Prevention and control medicament based on sewage treatment

Abstract

The invention belongs to the technical field of sewage treatment, and particularly discloses a prevention and control agent based on sewage treatment. The water treatment agent is prepared from the following raw materials in parts by weight: 6-9 parts of bentonite, 3-5 parts of sodium chloride, 3-4 parts of alum, 1.6-2.5 parts of aluminum sulfate, 5-6 parts of calcium oxide, 6-9 parts of magnesium oxide, 1.2-1.8 parts of ferric oxide, 0.6-0.9 part of magnesium oxide, 0.2-0.5 part of sodium oxide, 3-9 parts of silicon dioxide, 5-7 parts of sodium silicate, 4-6 parts of sodium polyacrylate, 9-12 parts of alum, 5-15 parts of additives, 12-18 parts of lithopone, and the remainder being water. By adding the additive, the additive is prepared by mixing menthone, starch, butane, zeolite minerals, activated carbon and diatomite, and impurity particles in sewage are adhered into clusters through the starch and float on the water surface by utilizing the characteristic that the starch is insoluble in water; the zeolite minerals, the activated carbon and the diatomite are combined; so that a good purification effect on the water quality is achieved; the purification treatment effect of the sewage is improved, so that after the prevention and control agent is added into the sewage, suspended solids are flocculated immediately, and precipitation is rapid.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a prevention and control agent based on sewage treatment. Background technique [0002] With the development of economy and society, the improvement of people's living standards and the change of lifestyle, the discharge of domestic sewage in small towns and rural areas in China presents a development trend of large and concentrated discharge. Domestic sewage in small towns and rural areas has become one of the main pollution sources of water bodies in various river basins. However, the water pollution control work in villages and towns is still in its infancy. The investment in water pollution control in villages and towns is low, the treatment rate of domestic sewage is low, and there are many domestic sewage Directly discharged without treatment, resulting in serious water pollution. [0003] Environmental protection directly affects the sustainable devel...

Problems solved by technology

[0005] With the increasingly frequent economic activities of the people in our country, the pollution of water bodies caused by soil erosion, production and domestic sewage is becoming more and more serious. The pollution components include a variety of trace organic pollutants, heavy metal ion pollutants, and high concentrations of large Molecular natural organic matter, simply relying on increasing the dosage of coagulant can no longer solve the problem
