Problems solved by technology

Because industrial sludge contains toxic organic matter, heavy metals and pathogenic microorganisms, it cannot be harmlessly treated by composting
Landfill process disposal usually has a long stable period. If the landfill area is not properly selected and scientifically constructed for anti-seepage, flood control, and disaster prevention, it is easy to cause problems such as leachate pollution of groundwater, landslides, explosions, and sludge landfills. The field covers a large area. For some large cities with shortage of land resources, the practicability of sludge landfill is declining.
However, ordinary incineration will have disadvantages such as incomplete incineration due to the high moisture content of the incineration material, difficulty in incineration (combustion enhancers need to be added), incineration is not easy to control, and a large amount of dioxins will be produced after incineration to pollute the environment.

Abstract

A harmless reduction resourceful treatment process system for waste and industrial sludge is characterized by comprising a sludge tank, a dewatering module, a dewatered sludge receiving module, a dewatered sludge conveying module, a waste tank, a grab bucket mechanism, a semi-gasification incinerator module, a heat exchanger, a thermal power station and a deodorization module. The system providedby the invention has the advantages of pertinence for slightly polluted industrial sludge and waste, small occupied area, low operation energy consumption, simultaneous treatment of sludge and waste,harmlessness, reduction, recycling, and realization of reaching of national emission standards with low energy consumption.

Description

technical field [0001] The invention relates to a sludge and waste treatment process, in particular to a waste and industrial sludge harmless reduction resource treatment process system. Background technique [0002] With the continuous development of my country's industry and the continuous increase of industrial enterprises, the disposal of industrial sludge generated by industrial wastewater treatment stations is becoming a problem that large and medium-sized cities have to face. At present, sludge treatment methods include incineration, landfill and composting. Because industrial sludge contains toxic organic matter, heavy metals and pathogenic microorganisms, it cannot be harmlessly treated by composting. Landfill process disposal usually has a long stable period. If the landfill area is not properly selected and scientifically constructed for anti-seepage, flood control, and disaster prevention, it is easy to cause problems such as leachate pollution of groundwater, l...
