Preparation method of indigenous bacterium blocks for treating dystrophication

Abstract

The invention relates to indigenous bacterium blocks for treating dystrophication, which are characterized in that: the indigenous bacterium blocks in various shapes are prepared by mixing and uniformly stirring 61 to 65 weight percent of indigenous bacteria culture mud with the water content of 48 to 55 percent, 23 to 28 weight percent of calcium hydroxide Ca(OH)2, 2 to 3 weight percent of coarse granulated sugar, 1.5 to 3 weight percent of calcium peroxide CaO2 and 4 to 5.5 weight percent of glutinous rice paste, feeding the mixture into a mold and pressing, wherein the indigenous bacteria culture mud is prepared by the following steps of: extracting a river lake substrate sludge sample and separating to obtain required indigenous bacteria, namely anaerobic and facultative strains; multiplying the indigenous bacteria; and anaerobically adjusting to make the indigenous bacteria in a dormant state. The indigenous bacterium blocks are easy to transport and throw; and when the indigenous bacterium blocks are thrown into rivers and lakes, the indigenous bacteria in the indigenous bacterium blocks quickly multiply in the rivers and lakes and decompose organic pollutants so as to eliminate darkening and odor of the rivers and lakes, which is a means for treating pollution by using waste.

Description

【Technical field】 [0001] This field belongs to the field of environmental protection, and in particular relates to a preparation method of indigenous bacterial block for treating river and lake pollution. 【Background technique】 [0002] Due to the rapid increase of the population in the convenient urban area of ​​the economic development, the improvement of people's living standards, and the expansion of the urban and rural areas, the rivers and lakes that used to be used as landscapes, irrigation, flood drainage, storage, and pollution in the past have generally suffered from black and smelly phenomena. [0003] The root causes of the black and smelly rivers and lakes are as follows: 1. Rain and sewage diversion: Although a centralized domestic sewage pipe network is built in densely populated areas to intercept sewage and sewage to the sewage treatment plant, the sewage from the laundry of the migrants in the rented houses is discharged from the balcony. The sewage interce...

AI Technical Summary

Problems solved by technology

However, it is unreasonable to take engineering measures for river regulation at present. The water source of rivers and lakes must rely on the flood season to intercept sewage, that is, to cut off the flow. During the dry season, most of the biodiversity is lost; sludge cleaning, water replenishment, and water diversion are only to transfer sludge pollution and pollution. The diluted water body is transferred to the downstream, causing the water quality of the water area to deteriorate; sometimes hardware facilities are built or aerators are installed in rivers and lakes
