Abstract
The present invention relates to a kind of waste water treatment method for asbestos, comprise the steps: the asbestos wastewater that compiles in the pond is transported in the horizontal screw centrifuge, after the horizontal screw centrifuge high-speed separation, still the parting liquid that contains the small portion of residual asbestos flows into medial launder, isolated drystone cotton is discharged by horizontal screw centrifuge, and collects.Parting liquid in the medial launder is transported in the settling tank, through for some time post precipitation, discharge clear water from the top of settling tank, the asbestos mud concentrated solution of discharging from the bottom of settling tank is transported to and compiles the pond, mix with untreated asbestos wastewater, carry out next round by horizontal screw centrifuge and handle.
Description
The present invention relates to a kind of asbestos separation method of asbestos wastewater.
At present, all wet methods use the industrial and mining enterprises of asbestos or wet method manufacturing asbestos products all can produce the asbestos wastewater of contaminate environment.Generally adopt simple natural sedimentation method to handle now, wherein a part of asbestos slightly precipitate, and another part still is suspended in the water, the part that suspends focuses on after relying on artificial salvaging to dry, handled waste water still contains the asbestos of part, because of asbestos are a kind of carcinogenss, will bigger harm and contaminate environment be arranged to human body as discharging.In addition, the settling tank floor space is big, the operation site environment is poor, labor strength is big.
The object of the present invention is to provide a kind of method, solve the asbestos wastewater pollution problems with the mechanical treatment asbestos wastewater.
1. technical scheme of the present invention comprises the steps:. the asbestos wastewater that compiles in the pond is transported in the horizontal screw centrifuge, after the horizontal screw centrifuge high-speed separation, still the parting liquid that contains the small portion of residual asbestos flows into medial launder, and isolated drystone cotton is discharged by horizontal screw centrifuge, and collects.2.. the parting liquid in the medial launder is transported in the settling tank, through for some time post precipitation, discharge clear water from the top of settling tank, the asbestos mud concentrated solution of discharging from the bottom of settling tank is transported to and compiles the pond, mix with untreated asbestos wastewater, carry out the processing of next round again by horizontal screw centrifuge.
The present invention compared with prior art has following advantage:
(1) can be used as service water through the water of settling tank top discharging and recycle, do not have sewage discharge and can a large amount of water saving.
(2) carry out roughing out with horizontal screw centrifuge, can reduce labor intensity.
(3) can remove carcinogens asbestos wool in the waste water up hill and dale.
The invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing is the relevant devices connection diagram when of the present invention for using
After 1 injection of untreated asbestos wastewater compiles pond 9, asbestos wastewater is transported in the horizontal screw centrifuge (full name is a horizontal spiral discharge sedimentation centrifuge) 4 through pipeline with pump 2, carry out high-speed separation by horizontal screw centrifuge 4, isolated drystone cotton falls into collecting cart 7, and the parting liquid that contains a small amount of remaining asbestos of discharging through horizontal screw centrifuge 4 flows in the medial launder 8, use again pump 3 through pipe-line transportation in settling tank 5, post precipitation through for some time (for example about two hours), asbestos mud concentrated solution all concentrates on the bottom of settling tank 5, open by-pass valve control, asbestos mud concentrated solution just relies on the pressure of top clear water to be back to compile in the pond 9, mix with the asbestos wastewater of handling without horizontal screw centrifuge 41, continuing into, horizontal screw centrifuge 4 carries out the processing of next round.And the water 6 of discharging through settling tank 5 tops can be used as process water and recycles.Settling tank 5 bottoms are done tapered, are beneficial to the precipitation and the discharging of asbestos mud.
Claims (2)
- A kind of waste water treatment method for asbestos comprises the steps:1, the asbestos wastewater 1 that compiles in the pond 9 is transported in the horizontal screw centrifuge 4, after horizontal screw centrifuge 4 high-speed separation, the parting liquid that still contains the small portion of residual asbestos flows into medial launder 8, and isolated drystone cotton is discharged by horizontal screw centrifuge 4, and collects.
- 2, the parting liquid in the medial launder 8 is transported in the settling tank 5, through for some time post precipitation, discharge clear water 6 from the top of settling tank 5, the asbestos mud concentrated solution of discharging from the bottom of settling tank 5 is transported to and compiles the pond 9, mix with untreated asbestos wastewater 1, carry out next round by horizontal screw centrifuge 4 and handle.
