Resourceful treatment system for municipal domestic wastewater and organic waste

Abstract

The invention discloses a resourceful treatment system for municipal domestic wastewater and organic waste. The resourceful treatment system is characterized by comprising a kitchen waste vacuum collecting system, a sold-liquid separating device, a wastewater homogenizing tank, an organic solid waste homogenizing tank, a wastewater anaerobic reactor and a solid anaerobic reactor, wherein a first inlet of the solid-liquid separating device is communicated with an outlet of the kitchen waste vacuum collecting system, and a second inlet of the solid-liquid separating device is communicated with an outlet of a livestock and poultry breeding wastewater conveying pipeline; a first inlet of the wastewater homogenizing tank is communicated with a domestic wastewater conveying pipeline, and a second inlet of the wastewater homogenizing tank is communicated with a liquid separating outlet of the solid-liquid separating device; a solid separating outlet of the solid-liquid separating device is communicated with an inlet of the organic solid waste homogenizing tank; an outlet of the organic solid waste homogenizing tank is communicated with an inlet of the solid anaerobic rector; an outlet of the wastewater homogenizing tank is communicated with an inlet of the wastewater anaerobic reactor. The resourceful treatment system has the advantages of being low in construction and investment cost.

Description

technical field [0001] The invention relates to a resource treatment system for urban domestic sewage and organic waste. Background technique [0002] With the rapid development of my country's economy, people's living standards and the quality of living environment have been greatly improved. However, the economic development of most towns and villages in my country lags behind that of cities. The construction of public infrastructure and services is weak and single. Many towns and The production and living environment in rural areas is poor. In order to speed up the modernization process of our society and realize the Chinese dream of the great rejuvenation of the Chinese nation, the state has begun to vigorously support the construction of new urbanization, improve the production and living environment in towns and villages, improve public infrastructure and services, and promote the urbanization of towns and villages. advance. [0003] my country's small and medium-size...

AI Technical Summary

Problems solved by technology

[0003] my country's small and medium-sized towns, rural areas, and urban suburbs have the following problems due to factors such as economics and geographical location: 1. Poor urban and rural planning, lack of public infrastructure and services, and no construction of domestic sewage, garbage collection and treatment facilities, domestic sewage 1. Garbage has not been collected and treated effectively, leading to local environmental pollution problems; 2. Centralized gas, heating, and hot water supply construction is backward, especially in rural areas, where household-based independent heating and heating have low energy utilization efficiency and air pollution. serious problems; 3 urban and rural aquaculture produces a large amount of poultry manure, due to the lack of effective management and disposal, exacerbated the problem of rural environmental pollution

The waste incineration method requires a large investment and a long period of capital occupation, which puts great economic pressure on small and medium-sized cities and towns. Moreover, if the waste gas generated by waste incineration is not properly disposed of, it is easy to cause secondary pollution

It only involves the treatment process and does not involve the collection methods of domestic waste and sewage, as well as the regeneration and utilization of water and other resources

[0006] Moreover, the above two patent applications for inventions did not involve the treatment and disposal of farming wastewater or poultry manure, which are seriously polluted in rural areas
