Abstract

The invention discloses a sludge leavening agent. The sludge leavening agent is prepared from the following raw materials in parts by weight: 15-25 parts of bacillus subtilis, 10-20 parts of bacillus stearothermophilus, 8-15 parts of lactic acid bacteria, 5-10 parts of silicate bacteria, 4-10 parts of nocardia, 9-16 parts of a zotobacter chroococcum, 1-6 parts of saccharomyces cerevisiae, 1-5 parts of flavobacterium oryzae, 2-3 parts of photosynthetic bacteria, 1-3 parts of streptomyces microflavus, 6-13 parts of cellulase, 5-12 parts of amylase and 5-6 parts of xylanase. The sludge leavening agent provided by the invention is environmentally friendly, pollution-free, low in operation cost, small in floor space, and capable of effectively killing pathogenic bacteria, the parasites and the like in the sludge, degrading toxic and harmful substances, accelerating sludge deodorization and dehydration and decomposing nutrition ingredients which are difficult to absorb by crops.

Description

technical field [0001] The invention relates to a fermentation agent for treating sludge, which belongs to the field of environmental protection biotechnology. Background technique [0002] Municipal sludge is the sludge left in the sewage treatment tank after the urban sewage is purified and discharged. A sewage treatment plant with a daily processing capacity of 100,000 tons can produce tens of thousands of tons of sludge every year. Sludge has high water content, high viscosity and bad smell; wet sludge also contains harmful bacteria such as pathogenic bacteria and parasite eggs, which will cause secondary pollution to the environment. Therefore, the development and utilization of municipal sludge to solve its secondary pollution to the environment has become an urgent problem to be solved. [0003] The treatment methods of municipal sludge mainly include landfill, incineration, ocean dumping and land utilization. However, landfilling seriously encroaches on land, and i...
