Abstract

The invention discloses a novel efficient chemical. The novel efficient chemical is prepared from the following raw materials in parts by weight: 72 to 100 parts of modified coconut shell powder, 42 to 46 parts of decomposed soybean meal, 9 to 10 parts of complex microbial inoculants, 3.2 to 4 parts of astaxanthin, 5 to 9 parts of kieselguhr, 4 to 6 parts of sodium humate, 0.6 to 1 part of sodium lignin sulfonate, 0.3 to 0.5 part of soybean oligopeptide powder and 0.5 to 0.8 part of dodecyl methacrylate. The novel efficient chemical is prepared through the steps of raw material mixing, crushing, drying and the like. The novel efficient chemical has the advantages of no toxicity, safety, environmental protection and the like, is applied to treatment of aquaculture wastewater, has a COD removal rate of 94.9% or above, and can be vigorously popularized and applied.

Description

【Technical field】 [0001] The invention relates to the technical field of wastewater treatment, in particular to a novel high-efficiency medicament, a preparation process and its application in aquaculture wastewater treatment. 【Background technique】 [0002] Most domestic aquaculture uses closed water areas such as ponds and reservoirs. The self-purification ability of water bodies is far lower than the eutrophication rate of water bodies. The water environment is greatly damaged. The same area cannot meet the sustainable development of aquaculture for a long time. The way of introducing large rows not only consumes a lot of water resources, but also due to the application of feed, the use of fungicides and disinfectants, the accumulation of animal and plant carcasses and animal manure, it leads to a large accumulation of organic matter, nitrogen and phosphorus in the breeding water, lead to deterioration of aquaculture water. According to the research, it is found that the...
