Abstract

The invention discloses a biology treating agent for inhibiting water eutrophication and a preparing method thereof. The biology treating agent is prepared from, by mass, 8-15 parts of radix mirabilis, 5-10 parts of clove, 3-7 parts of Xanthium sibiricum, 30-45 parts of modified diatomaceous earth, 40-50 parts of poly aluminum ferrous chloride, 12-15 parts of ferric sulfate, 12-15 parts of trichloro-isocyanuric acid, 20-25 parts of potassium citrate and 25-30 parts of disodium edetate dihydrate. By means of addition of the radix mirabilis, the clove and the Xanthium sibiricum and calcination treatment, the adsorption property of the modified diatomaceous earth and effects such as coagulation and electrical neutralization of polycation are effectively brought into play, alumen ustum is large and compact, the sedimentation speed is high, the effects of removing suspended substances like blue-green algae, turbidity, nitrogen and phosphorus and the like are remarkable, treated water is transparent, the water quality and the acid-base property are stable, and the biology treating agent has effects of many kinds of agentia such as a corrosion inhibitor and bactericide, so that water eutrophication is prevented.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biological treatment agent for inhibiting eutrophication of water bodies and a preparation method thereof. Background technique [0002] Eutrophication refers to excessive discharge of phosphorus and nitrogen-containing compounds into the water body, destroying the original ecological balance, causing algae to multiply rapidly, and the growth cycle is short. After the death of algae and other plankton, they are decomposed by aerobic microorganisms, which continuously consume dissolved oxygen in the water, or are decomposed by anaerobic microorganisms, and continuously produce hydrogen sulfide and other gases, which continuously deteriorate the water quality from two aspects, causing fish and other aquatic organisms mass death. During the decay process of algae and other plankton residues, nutrients such as nitrogen and phosphorus are released into the water for a new ...
