Urban domestic sewage treatment plant
Main technical contents
I. Basic principles
Shanxi fertile soil has adopted a set of new technologies and methods for sludge treatment and disposal, which are basically based on the theories and principles of biological fermentation, compound nutrition and soil health. The specific process includes: step 1, changing complete flocculation into semi-flocculation by sludge softening technology to alleviate the insoluble defect of municipal domestic sewage sludge formed in the flocculation process; Step 2, adopting a heap fermentation process, adding human phosphate soluble substances and heavy metal passivation substances, inoculating fertile soil (initiator) and VT bacteria to further soften the sludge and release effective nutrients; And 3, puffing and granulating by high-temperature and high-pressure thermal spraying, and inoculating bacteria for the second time to obtain a three-dimensional organic-inorganic-microbial compound.
Second, the key technologies
Including biological high nitrogen source fermentation technology, efficient microbial preparation and domestication technology, natural dehydrating agent proportional replacement polyacrylamide technology, phosphoric acid neutralization softening and heavy metal passivation technology, VT bacteria spray inoculation technology, thermal spray granulation technology and so on.
Typical scale
Annual output of 20,000 tons of organic fertilizer (treating 654.38+200,000 tons of sludge)
Main technical indicators and conditions
I. Technical indicators
