Abstract

The invention provides a purifying agent for efficiently treating domestic sewage. The purifying agent for efficiently treating the domestic sewage sequentially comprises a first heavy metal wastewater flocculating layer, a first fixed microbial composite material layer, a second heavy metal wastewater flocculating layer and a second fixed microbial composite material layer from top to bottom, wherein each of the first heavy metal wastewater flocculating layer and the second heavy metal wastewater flocculating layer is prepared from the following raw materials: hydroxymethyl cellulose, a metal ion solution and a plant extract; the metal ion solution comprises a ferric chloride solution and a manganese sulfate solution; the plant extract comprises a green tea extract, a bee flower extract, a carrot extract, a grape seed extract, a dandelion extract, a purslane extract, a rosemary plant extract, a spiraea extract, an epilobium angustifolium extract, an empetrum nigrum extract and an aronia extract.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular, the invention relates to a purifying agent for efficiently treating domestic sewage. Background technique [0002] In sewage treatment, the traditional activated sludge method is a widely used treatment method. This method mainly uses the microorganisms contained in the activated sludge to remove organic matter in the water. At the same time, these microorganisms can also play a good role in denitrification. Phosphorus removal effect. However, in the traditional activated sludge method, the sludge will flow with the sewage, which is easy to cause loss and waste resources. [0003] Immobilized microorganism technology can immobilize the screened out dominant bacteria that can degrade specific substances. The application of this technology can make the sewage treatment system specific, enhanced tolerance, stable treatment effect, simple operation and management, and the degradation e...
