Community full underground type resource cyclic utilization system for sewage and solid trash

Abstract

The invention relates to a community full underground type resource cyclic utilization system for sewage and solid trash. The community full underground type resource cyclic utilization system is characterized by comprising a membrane enrichment unit, a trash pretreatment system and a supercritical reaction system which are arranged on the first floor underground, a sewage treatment pool and a trash storage pool which are arranged on the second floor underground, and a control system arranged in a ground central control room; the control system comprises sensors, on-site execution parts, a controller and an upper computer; the on-site execution part is electrically connected with the controller; the sensor, the controller and the upper computer are in signal connection; the sensors and the on-site execution parts are arranged on an oxidizing agent conveying pipeline, a fuel conveying pipeline, a material conveying pipeline, a reactor, a gas-stage product discharge unit and a liquid-stage product discharge unit. The community full underground type resource cyclic utilization system can treat sewage and solid trash at the same time, solid trash is not treated through incineration any more, pollutant discharge is reduced, the control processes such as start, stop, emergency stop, temperature regulation and pressure regulation of the system are achieved through a control unit, and data generated when the system runs can be effectively collected, stored and analyzed.

Description

technical field [0001] The invention belongs to the fields of sewage, solid waste treatment and resource energy recycling, and in particular relates to a resource recycling system for fully underground sewage and solid waste in a residential area. Background technique [0002] At present, people are beginning to pay more and more attention to the pollution control of urban solid waste, and put forward the policy of "reduction, recycling, and harmlessness". In the past, common waste disposal methods were collected and sent to landfills, or incinerated Furnace incineration. But both of them will cause environmental protection problems. Improper disposal of garbage in landfills will pollute groundwater and be accompanied by stench. Moreover, the area available for landfills in many cities has become less and less. Incineration inevitably produces toxic gases that harm living organisms. However, the solid waste in the community has high moisture content, low calorific value, h...

Problems solved by technology

[0005] The present invention aims at the problem that the existing sewage and garbage cannot be treated at the same time, and provides a resource recycling system based on supercritical water oxidation technology for the community, which can simultaneously treat sewage and solid garbage, so that the solid garbage is no longer processed by incineration. Reduce pollutant emissions; at the same time, convert the produced supercritical water and supercritical gas into resources such as steam or hot water for recycling to obtain considerable economic benefits, and implement automatic control through the control system to realize data collection, Storage and analysis, provide reliable basis for system process adjustment and optimization, and provide necessary conditions for stable, safe and reliable operation of the system
