Household refuse and domestic sewage synchronous processing method

Abstract

The invention provides a household refuse and domestic sewage synchronous processing method, which comprises the following steps: sorting household refuse, separating inorganic substances which cannot be fermented and recycling for reutilization; crushing fermentable raw materials after sorting, and mixing the crushed fermentable raw materials with sewage, pretreating, and carrying out anaerobic decomposition and aerobic decomposition so as to effectively decompose various organic matters in the sewage. The quality of the processed water accords with related national emission standard. According to the method, household refuse and domestic sewage are processed on the spot. Thus, land occupation of refuse landfills is greatly saved, garbage transportation cost, oil cost, labor cost, field construction cost and sewage collection pipe network construction cost are saved, lands for building large-scale sewage treatment plants are saved, huge operating cost of a sewage treatment plant can be saved, and the pollution of toxic sewage and toxic gases generated from sewers and refuse landfills to surface water, underground water and the atmosphere can be effectively minimized or eliminated. In addition, the method provided by the invention is simple and easy to operate and has good social effects and environmental protection effects.

Description

technical field [0001] The invention relates to waste treatment, in particular to a method for synchronous treatment of domestic garbage and domestic sewage of urban and rural residents. Background technique [0002] With the acceleration of urbanization in my country, the continuous development of the national economy, the continuous improvement of people's living standards and the change of consumption habits, the amount of domestic sewage and domestic garbage of urban and rural residents continues to increase. These increasing domestic sewage and domestic garbage have seriously troubled Urban and rural residents live, and have caused serious pollution to the environment. [0003] However, my country's current overall waste disposal capacity is far from enough. Solving urban and rural waste pollution and recycling renewable resources are the lifelines of sustainable human development. At present, the methods for dealing with domestic sewage and domestic garbage of urban ...

AI Technical Summary

Problems solved by technology

The toxic sewage leaked from the domestic sewage pipe network and the toxic sewage produced by the landfill will pollute surface water and groundwater resources. The poisonous gas released from the urban sewer and landfill will pollute the atmosphere. The operation of the pipeline network and sewage treatment plants also requires a huge amount of money
