Abstract

The invention provides a sewage purifying agent which is prepared from the following components and raw materials in parts by weight: 90-100 parts of modified attapulgite, 10-15 parts of montmorillonite powder, 5-7 parts of chitosan, 4-5 parts of gypsum powder, 5-6 parts of quartz stone powder, 10-12 parts of polyethylene glycol, 2-4 parts of glutinous rice flour, 8-10 parts of poly-3-hydroxybutyrate, 0.1-0.2 part of zinc sulfate, 0.1-0.2 part of manganese sulfate, 0.1-0.2 part of potassium chloride and 0.2-0.5 part of ferrous sulfate. When the sewage purifying agent is prepared, the modified attapulgite and other components and raw materials contained in a formula are sufficiently mixed, granulated and packaged. The sewage purifying agent provided by the invention has the advantages of sewage purifying and sterilizing effect and long residual action.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage purifying agent and a preparation method thereof. Background technique [0002] With the acceleration of modern urbanization and industrialization, the pollution of rivers and water sources on which human beings depend is becoming more and more serious, and the water body appears to be black and smelly seasonally or all the year round. For example, the Suzhou Creek in Shanghai, the Outer City River in Suzhou, the Qinhuai River in Nanjing, the Pearl River in Guangdong, the Yongding River in Beijing, etc., as well as countless drainage ditches, ponds, seaside or riverside wetlands, park wetlands, etc. Serious pollution, in some places even threatens human drinking water sources, reservoirs, etc. Water pollution seriously threatens the quality of life and health of residents, restricts the development of the city itself, and destroys the beautiful image of the city. Theref...
