Embodiment Construction

[0024] With reference to the process flow diagram of the present invention of Fig. 1, the sewage treatment flow process of the embodiment of the present invention is:

[0025] (1) The sewage enters the grit chamber through the lifting pump station, and is removed after the sediment and suspended particles are settled;

[0026] (2) pressurize with a booster pump and enter the primary aerated biofilm reaction tank with fillers from the bottom;

[0027] (3) Enter the secondary aerated biofilm reaction tank with fillers from the upper outlet of the first-level aerated biofilm reaction tank;

[0028] (4) Enter the quartz sand filter from the upper outlet of the secondary aerated biofilm reaction tank;

[0029] (5) Enter the upper part of the activated carbon filter from the bottom of the quartz sand filter through the U-shaped tube;

[0030] (6) Flow through the disinfection system;

[0031] (7) The flow to the middle water pool is completed;

[0032] In the process, a blower i...

Abstract

This invention relates to a process technology for resourcedizing life sewage, in which, a sewage pump lifts sewage to a sand deposition basin for eliminating sand and suspending particles, a first and second level aeration bio-film reaction basin realizes degradation of organic materials and nitration of ammonia nitrogen and reduces mud by optimizing the growing period and environment of microbes, a quartz sand filter basin eliminates suspended substances in the second level aeration biofilm reaction basin, an active carbon filter eliminates perculiar smell and chroma so as to reduce concentration of organics and suspended materials, a disinfection system system controls target of microbes and a mid-water basin stores the processed mid-water, which integrates the first and second levels of aeration bio-film reaction basin, the quartz sand filter basin and an active carbon basin to reduce occupied areas.

Description

technical field [0001] The invention belongs to sewage treatment technology, in particular to a domestic sewage resource treatment process with zero discharge of biological sludge. The invention also relates to a treatment device using the process. Background technique [0002] In recent years, with the increase of population and the rapid development of economy and society, the shortage of water resources has become the main problem seriously hindering economic development in many areas, directly affecting the sustainable development of my country's economy and society. The recycling of sewage is an effective way to alleviate the crisis of water resources. At present, the methods of recycling sewage can be roughly divided into three categories: biological method, physical chemical method and membrane method. Biological treatment is a generally recognized low-cost sewage treatment technology, but the common limitation of biological methods is the generation of excess sludge...
