Medicament for improving bed mud anaerobic condition of black and odor water and preparation method

Abstract

The invention discloses a medicament for improving bed mud anaerobic condition of black and odor water and a preparation method. The medicament is prepared from the following materials: 10-16 parts ofCaO, 16-20 parts of Al2(SO4)3, 12-14 parts of FeO, 8-12 parts of sodium carbonate, 4-6 parts of sodium bicarbonate, 20-32 parts of coal-based activated carbon, 1-3 parts of hydrolase, 1-3 parts of polyacrylamide, and 1-2 parts of compound microbial strain. The preparation method comprises the following steps of 1) proportioning materials; 2) crushing materials, and preparing activated carbon intosemispheres with through holes; 3) forming spheres based on the semispherical activated carbon, feeding other materials in the spheres, and sealing; and 4) preparing the compound microbial strain into suspending liquid and feeding the suspending liquid into the activated carbon spheres. The activated carbon is attached to the compound microbial strains so as to adsorb the compound microbial strains effectively, can be firmly combined with carriers, improves the reduction-oxidation potential and increases dissolved oxygen of the water and bed mud.

Description

technical field [0001] The invention belongs to the technical field of polluted bottom sludge treatment, and in particular relates to a medicament for improving the anaerobic condition of black and odorous water bottom sludge and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, a large amount of industrial wastewater and domestic sewage have entered rivers, lakes and other water bodies, resulting in serious pollution of rivers and lakes, and the water body is black and smelly and eutrophic. . Sludge contains a large amount of organic matter such as protein and polysaccharides. At present, 85% of lakes in my country have experienced eutrophication to varying degrees. Chaohu Lake, Taihu Lake and Dianchi Lake have experienced large-scale algae blooms, which will affect the production and life of surrounding residents and the safety of drinking water. have a serious impact. After pollutants enter riv...
