Novel biological deodorization system for sewage plant

Abstract

The invention discloses a novel biological deodorization system for a sewage plant. The system is respectively provided with an acid treatment unit, an alkali treatment unit, an adsorption treatment unit, a microbial treatment unit and an optical microwave treatment unit from bottom to top. The operating method comprises the following steps: sequentially performing acid treatment and alkali treatment on odor in the sewage plant so as to remove particles, alkaline matters and acidic materials; performing high-efficiency adsorption treatment on the odor by virtue of activated carbon, a lignite adsorbent and a functional fiber adsorbent; decomposing odor molecules in the odor by microbes by virtue of the microbial treatment unit; and finally, degrading organic matters in the odor into non-toxic and harmless small molecules by a UV tube and a laser tube in the optical microwave treatment unit. Meanwhile, a sterilizing effect is achieved. The novel biological deodorization system disclosedby the invention is simple in structure, effective, reasonable in design, convenient, practical and capable of performing complete advanced treatment on the odor in the sewage plant, ensuring up-to-standard discharge at the initial operating stage and improving the system treatment effect.

Description

technical field [0001] The invention relates to the technical field of urban sewage treatment, in particular to a novel biological deodorization system of a sewage plant. Background technique [0002] With the rapid development of social economy and the continuous acceleration of urbanization, the problem of environmental pollution has become increasingly prominent. In recent years, the stench produced during industrial manufacturing, garbage treatment, and sewage treatment has seriously plagued the lives of residents, especially the residents around sewage treatment plants and garbage treatment plants complained and suffered unspeakably. Odor emission standards are becoming increasingly stringent, and it is urgent to find a deep and thorough treatment process for odor. [0003] There are three main methods for controlling stench and waste gas from sewage plants: physical method, chemical method and biological method. Physicochemical methods such as absorption and adsorpti...

Problems solved by technology

[0004] However, in the actual application of this process, the water distribution is often uneven due to the large device, the air resistance is large due to the high packing layer, and the filter material is clogged due to excessive microbial growth, which leads to low treatment effect of the system and difficult operation and management. Therefore, it is provided A kind of structural design is simple, but effective sewage plant biological deodorization system is very necessary
