Brief description of the drawings
Fig. 1 is the structure diagram for the house refuse pollutant treatment system that the specific embodiment of the invention provides.
Embodiment
Further illustrate technical scheme below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, dotted line is expressed as flue in figure, solid line is expressed as pipeline, and the present embodiment provides one kind to live
Garbage, waste-water exhaust treatment system, including rubbish bunker 1, pyrolysis gasification furnace 2, heat exchanger 3, cyclone dust collectors 4, level-one spray
Tower 5, two level spray column 6, waste water purification device 7 and chimney 8.
Pyrolysis gasification furnace 2, heat exchanger 3, cyclone dust collectors 4, level-one spray column 5, two level spray column 6 and chimney 8 are successively
Connected by flue, be provided with rubbish bunker 1 and ooze drip plate 9, oozed and offer weepage holes, rubbish bunker 1, heat exchange on drip plate 9
Device 3, cyclone dust collectors 4, each bottom of level-one spray column 5 and two level spray column 6 import waste water purification device by pipeline respectively
7, it is back to level-one spray column 5, two after 7 purified liquid of waste water purification device is tuned into lye by pH automatic controllers 10
Level spray column 6, two-stage spray washing being capable of effectively dedusting, deacidifications.
Waste water purification device 7 includes materialized pretreatment pond and the biochemical treatment tank being connected, and is also set up in biochemical treatment tank
There are MBR membrane bioreactors, the inlet pipe of waste water purification device 7 is connected with materialized pretreatment pond, and waste water purification device 7 goes out
Liquid pipeline is connected with the outlet of MBR membrane bioreactors.Overflow mechanism is additionally provided with waste water purification device 7, due to percolate
Constantly enter, for liquid unnecessary in regular discharge system.
Rubbish in rubbish bunker 1 is sent into pyrolysis gasification furnace 2 by grab bucket 14 of driving a vehicle.
Heat exchanger 3 is separately connected to water tank 11 and circulating pump 12 forms circulating cooling water route, takes away the heat in exhaust gas, protects
