Abstract

The invention discloses a composition capable of treating domestic sewage. The composition comprises the following components in parts by weight: 2-13 parts of calcium carbonate, 3-7 parts of mica, 6-17 parts of zeolite powder, 21-33 parts of kieselguhr, 0.5-3 parts of alums, 1-6 parts of potassium permanganate, 2-5 parts of ferric trichloride, 5-11 parts of aluminum oxide, and 3-9 parts of titanium dioxide; a microbial preparation for providing support to remove nitrogen in the sewage is added during the use of the composition. According to the preparation method, the chemical method and the biological method are combined; in addition, the microorganism treatment conditions are controlled, so that the short-cut nitrification and denitrification process can be achieved; the energy consumption is reduced; the processing speed is increased; and the removing efficiency of nitrogen in water is increased.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a composition for treating domestic sewage and a preparation and use method thereof. Background technique [0002] Human activities have caused a large number of people to gather in cities, and the population density in cities has risen linearly. It has also led to a large amount of domestic sewage being directly discharged into rivers, and domestic sewage contains a large amount of nutrient-rich substances, such as nitrogen and phosphorus. The direct discharge of untreated domestic sewage causes many problems, directly pollutes the river, and causes a large number of aquatic organisms to die in the river; it also affects the appearance of the city, especially many sewers directly connect the sewage to the lakes in the city, Serious pollution and stinky lakes have been caused; solving the problem of domestic sewage treatment is a major issue of urban development.
