With the development of rural economy and the increase of population, the discharge of rural domestic sewage is also increasing. In order to protect the rural environment and people’s health, more sewage treatment facilities need to be built to treat rural domestic sewage. Township sewage plant integrated equipment has emerged at the historic moment, that its work process exactly how, today to understand.
The integrated equipment of township sewage treatment plant mainly uses AO biological treatment process to remove organic pollutants and ammonia nitrogen. Its working principle is in class A, because of the high concentration of organic matter in sewage, microorganisms are in a state of hypoxia, at this time, microorganisms are facultative microorganisms, they will decompose the organic nitrogen in sewage into NH?-N, while using an organic carbon source as an electron donor, the NO?-N、NO?-N is converted to N? And using some of the organic carbon sources and NH?-N for the synthesis of the new cellular material.
Therefore, the class A pool of the integrated sewage treatment equipment not only has A certain organic removal function, reduce the organic load of the subsequent aerobic tank, which is conducive to nitrification, but also rely on the high concentration of organic matter existing in the raw water to complete denitrification, and finally eliminate the nitrogen eutrophic pollution.
In the O class, because the concentration of organic matter has been greatly reduced, but the integrated sewage treatment equipment still has a certain amount of organic matter and high NH?-N exist. In order to make further oxidation decomposition of organic matter, and under the completion of carbonization, the nitrification energy proceeds smoothly, the aerobic biological contact oxidation tank with low organic load is set at the O level.
Aerobic microorganisms and self-oxygenic bacteria mainly exist in the class O-pool of the integrated sewage treatment equipment. Do aerobic microorganisms decompose organic matter into CO? And H? O, Inorganic carbon or CO in air? As a nutrient source, will the NO in the sewage?-N、NO?-N turn into N?. The effluent of the O pool flows to the A pool, providing the electron receiver for the A pool, and finally eliminating the nitrogen pollution through denitrification.
The integrated equipment of the township sewage treatment plants in different regions needs to choose the suitable sewage treatment technology according to the specific situation of the rural areas, and also needs to consider the feasibility, economy and environmental impact of the technology. Jiading environmental protection integrated sewage treatment equipment can meet the needs of 0.3-combined 10,000 tons of sewage treatment, and 9 series of products can be selected freely, according to different scenarios.
