Abstract

The invention provides an industrial sludge deep dehydration conditioning agent and a preparation method and application thereof, and relates to the technical field of sewage and sludge treatment. Theconditioning agent is prepared from rectorite, coal gangue, kaolin, biological bacteria, coconut shell fibers, cellulose acetate, chitosan, protease, lactobacillus plantarum, borax, cyanobacteria powder, iron sulfate, calcium carbonate, aluminum sulfate, citric acid and deionized water. The conditioning agent can effectively improve the dewatering performance of the sludge, realizes a low cost, is environmentally friendly, is non-toxic and harmless, does not cause secondary pollution to the environment, realizes a low dehydration cost, has good environmental benefits, is easy to use in industrial sludge deep dehydration and greatly reduces the moisture content of the sludge.

Description

technical field [0001] The invention relates to the technical field of sewage sludge treatment, in particular to an industrial sludge deep dehydration conditioner and its preparation method and application. Background technique [0002] With the rapid development of cities and industries, the discharge of urban domestic sewage and industrial sewage is increasing, so that the amount of by-product sludge produced in sewage treatment is increasing. How to treat these sludge has also become a social development. unavoidable problem. At present, there are three main methods of sludge treatment: landfill, composting and incineration. Sludge has the characteristics of "four highs": first, high moisture content; second, high organic matter content, which is easy to rot and odor; third, heavy metal content Fourth, the germ content is high, containing a large number of bacteria, parasites, and viruses. Without harmless treatment, the sludge is discarded arbitrarily and simply land...
