Novel FPM (Filterable Particulate Matter) integrated rural sewage treatment device

Abstract

The invention discloses a novel FPM (Filterable Particulate Matter) integrated rural sewage treatment device, and belongs to the field of water treatment. The device has a columnar structure, and comprises a fourth-order light quantum water channel, a first-order reaction zone, a second-order reaction zone and a third-order reaction zone in sequence from outside to inside, wherein the first-orderreaction zone is an annular oxidation channel which is mainly used for performing a nitrification-denitrification process; a first-order clarification zone is arranged in the annular oxidation channel; properly-clarified effluent enters the second-order reaction zone; the second-order reaction zone is used for performing mobile suspension bed biological activated sludge treatment and secondary denitrification, and lowering the organic load of subsequent deep bed filtration treatment; sewage enters the third-order reaction zone, and the reaction zone is a deep bed interception zone; third-orderdeep bed intercepted effluent is introduced into the fourth-order light quantum water channel on the outermost circle of a main body, and the sewage is deeply disinfected in the fourth-order light quantum water channel. For rural sewage with high ammonia nitrogen content, the integrated device has the advantages of small occupation area, short running period, no secondary pollution, easiness in construction and installation, convenience in automatic operation, and capability of efficiently removing ammonia nitrogen and organic matters.

Description

technical field [0001] The invention discloses a novel FPM integrated rural sewage treatment device, which belongs to the field of water treatment. Background technique [0002] There are many kinds of domestic rural sewage treatment technologies, such as commonly used physical and chemical treatment, anaerobic digester treatment technology and oxidation pond treatment technology. Anaerobic digester treatment technology can ferment the organic matter in sewage to produce biogas, and then remove most of the organic matter; biogas can be used as energy, and the fermented sewage can be used as irrigation water after proper treatment. However, this technology is greatly affected by temperature, and its application range is limited to a certain extent. In addition, the treated effluent needs further treatment before it can be discharged up to the standard. However, the oxidation pond treatment technology occupies a large area, has a slow reaction speed, and has problems such as ...

Problems solved by technology

[0004] Due to the development of rural industrialization, the rural water environment is deteriorating day by day, a large amount of industrial wastewater is included in rural sewage, and simple treatment processes cannot meet the requirements

Secondly, the proportion of rural areas in our country is relatively large, and the investment in using a large number of large-scale sewage treatment equipment is too large, which does not meet the conditions for rural construction in our country. Therefore, there is an urgent need for an integrated process that meets the current rural sewage treatment process, that is, an integrated process with a small footprint
