Abstract

The invention provides a composite biological digestion agent as well as a preparation method and application thereof. The biological digestion agent provided by the invention is prepared by the following steps: uniformly mixing a trichoderma koningii strain extracting solution, a bacillus licheniformis strain extracting solution, a geobacillus stearothermophilus strain extracting solution, an aspergillus niger strain extracting solution and an aspergillus nidulans strain extracting solution to obtain a mixed extracting solution; then immersing zeolite in the mixed extracting solution; soakingand taking out the zeolite; drying the zeolite to obtain the composite biological digestion agent. In 2016, the biological digestion agent provided by the invention is used for governing a black andodorous river in the Putuo district, Shanghai; the experimental result indicates that the biological digestion agent provided by the invention can remarkably reduce CODcr, BOD5, NH3-N and TP value inthe black and odorous river.

Description

technical field [0001] The invention belongs to the field of biological treatment, and in particular relates to a compound biological digestion agent for biological treatment of organic pollution in rivers and lakes and a preparation method thereof. Background technique [0002] It is known that in terms of biological treatment of organic pollution in polluted rivers and lakes, the technology of putting microorganisms or microbial products emerging internationally is based on the principle of using biological cultivation or extraction methods to prepare a single bacterial species or biological extract. In the use of single and live bacteria, there are biological safety problems, the efficiency of biological extracts is low, and the current process level is generally low, the cost of preparation is high, the output is low, the product quality is uneven, and there is a lack of effective production. It is difficult to realize the industrialization of production, and it cannot s...
