Domestic sewage treatment method

Номер: CN116462365A
Автор: YANG RUIHONG, WU QICHAO, TAN CHANGFEI, QIAN CHEN, YONG DAMING, SHAN DAN
Принадлежит:

The invention relates to a living sewage treatment method. Domestic sewage is sequentially subjected to pretreatment, aeration precipitation, nitrogen and phosphorus removal and filtration and then can be discharged. Wherein the aeration precipitation comprises a contact oxidation step and an anoxic precipitation step; the nitrogen and phosphorus removal process is carried out in a treatment tank containing an adsorption film; the adsorption film is prepared by taking polyvinylidene fluoride as a carrier material and carrying out composite modification and electrostatic spinning on diatomite/graphene composite powder. Compared with the prior art, domestic sewage is particularly rich in nutrient substances, a conventional adsorption film does not have anti-pollution performance, the prepared composite adsorption film is formed by modifying natural materials diatomite and graphene oxide, the cost is low, and the prepared adsorption film has the advantages of being large in adsorption amount ...
