Method and device for realizing liquid composting of organic wastewater by using humifying microorganisms

Abstract

The invention belongs to environment microbe techniques and fields of organic waste gases and organic wastewater reclamation, and in particular relates to a method for achieving organic wastewater liquid composting based on a humic microbe culture device. The method comprises the following steps: enriching and culturing humic microbes by using the microbe culture device, supplying a culture liquid which is rich in the humic microbes to a fermentation tank, and constructing a microbial community structure which can prompt smooth progress of organic sewage liquid composting inside the fermentation tank. By adopting the method, a sewage reclamation solving scheme with low cost and high additional values is provided for pollution discharge companies, an ecologic circulation production structure which emphasizes on organic sewage reclamation and application of reclamation products is formed, the pollution control investment is reduced, the environment is improved, and the benefits are improved.

Description

technical field [0001] The invention belongs to the field of environmental microorganism technology and organic waste gas and organic waste water resource utilization, and specifically relates to a method for realizing liquid composting of organic waste water based on the microbial strengthening effect of a humification microorganism culture device. Background technique [0002] Economic development and the improvement of people's living standards have brought about a large number of material needs. In order to meet the growing demand, the scale of large-scale farms, slaughterhouses, meat processing plants, food factories, and catering industries has increased rapidly, resulting in the discharge of organic sewage The volume is increasing year by year. China's huge population base and huge demand have led to pollution emissions that have ranked first in the world. [0003] In particular, if the organic sewage is not properly treated and discharged at will, it will produce st...

Problems solved by technology

However, this method produces a large amount of stench and pollutes the surrounding environment, and there is a problem of sewage seeping down and polluting groundwater.

Due to the environmental pollution caused by improper disposal of waste, the number of petitions and complaints caused by the masses has also increased year by year. Therefore, the disposal of organic wastewater has become a major bottleneck restricting the development of these sewage enterprises.

[0004]On the other hand, in order to ensure production, the modern planting and breeding industry uses a large amount of chemical fertilizers, pesticides and veterinary drugs, which hastened the pollution and functional degradation of agricultural land and natural water bodies. Food safety issues such as excessive pesticide residues in agricultural products and excessive antibiotics in livestock and poultry products have also arisen

However, due to the inappropriate use of antibiotics and other drugs in the currently widely used breeding methods, the subsequent treatment process of organic pollutants has been affected, such as failure of compost fermentation caused by excessive residues of antibiotics, instability of sewage treatment systems, etc.
