Embodiment Construction

[0026] Structure of the present invention sees figure 1 , 2 shown. A high-efficiency anaerobic bioreactor for treating leachate in waste incineration plants, mainly including anaerobic tank (A), water inlet system (B), return system (C), reaction system (D), water distribution system (E ), three-phase separator (F), biogas collection chamber (G), sampling system (H), water outlet system (M), on-line monitoring (N) and sludge discharge system (L).

[0027] The reaction system (D) includes a first reaction zone (D1) and a second reaction zone (D2), and the part below the lower three-phase separator (F1) to the bottom of the tank (A) is the first reaction zone (D1 ), the part between the lower three-phase separator (F1) and the upper double-layer three-phase separator (F2) is the second reaction zone (D2).

[0028] The water inlet system (B) is directly connected to the return pipe (C1). After the landfill leachate is mixed with the return effluent, it flows into the water dis...

Abstract

The invention relates to an anaerobic bioreactor for treating leachate of a waste incineration plant.The anaerobic bioreactor mainly comprises an anaerobic tank, a water distribution system, a reaction system, a biogas collecting system and a water discharge system.The anaerobic bioreactor has the advantages that landfill leachate directly flows into a reflux pipe, and struvite crystal generation of a reflux system and the water distribution system is avoided; water inflow is diluted while the ascending flow speed of the reactor is increased by the aid of internal reflux, anaerobic sludge is in an expansion state in the vertical direction, anaerobic microorganisms sufficiently contact with matrix to reach a good mass transfer effect, the organic pollutants in the leachate of the waste incineration plant are removed efficiently, volume load can reach 8-10kgCOD / m<3>.d, and COD removing rate reaches up to 85-95%; the reactor is low in energy consumption, high in gas production rate, beneficial to energy recycling, capable of achieving automatic control, simple in operation, stable and durable, short in construction period, small in floor space and capable of saving land resources, and the floor space of the reactor is about 40% of that of other anaerobic systems.

Description

technical field [0001] The invention relates to a high-efficiency anaerobic bioreactor for treating leachate of a garbage incineration plant, which belongs to the technical field of sewage biological treatment and is used for anaerobic treatment of the leachate of a garbage incineration plant. Background technique [0002] The harmless treatment of urban waste basically includes landfill, incineration, and composting. Landfill is an effective method to consume a large amount of municipal solid waste, and it is also the final disposal method for all waste treatment process residues. Its biggest feature is that the treatment cost is low and the method is simple, but it occupies a large area and is easy to cause secondary pollution of groundwater resources. The incineration method is a method in which the garbage is placed in a high-temperature furnace to fully oxidize the combustible components, and the heat generated is used for power generation and heating. The incineratio...
