Abstract

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.

Description

technical field [0001] The invention relates to a biochemical water purifier in the field of polluted water, in particular to a composite enzyme biochemical water purifier and a preparation method thereof. Background technique [0002] At present, with the rapid advancement of my country's industrialization process, environmental pollution, especially water pollution, has become increasingly serious, seriously affecting people's health and living environment. The use of water purifiers to treat industrial wastewater and urban sewage is one of the most commonly used methods in water treatment, and it is also one of the important means to eliminate pollution and protect the environment. [0003] At present, the commonly used water treatment purifiers mainly include two categories: inorganic flocculants and organic polymer flocculants. These two types of chemical products are highly targeted products, and when the components of the water system to be treated are relatively com...
