Abstract

The invention discloses an enzymatic phosphorus removal agent. The enzymatic phosphorus removal agent includes a biological enzyme phosphorus removal agent and a chemical phosphorus removal agent, and the weight ratio of the biological enzyme phosphorus removal agent to the chemical phosphorus removal agent is 1:8-10; The biological enzyme phosphorus removal agent includes the following raw materials in parts by weight: 25 to 40 parts of microbial enzymes, 10 to 15 parts of microbial probiotics, and the microbial enzymes are phosphotransferase and microbial protease; the chemical phosphorus removal agent includes the following weight: Parts of raw materials: 25-45 parts of polyferric salt, 15-25 parts of polyaluminum salt, 3-8 parts of silicon-calcium slag. In the present invention, by combining the biological enzyme phosphorus removal agent and the chemical phosphorus removal agent according to a certain ratio, it not only reduces the adverse effects of metal salts on microorganisms, but also avoids the possibility of reducing the efficiency of phosphorus removal under anaerobic conditions. Synergize with each other to further improve the phosphorus removal effect and reduce the dosage of chemicals and metal salts. The invention also provides a preparation method of the enzymatic phosphorus removal agent.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an enzymatic phosphorus removal agent and a preparation method thereof. Background technique [0002] With the development of industry and agriculture and the growth of population, the production and consumption of chemical fertilizers, pesticides, and phosphorus-containing detergents in China have increased rapidly, and the eutrophication of water bodies caused by water pollution has become increasingly serious. Many industries, such as tourism, also pose a huge threat to drinking water sanitation and food safety. The main nutrients that cause water eutrophication include organic carbon, nitrogen, phosphorus, potassium, etc. Organic carbon in sewage can be basically removed after general biological treatment, and the content of other components other than nitrogen and phosphorus is relatively The demand in the process is extremely low and will not be the lim...
