Cleaning agent for treating eutrophic water and preparation method thereof

Abstract

The invention provides a cleaning agent for treating eutrophic water and a preparation method thereof. The cleaning agent for treating the eutrophic water comprises the following raw materials in parts by weight: 1-2 parts of mixed bacteria, 25-35 parts of vinasse, 5-10 parts of pine nut, 30-50 parts of spirulina protein powder, 30-50 parts of palygorskite, 30-50 parts of kieselguhr, 30-40 parts of xanthan gum, 10-20 parts of activated coal gangue, 10-20 parts of medical stone, 40-60 parts of potato, 20-25 parts of potherb mustard, 30-60 parts of wheat bran, 4-8 parts of rosemary, 20-40 partsof sodium lignin sulfonate, and 0.5-1 part of chlorella. According to the cleaning agent, the mixed bacteria are capable of degrading eutrophic nitrogen, phosphorus and various organic nitrides; potherb mustard and rosemary are capable of prolonging the proliferative stage of the mixed bacteria and reducing the recovery time of eutrophic water; palygorskite, kieselguhr, activated coal gangue, xanthan gum, medical stone and sodium lignin sulfonate are capable of adsorbing pollutants in water. With the adoption of the cleaning agent, the eutrophic water can be cleaned; the water quality of the eutrophic water can be recovered; and the time of recovering the eutrophic water is decreased.

Description

technical field [0001] The invention relates to the field of purifying water bodies, in particular to a purifying agent for treating eutrophic water bodies and a preparation method thereof. Background technique [0002] Water eutrophication, also known as water bloom, refers to the phenomenon of water quality pollution caused by excessive plant nutrients such as nitrogen and phosphorus in lakes, rivers, reservoirs and other water bodies. Nitrogen and phosphorus are generally considered to be the key factors causing this environmental problem. The sources of nitrogen and phosphorus in water bodies come from endogenous phosphorus and exogenous phosphorus. Exogenous nitrogen and phosphorus mainly come from sewage entering the water body, which can be effectively controlled through pollution control measures; Deposition of debris in bodies of water. The continuous accumulation and release of endogenous nitrogen and phosphorus have caused great difficulties in the control of wa...

AI Technical Summary

Problems solved by technology

Dredging the bottom sediment of heavily polluted lakes can easily lead to the suspension and diffusion of bottom sediments, which promotes the release of nitrogen and phosphorus nutrients in the sediments and the metal ions adsorbed by them, thus making the water environment vulnerable to sediment pollution. The risk of secondary pollution from heavy metal ions and nitrogen and phosphorus nutrients released in the water; although adding chemical agents can make the water transparent and improve the water quality to a certain extent, long-term use may accelerate the aging of the lake and trigger new ecological conditions. question

In comparison, physical and chemical treatment methods are costly, and the control of eutrophication is not thorough, and can only be effective in a short period of time, and are not suitable for long-term use; although biological regulation and bioremediation methods are low in cost, thorough treatment and No secondary pollution, but the effect is slow and the technology is complex

Due to the above-mentioned deficiencies in the existing technologies, the prevention and control effect of eutrophication in water bodies in my country is not obvious, and the problem of eutrophication is becoming more and more serious
