Problems solved by technology

[0005] Second, in the process of sewage and sludge treatment, when anaerobic treatment is carried out for a long time, sulfur-based odor substances will be produced
The post-processing deodorization process is mainly to collect and deodorize the source of odor emission. For example, the dehydration machine room can only carry out negative pressure to keep the odor in the dehydration machine room for collection and removal, but the staff need to enter to work. Gas can directly affect the staff; another example is that the dehydrated mud cake needs to be transported outside. Distributed by the delivery vehicle to wherever it passes

Abstract

The invention provides a sewage / wastewater root deodorization treatment device, which comprises a biological reaction device and a sludge reflux device connected with the biological reaction device, the biological reaction device at least comprises an aerobic reaction device, and also comprises one or two of an anaerobic reaction device and an anoxic reaction device; and the biological reaction device also comprises a microbial culture device which is arranged in the aerobic reaction device and / or the anoxic reaction device, and a composite filler for culturing deodorization microorganisms is arranged in the microbial culture device. The invention also provides a sewage / wastewater root deodorization treatment process. The method comprises the following steps: filling a composite filler for culturing deodorizing microorganisms into a microorganism culture device, then arranging the microorganism culture device in an anoxic treatment device and / or an aerobic treatment device, inducing and culturing the deodorizing microorganisms in raw water in an aerobic environment, and enabling each unit to be filled with the deodorizing microorganisms along with the backflow of sludge to remove odorous substances; therefore, the deodorization effect of the whole system process is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage / wastewater deodorization treatment, in particular to a pollution / wastewater source deodorization treatment process and device. Background technique [0002] Sewage / wastewater treatment plants produce a lot of odor. The main structures that generate odor include sludge pump room, grille, grit chamber, biological reaction tank anaerobic tank, sludge concentration tank, sludge storage tank, sludge Dehydration room, etc., will bring harm to the health of staff and surrounding residents. The nasty odor can cause loss of appetite, dizziness, nausea, vomiting and mental disturbance. In severe cases, the odor can also damage the public's self-esteem, affect people's communication, and make people more concerned about sewage treatment. Facilities look otherwise, reducing the investment value of land in surrounding areas, leading to market decline. Moreover, due to the high content of hydrogen sulfide in s...
