Preparation method of biological bacterial agent for treating water body pollution

Abstract

The invention discloses a preparation method of a biological bacterial agent for treating water body pollution. The preparation method comprises the following steps: firstly, based on parts by mass, mixing 10 to 20 parts of lactobacilli, 10 to 20 parts of saccharomycetes, 40 to 70 parts of photosynthetic bacteria and 4 to 8 parts of nitrite bacteria, and culturing for 24 hours; secondly, mixing peanut shell particles, microcrystalline cellulose and mixed bacteria liquid; thirdly, preparing a bioorganic acid solution with the mass concentration of 12 to 15 percent, soaking activated carbon, then, evaporating to remove water, and adding the activated carbon into the mixture which is obtained in the second step; fourthly, freezing-drying the mixture which is prepared in the third step, decreasing the temperature to 1 DEG C first, then decreasing the temperature to -25 DEG C, next, decreasing the temperature to -35 DEG C, decreasing the pressure intensity to 1 Pa, and heating to 5 DEG C. The biological bacterial agent has a very good effect on pollution treatment, can excite the activity of existing microorganisms in a water body, accelerate the growth and reproduction of the microorganisms, and promote the water body to recover quickly.

Description

technical field [0001] The invention relates to a preparation method of a biological bacterial agent for controlling water body pollution. Background technique [0002] River water pollution has become the main factor affecting regional socio-economic development and restricting the improvement of people's living standards. Surveys have shown that more than 90% of the rural water ecology in the Yangtze River Delta region has lost its basic functions, urban and rural rivers have been severely degraded due to pollution and ecosystems, and the water quality of the rivers has basically fallen into Class V or worse. Most rivers are seriously polluted, rich Nutritization, the most important pollution indicators are permanganate index and ammonia nitrogen. In addition, most of the river water turns black and smelly, and the pathogenic bacteria exceed the standard, resulting in a severe environmental and ecological situation, which seriously affects the ecology, production and life ...

AI Technical Summary

Problems solved by technology

Usually there are self-purifying microorganisms in rivers with better ecology and less pollution, but the self-purifying function has been lost in polluted rivers, self-purifying microorganisms are lacking or the amount of bacteria is too small, and microorganisms in nature can be artificially cultivated, isolated and domesticated , utilized, and further used for environmental governance are very few
