Integrated wastewater treatment equipment for rural, scenic, lodging and other domestic sewage treatment plays an important role in some projects, although the water quality standards, but the odor is unacceptable. Sewage odor causes:
1, integrated wastewater treatment equipment, most of the process of biological treatment process, accelerating the growth and reproduction of microorganisms, but the activities of these microorganisms also increase the generation of odor. Biological treatment method of equipment requires continuous aeration, once the equipment is less airtight, naturally there will be odor overflow.
2, domestic sewage mixed with feces and a lot of debris, so the original smell is more unpleasant, in the case of higher temperatures in the summer, the domestic sewage treatment equipment to increase the production of odor, sulfate in the anaerobic bacteria under the action of the reduction into hydrogen sulfide produced by the odor.
