Abstract

The invention provides a cleaning treatment agent for municipal sewage sludge and a preparation method thereof, and relates to the field of cleaning treatment agents. The cleaning treatment agent consists of a component A and a component B, wherein the component A comprises the following raw materials in parts by weight: 12-18 parts of polyaluminum ferric silicate, 10-14 parts of modified graphitephase carbon nitride, 9-12 parts of ferric sulfate, 5-12 parts of hydrogen peroxide, 11-17 parts of carboxymethyl chitosan, 12-18 parts of polyacrylamide, 5-10 parts of polyalumina, 3-5 parts of acetic acid, 4-7 parts of citric acid, 9-13 parts of polyvinylimide, and 4-10 parts of acrylic chloride; and the component B comprises the following raw materials in parts by weight: 12-18 parts of nitration bacteria, 5-14 parts of acid bacillus, 3-9 parts of bacillus cereus, 4-9 parts of white rot fungi, 10-14 parts of bacillus subtilis, and 6-17 parts of an inorganic particle. Aiming at problems existing in the prior art, the excellent municipal sewage sludge cleaning effect is achieved by optimizing the formulation raw materials.

Description

technical field [0001] The invention relates to the field of cleaning treatment agents, in particular to a cleaning treatment agent for urban sewage sludge and a preparation method thereof. Background technique [0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage within urban areas. Generally, it is collected by urban pipes and canals and should be treated by urban sewage treatment plants before being discharged into water bodies. In addition to containing a large amount of organic matter, germs and viruses in urban sewage, due to the high development of industry, the water volume of industrial wastewater (accounting for about 60-80% of the total urban sewage), the water quality is becoming more and more complex and the pollution of runoff sewage is becoming more and more serious, making urban sewage Contains various types and levels of various toxic and harmful pollutants. At the same time, with the acceleration of urbanization, the amou...
