Description
Technical field
The present invention relates to the processing method of a kind of waste water, particularly relate to the melted flying dust Heat Treatment rubbish of a kind of utilization and ooze
The processing method that filtrate is film filtration concentrated.
Background technology
Domestic waste, crop material, municipal sludge generation amount big, coverage is wide, it has also become seriously restrict me
One of key factor that society of state, economic heath develop.At present, the generation amount of National urban house refuse be up to 1.6 hundred million tons/
Year, and just increase year by year with the speed of 5%-8%.Use incineration technology to process domestic waste, make rubbish owing to having
The minimizing of limits, the advantage such as the resource of the minimum innoxious and heat energy utilization polluted, the most gradually rise.According to not
Adding up completely, current domestic existing nearly 100 garbage incinerating power plants in succession put into construction and run, and in the five-year, China is also
By solid waste burning power plants such as newly-built more than 300 seat rubbish, mud and straws.
Incineration of refuse flyash is the powdery refuse collected after the reacted tower of flue gas of refuse burning and sack cleaner purify, main
Wanting composition is the oxide containing Si, Ca, Al, Fe and calcium salt etc., possibly together with a small amount of heavy metal of activated carbon adsorption and trace
The severe toxicity Organic substance such as dioxin, belongs to the danger wastes that composition is more complicated, it is necessary to carry out safe place by relative national standards regulation
Put, and destroying completely of dioxin to be guaranteed is fixed with the effective of heavy metal, it is ensured that secondary pollution will not be produced.Safe disposal
Incineration of refuse flyash is the most all a difficult problem of environmental protection, common solidification land-fill method not only still suffer from potential safety hazard but also
Needs take a large amount of soil, and by comparison, arc melting technique can make flying dust remelted and discharge liquid slag, and liquid slag is through swashing
Form the most innoxious vitreous body material after cold, both can thoroughly eliminate safe hidden trouble, building materialsization can be realized again and utilize, just be subject to
The most how the extensive concern of industry all circles also obtains Demonstration Application.
Percolate is that the high concentration of a kind of complicated component that rubbish produces in receiving fortune, process and disposal process is organic
Waste water, not only contains a large amount of organic pollution, and ammonia nitrogen and salt content is the highest, and containing tens metal ion species, raw
Thing nutritive proportion is lacked of proper care, and water quantity and quality changes greatly, and colourity is deep and foul smelling, it is difficult to process.For reaching strict discharge standard, rubbish
The process of rubbish percolate have employed " pretreatment+biological treatment+bi-membrane method (NF+RO) " combined treatment process more.This combination
Process technique and become the prevailing technology of China's landfill leachate treatment, solve the material of contained a large amount of difficult degradations in percolate
With the advanced treating problem of toxicant, outlet effect is good, floor space is little.But, the method still can produce in a large number (30% left side
Right) film filtration concentrated, the wherein Organic substance of enriched difficult degradation, inorganic salts and micro heavy, it is difficult to process.
Current domestic more recharging to refuse landfill or return and be sprayed onto incinerator, passage in time causes the incinerator blowing-ouf of lines, fills out
Bury an infiltration liquid difficult degradation organic matter accumulation, salinity increases, until related system cannot run.
Summary of the invention
The present invention solves that technical problem present in known technology provides a kind of rubbish percolation liquid membrane filtering and concentrating liquid
Processing method, use the method can solve simultaneously incineration of refuse flyash film filtration concentrated with percolate process disposal ask
Topic, it is achieved multiple pollutant is collaborative to be processed.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of percolate
Film filtration concentrated processing method, uses rubbish percolation liquid membrane filtering and concentrating liquid Quench to melt in negative pressure reaction to fire tank and flies
Ash, the film filtration concentrated evaporation gasification heel row of being heated of percolate goes out negative pressure reaction to fire tank, and sends into incinerator
Carrying out harmless treatment, it is brilliant that melted flying dust becomes granular black glassization after rubbish percolation liquid membrane filtering and concentrating liquid cools down
Body, is deposited on negative pressure reaction to fire pot bottom；After question response, remove the tank bottoms product in negative pressure reaction to fire tank.
Described negative pressure reaction to fire tank is provided with tank body, seals lid and slag tapping equipment, is provided with described at the top of described tank body
Seal lid, the sidewall of described tank body be provided with melted flying dust entrance, concentrated solution import and air-vent, described concentrated solution import and
Described air-vent is positioned at the top of described tank body, and described melted flying dust entrance is positioned at the middle part of described tank body, described melted flying dust
Entrance is obliquely installed, and is provided with sewage draining exit in the bottom of described tank body, is provided with described slag tapping equipment in described tank body.
Described slag tapping equipment is provided with round tray and shadoof, and the lower end of described shadoof is vertically fixed on the upper of described round tray
Face center, described round tray puts off the bottom at described tank body in consistent manner, is provided with suspension ring in the upper end of described shadoof.
The inclination angle of described melted flying dust entrance is 60 °.
Described air-vent is horizontally disposed, and is arranged separately at the both sides of described tank body with described melted flying dust entrance.
Described tank body under little big cone column.
The present invention has the advantage that with good effect: utilize danger wastes incineration of refuse flyash high-temperature fusion without
During evilization, the waste heat evaporation process percolate of generation is film filtration concentrated, both can ensure that the quick of melted flying dust
Cooling molding, using water wisely, solve again a harmless treatment difficult problem for rubbish percolation liquid membrane filtering and concentrating liquid, the treatment of wastes with processes of wastes against one another, reality
Existing multiple pollutant is collaborative to be processed, and achieves many things at one stroke.And the present invention has, and flow process is simple, device therefor is simple and compact for structure, account for
Plurality of advantages, environmental benefit and the remarkable in economical benefits such as ground area is little, small investment, operational efficiency are high.
