The invention relates to a biochemical water purifying agent, in particular to a composite
enzyme biochemical water purifying agent and a preparation method thereof, and belongs to the field of polluted water. The composite
enzyme biochemical water purifying agent is prepared from the following components in percentage by weight: 20 to 30% of a multi-
enzyme compound, 1 to 6% of a diatomite extract, 3 to 5% of
chitin, 2 to 10% of a complexing agent, 50 to 70% of deionized water, 2 to 10% of a
carbon source, 1 to 5% of dodecyl dimethyl benzyl
ammonium chloride, and 0.05 to 0.1% of
polyacrylamide, wherein the sum of weight percent of all components is 100%. The composite enzyme biochemical water purifying agent has the advantages that the water purifying agent can be used for effectively catalyzing and degrading according to the features of different pollutants; the formula of the product is poisonless and harmless, and the environment-friendly effect is realized; the production technology is concise, scientific and reasonable, and the environment-friendly effect is realized; the water purifying agent is suitable for the fields of
eutrophic water body, domestic
sewage, industrial
wastewater, cleaning and deodorizing of communities, cleaning and deodorizing of garbage, composting of garbage, treatment of garbage percolate, treatment of
wastewater in culture industry, soil improvement, daily cleaning of road vehicles, and the like.
