Description
Technical field
The present invention relates to one kind to realize solid-liquid concentration, separated cleaning equipment and method, belongs to sewage disposal device technology
Field.
Background technology
In mine, metallurgy, micro mist, chemical process, substantial amounts of slag inclusion waste water can be produced, wherein proportion is larger consolidates
It can mutually be removed by precipitation, but proportion is very difficult to remove compared with light, the less solid suspension thing of particle diameter, causes the pollution of water body.
Industrial wastewater containing a large amount of solid suspension things, such as coal washing waste water, micro mist industry production slurries, titanium white production
Waste water etc., wherein containing large quantities of lightweight suspension things, serious pollution is caused to environment neighbouring around plant area.Wherein, wash
Coal waste water has been one of primary pollution source of coal industry, is increasingly valued by people.The common feature of these waste water is
Suspended matter is especially firm, stand some months will not natural subsidence, therefore handle it is very difficult.Without any appropriate processing
Under conditions of be discharged into external environment, the safety of surface water, underground water and geomorphological environment will undoubtedly be damaged.
To realize the processing or reuse up to standard of waste water, it usually needs set huge flocculation, precipitation, filtration system, take up an area
Area is huge, and operational effect is undesirable and operating cost is higher.
At present, the processing method to such water is closed cycle method, and this method possesses strong in emission reduction and recycling water utilization
Big advantage.But a large amount of suspended matters cannot be removed thoroughly during the progressively recycling of water so that aqueous suspension concentration
It is higher and higher, circulating effect is not only influenced, halt production is also resulted in when serious.The suspended matter in water is largely to have recycling at the same time
The material of value, there is very big economic value.Often because Recovering equipment is imperfect, so that resource loss is caused, wave
Take clear water, pollute environment.Therefore, realize that the closed cycle of such water and increase material recycle possess special tactful meaning.
Largely take that " primary sedimentation tank-PH regulating reservoirs-dosing flocculation basin-precipitation is dense for the treatment process to such water
The treatment process of contracting pond-secondary settling tank (filter press or the concentration of other filter plants)-clear water reserviors ".But this technological requirement has
Enough capacity and the sedimentation basin of number are (such as：PH is adjusted, dosing pond, flocculation sediment etc.), take up a large area, the process time is long, fortune
Row is costly, and the salt content in increasing water during dosing, increases the processing cost of subsequent treatment.Summary is got off,
It is primarily present following problem：1st, wherein most bulky grain suspended matters can only be removed, other fine suspension things can not remove, and
Repetitive cycling is progressively saved bit by bit in system, causes Circulation water density to increase the vicious circle that interacts reduced with thickening efficiency；2、
The hydrologic(al) budget of recycling is difficult to control, and closed cycle can not be realized, it is necessary to send a large amount of tail water to some other department, pollutes environment；3rd, processing is set
It is standby huge, it is various, take up a large area；4th, operating cost is high.
