Problems solved by technology

Alcohol fermentation industry is a relatively serious pollution industry. The organic waste water produced every year reaches 60 million cubic meters. The waste water is usually treated and discharged through high-temperature anaerobic and aerobic processes. During the high-temperature anaerobic treatment of the whole waste, there will be A large amount of anaerobic distiller's grains, the water content is 65% to 70%, these distiller's grains have been treated as waste for a long time, easy to cause secondary pollution, and have not realized resource utilization
Conventional bio-organic fertilizer composting fermentation has a long fermentation cycle, extensive production, and difficult to guarantee quality. It is urgent to develop an efficient and stable organic fertilizer production process

Abstract

The invention discloses a method for manufacturing organic fertilizer. The method comprises the following steps that (1) complex microbial inoculant culture solutions are prepared, and seed excitation, seed expanding cultivation and compound cultivation are carried out on a first strain, pseudomonas chlororaphis, bacillus subtilis and bacillus megatherium in sequence to obtain the complex microbial inoculant culture solutions; (2) composting fermentation is carried out, the complex microbial inoculant culture solutions are mixed with alcohol anaerobic grains with the ratio that 0.5 L to 1.2 L of the complex microbial inoculant culture solutions are adopted in each ton of the alcohol anaerobic grains, fermentation is carried out for 15 days to 30 days at the temperature of 55 DEG C to 65 DEG C with the composting moisture content of 40 percent to 45 percent, and stacking is carried out for 15 days to 20 days. The method has the advantages that on one hand, waste pollution can be reduced; on the other hand, appreciation and resource utilization of waste can be achieved. The production period is short, and the technology is stable.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a preparation method of organic fertilizer. Background technique [0002] Alcohol is an important industrial and food raw material, which is widely used in chemical industry, food and beverage, daily chemical and medical and health industries. It is also a widely used renewable energy source, so it has a very wide range of applications and development prospects. my country's alcohol production capacity has reached more than 6 million tons, but the operating rate is about 75%. At present, the main raw materials for alcohol production are cassava, corn, molasses and so on. Alcohol fermentation industry is a relatively serious pollution industry. The organic waste water produced every year reaches 60 million cubic meters. The waste water is usually treated and discharged through high-temperature anaerobic and aerobic processes. During the high-temperature anaerobic treatment of...
