Abstract

The invention relates to the field of sewage treatment, and discloses a distributed integrated domestic sewage treatment device and a treatment method, including a water inlet pipe (13), an aeration device (14) and a casing (1). The inside of the casing (1) is composed of a first The porous partition (5) and the second porous partition (6) are separated into an anaerobic reaction chamber (2), an aerobic reaction chamber (3) and a constructed wetland chamber (4), and in the anaerobic reaction chamber (2) There is a perforated water distribution pipe (7), the water inlet pipe (13) is connected to the perforated water distribution pipe (7), the anaerobic reaction chamber (2) is filled with anaerobic filler (9); the aerobic reaction chamber (3) is provided with The aeration pipe (8), the aeration pipe (8) is connected with the aeration device (14), the aerobic reaction chamber (3) is filled with foam blocks (10); the constructed wetland chamber (4) is filled with planting substrates (11 ), the planting substrate (11) is planted with aquatic plants (12). The invention has the advantages of compact structure, low equipment and operating costs, and obvious treatment effect.

Description

technical field [0001] The invention relates to a sewage treatment device and a treatment method, in particular to a decentralized integrated domestic sewage treatment device and a treatment method. Background technique [0002] With the rapid development of economy and the acceleration of urbanization process, my country's water environment has been seriously polluted. The current sewage treatment facilities are mainly urban sewage treatment plants. The scattered residential areas in rural areas are far away from urban areas, and the domestic sewage generated by them is difficult to connect to the urban sewage pipe network; this part of the sewage pipe network is difficult to collect or centrally treat uneconomical domestic sewage Collectively referred to as distributed domestic sewage. [0003] Distributed domestic sewage mainly refers to feces and flushing water, bathing sewage and catering sewage produced by residents in the production or living process, and also includ...
