Sludge activating ball and manufacture method thereof

Abstract

The invention provides a sludge activating ball and a manufacture method thereof; the sludge activating ball is mainly prepared from the following raw materials: garden burnet, field pennycress, lumbricus, sargentgloryvine stem, fructus cnidii, old ginger, sea salt, distillation wood vinegar liquid, brown sugar, wheat bran, trass and environment-friendly YangSu; the manufacture method comprises the following steps: mixing garden burnet, field pennycress, lumbricus, sargentgloryvine stem, fructus cnidii, old ginger and sea salt for the same ratio, grinding the mixture, mixing the mixture with the trass in a ratio of 1:1, mixing the brown sugar with the mixture in a ratio of 1:1.5 and pouring the obtained mixture into the mixed liquid composed of the distillation wood vinegar liquid and the environment-friendly YangSu in a ratio of 1:1, adding the wheat bran the weight percentage of which is 10%, kneading into the clump, placing the clump in the moist, cool and lucifugal environment or on a wood shelf, the environment temperature is about 37 DEG C, cultivating for 15 days, and if the surface of the clump turns white, finishing fermentation for use. The sludge activating ball is slowly dissolved and released during the using process, so as to increase the beneficial microorganism of the sludge, improve and activate the sludge and remove the soil odor.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a sludge activation ball and a manufacturing method thereof. Background technique [0002] Sludge is the product of sewage treatment, which is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloidal sludge, etc. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. [0003] my country's urban sewage treatment plants have basically achieved the initial reduction of sludge, but have not achieved the stabilization of sludge. According to statistics, about 80% of the sewage plants have sludge concentration...

AI Technical Summary

Problems solved by technology

According to statistics, about 80% of the sewage plants have sludge concentration and dehydration facilities, which have achieved a certain degree of reduction; about 80% of the sludge has not been stabilized, and the sludge contains malodorous substances, pathogens, persistent Pollutants such as organic matter are transferred from sewage to land, leading to further diffusion of pollutants, which greatly reduces the environmental emission reduction benefits of large sewage treatment facilities that have been built and put into operation
