Integral sewage disposal process for strengthening sludge filtrating technology

Abstract

The invention provides an integrated sewage treatment method of an enhanced sludge filtration technology, which combines the filtering of an anoxic reaction zone, an aerobic reaction zone and an upward flow sludge bed, has simple process flow, and can resist impact load. More particularly, the integrated sewage treatment method changes the traditional method of separating sludge from water and has more efficient separation of sludge and water as well as excellent quality of yielding water; further, the integrated sewage treatment method can effect the serialized and modularized production. The integrated sewage treatment method of the invention is a novel activated sludge treatment method, creates innovation on a process flow and a sludge and water separation zone, combines an anoxic selection tank, the aerobic reaction zone and the upward flow sludge filter tank as a whole and is characterized by flexible operation mode, high efficient separation of sludge and water and versatility and serialization of equipment.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to an integrated sewage treatment method that strengthens sludge filtration technology. technical background [0002] The pollution of domestic sewage and industrial wastewater produced by the continuous acceleration of urbanization is becoming more and more serious. It is characterized by small batches, wide dispersion, large changes in water quality, difficult collection, and the need for local treatment before discharge. The national "Tenth Five-Year Plan" proposes that the sewage treatment business of each province should combine centralized treatment with decentralized treatment in light of the economic status of the province. While vigorously developing urban centralized sewage treatment plants, develop economical and efficient nitrogen and phosphorus removal as soon as possible. Functional decentralized sewage (wastewater) water treatment system. In recent years, my country's hou...

AI Technical Summary

Problems solved by technology

However, at present, comprehensive domestic research on integrated sewage treatment methods and their facility processes, the most widely used are various buried combined small-scale activated sludge processes and biofilm processes, which are just a simple combination of various conventional processes. Existing processes Complicated process, high infrastructure and operating costs, narrow range of adaptability to water quality, unsatisfactory removal of nitrogen and phosphorus, etc.
