment process. Its main components include quarts sand, activated carbon, silica gel, etc. It can completely filter out the floccule precipitations and precipitations in the solution to achieve a higher filtering effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Waste Water Treatment Pit, Anerobic Pond, Reaction Pond
The reactor was a common reaction tank structure in sewage treatment. It used the efficient effect of the anaerobia to remove the organic matter in the waste water, but in this process, the pH value needed to be adjusted appropriately, and the operation control was more complicated. Even so, the digesting tank could remove most of the chemical oxygen demand (Biochemical oxygen demand). In the overall process of sewage treatment, the biochemical tank played an important role. It cooperated with other reaction tanks such as the acidotic tank, the anoxic-deficient tank, and the Aerobic tank to complete the deep purification of sewage. For example, the acidification pool could transform the big molecular organic compound in the sewage into small molecular organic compound that was easy to be biodegraded, which could improve the biochemistry of the sewage and lay the foundation for the treatment of sewage in the anoxia pool. The main function of the anoxia pool was to realize the detoxification, remove the nitrate-nitrogen in the sewage, and at the same time, remove part of the biochemical oxygen demand. Aerobic tanks ensured that the dissolved oxygen content in the water was stabilized at about 4 milligrams per liter by means of aerating, so as to promote the growth and reproduction of airborne microorganisms, thereby effectively removing all kinds of polluting substances in the sewage. The entire sewage treatment process was a highly integrated and interconnected system, and every part was indispensable. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Rebirth Waste Treatment Plant
He recommended a few novels. << REBIRTH 1978 >> could be a big or small creation. It was about urban life. The main character was reborn at the beginning of the reform and opening up, starting a different and exciting life. The female lead was alone and the female lead was often a bystander. " Rebirth: I was a mobile vendor in the apocalypse " was written by the short-legged No. 8. It was a sci-fi apocalypse genre. Before Wang Xiaoxiao was reincarnated to the day she was bitten to death by zombies, she was still bound to the apocalypse vendor system. " The New Age of Darkness " was a fantasy-type novel that loved spicy food. A transmigrator would descend into the Dark Land to change his fate. There was also a lot of information about the characters. It was rated as a dark novel that could be watched. " Rebirth of the Purified Space " was a creation of cute meat and eggs. It was a Xianxia story. Xiao Yan was reborn into the Purified Space, and her environmental protection career flourished. " Transdimensional Trash Station " was written by Xiao Cheng Gu Dao. It was an urban supernatural ability. The protagonist Su Jing's backyard became a transdimensional trash station, and the trash from multiple spaces became the treasure of his fortune. The creativity was good. Although it collapsed a little in the later stages, it was not bad overall. It was worth watching. The novel " I Transmigrated and Became the Queen of Starry Universe " is equally exciting. Everyone is welcome to click and read it!
