Domestic sewage treatment device and method for treating sewage by utilizing same

Abstract

The invention provides a domestic sewage treatment device and a method for treating sewage by utilizing the same. The domestic sewage treatment device comprises a trickling filter, a buffer water inlet pool, a microbial aerosol spraying pool and a water outlet pool, wherein the top of the trickling filter is provided with a water distributor; a filter layer is disposed in the trickling filter; thebottom of the trickling filter is communicated with the buffer water inlet pool; a sewage lifting pump is disposed in the buffer water inlet pool; a partition plate with holes is disposed at the bottom of the microbial aerosol spraying pool; atomizing spraying heads connected with the sewage lifting pump and used for spraying atomized water are disposed on the partition plate; the water outlet pool is communicated with the lower part of the partition plate; bacteria embedding bags and algae embedding bags as well as full-spectrum plant growth lamps and flushing devices are disposed in the inner cavity of the microbial aerosol spraying pool; a disinfecting device and a reflux device connected with the buffer water inlet pool are disposed in the water outlet pool; and a water outlet is formed in the side of the water outlet pool. The domestic sewage treatment device provided by the invention is high in treatment efficiency, good in filtering effect, low in cost and long in service life,can effectively kill pathogens and bacteria, and can perform chlorine removal.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a domestic sewage treatment device and a method for treating sewage with the device. Background technique [0002] The current sewage treatment method is to centrally supply the domestic sewage of each household to the sewage treatment plant through the pipe network, use the activated sludge method for centralized treatment, and then discharge it into the water body. Although this method can reliably and effectively manage and control sewage treatment plants, it also has many disadvantages: the activated sludge method cannot get rid of the shortcomings of cumbersome maintenance, large amount of sludge, and difficulty in realizing the utilization of tail water resources; As for the cost, the infrastructure cost of the pipeline often accounts for about half of the total construction cost of the sewage treatment plant; as for the maintenance, since most of the pipelines are ...
