preparation example Construction

[0034] The preparation method of the Rhodococcus erythropolis sludge flocculant of the present invention is realized by the prior art, and can be prepared by the following method. The biological flocculant is obtained by flocculating the acid hydrolysis product of the crop straw and the sludge obtained from the chemical waste water, and mixed through It is made by fermenting Rhodococcus erythrococcus, and the specific production steps are as follows:

[0035] 1) Seed culture of the strain: inoculate the strain from the preservation medium into the seed medium, and cultivate it at 32° C. and 200 rpm for 20 hours to obtain a seed solution;

[0036] 2) Preparation of fermentation medium: crop straw and sulfuric acid with a concentration of 1.5% by weight at a solid-to-liquid ratio of 1:8, soak for 1.5h, settle at 5000rpm for 15min, take the clear liquid and the sludge obtained by flocculating chemical wastewater to The volume ratio is 1:8, and the mixed solution is sterilized to ...

Abstract

The invention discloses a biological enzyme purifying agent for treating black and odorous river courses. The parts by weight of each component are: 20-50 parts of biological enzyme, 10-15 parts of Rhodococcus erythropolis sludge flocculant, chitosan quaternary ammonium 10-18 parts of salt, 10-15 parts of grape seed extract, 5-15 parts of sweet potato extract, 10-15 parts of polyaluminum chloride, and 8-12 parts of polyacrylamide. Under the joint action of multiple components, the present invention has remarkable water purification effect, can significantly improve water quality, increase dissolved oxygen content in water, inhibit the growth of harmful bacteria, remove suspended solids and harmful algae in water, and reduce ammonium nitrogen and nitrate levels in water. Nitrogen content, clarify water body, eliminate odor, promote the degradation of pollutants, and promote the healthy development of water ecology. The present invention has abundant raw material resources, simple preparation process of the water purifying agent, short production cycle, simple operation, low production cost, and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the technical field of ecological environment, in particular to a biological enzyme purifier for treating black and odorous rivers and a preparation method thereof. Background technique [0002] Black and odorous water is an extreme manifestation of organic pollution in water. It is caused by the lack of oxygen in the water and the corruption of organic matter. When a large amount of organic pollutants enter the water, under the purification of aerobic microorganisms, a large amount of oxygen in the water is consumed. Transform the water body into an anoxic state, resulting in a large number of anaerobic bacteria. [0003] Due to the problems left over from history, most urban rivers are carrying sewage, and a large number of pollution sources such as domestic sewage, domestic garbage, and industrial wastewater enter the river, resulting in the phenomenon of black and smelly rivers, which seriously affects the normal life of su...
