Embodiment Construction

[0017] The present invention is further described below by embodiment, but protection scope is not limited by these embodiments.

[0018] The domestic sewage first passes through the grid or grid to remove solid waste such as plastic bags and cloth strips, and then enters the primary sedimentation tank for inorganic matter to stand still (that is, the sedimentation method). The bottom of the primary sedimentation tank for inorganic matter. The effluent from the inorganic matter primary sedimentation tank enters the hydrolysis regulating tank, and the hydrolysis regulating tank collects all kinds of sewage to make it fully mixed, and stays for 6-8 hours to ensure the stability of the effluent water quality. The sewage is regularly and quantitatively sent from the hydrolysis adjustment tank to the microbial media oxidizer through the lift pump for oxidation, phosphorus and nitrogen removal. And penicillium and other microbial media filler interception, adsorption, decomposition...

Abstract

The invention discloses a thermal insulation biological medium oxidation treatment method for domestic sewage. The thermal insulation biological medium oxidation treatment method for domestic sewage comprises the following steps of: (1) removing solid impurities in the domestic sewage; (2) carrying out oxidation and nitrogen and phosphorus removal treatment on the domestic sewage treated by the step (1) by virtue of microorganism medium, so as to remove organic matters; and (3) feeding the domestic sewage treated by the step (2) into a denitrification tank added with a carbon source to be denitrified, wherein temperature of the microorganism medium in the step (2) is maintained to be 10-50 DEG C. The thermal insulation biological medium oxidation treatment method for the domestic sewage has the advantages that investment on treatment of the domestic sewage is small, operating cost is low, maintenance and management are simple, operation is stable, no secondary pollution is produced, the thermal insulation biological medium oxidation treatment method for the domestic sewage is not influenced by regions and seasons and effluent quality can meet water quality standard of landscape surface water.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a thermal insulation biological medium oxidation treatment method for domestic sewage. Background technique [0002] According to relevant data, as of 2010, the total annual waste (sewage) water discharge in my country has reached 62 billion tons, most of which are directly discharged into rivers and lakes without treatment, and nearly a quarter of the lakes have been polluted. There are different degrees of pollution. Nearly 60% of the cities do not have sewage treatment plants, and the domestic sewage in rural areas is basically discharged directly without treatment. The treatment of rural domestic sewage has affected the construction of modern new countryside. my country is a large agricultural country with a large population, and there is a serious shortage of water resources. The per capita water resource is only 2,200 cubic meters, which is 1 / 4 of the world...
