Abstract

The invention relates to the technical field of sewage treatment, particularly a mixed biochemical water purifying agent and application thereof in sewage treatment. The biochemical water purifying agent compounded from a TP1-TP2-HH mixed bacterium solution and a liquid nano polyaluminum chloride can completely adsorb and precipitate suspended substances in the sewage, so that the sewage is free of the suspended substances; and the nano polyaluminum chloride with high adsorption capacity can effectively remove rust, silt, peculiar smell and other pollutants in water. The mixed biochemical water purifying agent has the characteristics of high efficiency, no pollution, low sewage treatment cost, high dirt removal rate (up to 98.5%), high solid content removal rate (up to 95.5%) and high oil content removal rate (up to 99.3%); all the indexes can reach or exceed the national standard; and thus, the mixed biochemical water purifying agent is very suitable for wide popularization and use in domestic sewage or oilfield recovered sewage treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a mixed biochemical water purifier and its application in sewage treatment. Background technique [0002] my country's existing sewage treatment mostly uses chemical materials or mineral inorganic acid extraction technology, such as using aluminum sulfate plus activator, bactericide and other methods, or using bleaching powder combined with alkali and alum, but it cannot achieve rapid degradation of organic and harmful substances to purify and improve Water quality, maintaining the ecological balance of the water environment. [0003] At present, the water purification agent of microorganisms and nanomaterials has the following water purification mechanism: [0004] 1. The water purification mechanism of microbial water purifiers [0005] 1. Microbial flocculation [0006] At present, the flocculation mechanism of microbial flocculants mainly includes capsule theory, e...
