A resource recycling system for all underground sewage and solid waste in a residential area

Abstract

The invention relates to a resource recycling system for all underground sewage and solid waste in a residential area, which is characterized in that it includes a membrane enrichment unit, a garbage pretreatment system, and a supercritical reaction system arranged under the ground. The sewage treatment pool, garbage storage pool on the second floor, and the control system installed in the central control room on the ground. The control system includes sensors, on-site execution components, controllers, and upper computers. The on-site execution components are electrically connected to the controller. Sensors, controllers Signal connection with the host computer; sensors and on-site execution components are set on the oxidant delivery pipeline, fuel delivery pipeline, material delivery pipeline, reactor, gaseous product discharge unit, and liquid product discharge unit. The invention can treat sewage and solid waste at the same time, so that solid waste is no longer treated by incineration, reducing pollutant discharge, and realizes the control process of system start, stop, emergency stop process, temperature adjustment and pressure adjustment through the control unit, and the system runs The generated data 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
