Method for producing microbial agent by using filter mud of sugar mills through fermentation

Abstract

The invention provides a method for producing a microbial agent by using filter mud of sugar mills through fermentation, belonging to the field of the production technology of the microbial agents. The method can produce the high quality microbial agent and treat the pollutions caused by the industrial waste filter mud of the sugar mills at the same time, and also can achieve the circulating economic benefits for the sugar industries. The method comprises the steps of mixing the filter mud of the sugar mills, weathered coal of the humic acid or grass carbon and dried straw to obtain a mixture, controlling the water content of the mixture to 33%-70%, adding the microbial agent into the mixture at a mass ratio of 2% of the microbial agent to the mixture, rapidly stirring to form a homogeneous mixture, loading into a sealing bag, and carrying out anaerobic fermentation for 10 days at a room temperature of the south of China to obtain the microbial agent with an effective living bacteria number being greater than or equal to 300 million/g (higher than the national standard of 200 million/g). According to the invention, the method has the advantages of low cost, simple operation and high product quality, achieves the effective resource utilization through converting the filter mud of the sugar mill into a treasure, solves the problem of the environmental pollution and saves high environmental protection cost for the sugar industries, and brings good economic benefits at the same time, which can form a closed biosphere of the sugar production; and the biosphere creates circulating economic benefits, and brings rich rewards to the sugar industries and the sugarcane farmers.

Description

technical field [0001] The invention belongs to the technical field of microbial bacterial agent production, and relates to a method for producing microbial bacterial agent by fermenting sugar factory filter mud. The method of the invention can control the pollution caused by the industrial waste such as sugar factory filter mud while producing the microbial bacterial agent. Background technique [0002] In the process of producing granulated sugar, my country's sugar industry produces a large amount of waste and pollutants every year. At present, there is no effective way to completely treat these waste pollutants. Sugar enterprises have spent a huge amount of money and can only deal with part of them. Discarding pollutants, but not receiving any economic benefits, has become an important factor restricting the development of the sugar industry. [0003] Sugar factory filter mud is one of them. It is called industrial waste. Due to its high water content, it is not easy to ...

[0002] In the process of producing granulated sugar, my country's sugar industry produces a large amount of waste and pollutants every year. At present, there is no effective way to completely treat these waste pollutants. Sugar enterprises have spent a huge amount of money and can only deal with part of them. Discarding pollutants, but not receiving any economic benefits, has become an important factor restricting the development of the sugar industry

[0003] Sugar factory filter mud is one of them. It is called industrial waste. Due to its high water content, it is not easy to ventilate and it is difficult to dry naturally. , if stacked directly on the land, it will cause soil pollution

At present, there is no good way to effectively deal with the filter mud of sugar factories in my country. Simple mixing or accumulation is mainly used. Many sugar factories need to pay high transportation costs and land occupation fees for filter mud every year. Filter mud has become an important environmental protection tool for sugar factories A problem that the department urgently needs to solve
