The present invention relates to the treatment process of solid-liquid separation in a kind of sewage, particularly the solid-liquid separation treatment process of the sewage that produced of mining site washup.
Background technology
CN93115714.5, the Chinese invention patent that name is called " a kind of treatment method for coal washing water " discloses a kind of treatment method for coal washing water, it is that the coal washing water of earlier coal washery being discharged makes the coal slime of greater particle size precipitate in slurry pond, the coal washing water that the upper strata is overflowed is transferred to 6.0～7.5 to pH value with acid in the pH value equalizing tank again, then the coal washing water that mixes up pH value earlier after two-stage flyash filtering basin filter, to purify coal washing water.The three layer filtration medium is arranged in the flyash filtering basin, and the upper strata is a river sand, and the middle level is a flyash, lower floor is a cobble, and the coal washing water suspension content after the processing is less than 300mg/L, and COD is less than 150mg/L, pH value 6～9, the water after the purification can discharge, and also can be reused for coal washing.But the disclosed method of this invention deals with very trouble, and the input cost height, and purification cycle is long.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple, and is with low cost, the sewage water treatment method that purification cycle is short.
Sewage water treatment method of the present invention may further comprise the steps:
A. drop into precipitation agent at the sewage outlet place;
B. after precipitation agent was sneaked into sewage, settlement of sewage flowed into the settling tank of at least three trapezoidal arrangements successively;
C. pass through the settling tank post precipitation, clear water flows into clean water basin, and the water of clean water basin uses by being pumped back to the production line cocycle;
D. the throw out in the settling tank is introduced reservoir;
E. the throw out of reservoir is sent by pumping to the dehydrating press processed;
F. the clear water that obtains after the processed flows into clean water basin.
Precipitation agent described in the above-mentioned steps a is a lime.
For realizing that treatment process of the present invention adopts following waste disposal plant, this device is made up of settling tank, clean water basin, reservoir, dehydrating press and pump, at least three settling tank is trapezoidal arrangement successively, clean water basin and reservoir are positioned at least significant end and separate, clean water basin are connected with dehydrating press with production line by pipeline respectively with reservoir, pump respectively with pipe connection.
Described settling tank, in the one side lead is arranged, and be communicated with settling tank respectively, opposite side at settling tank also has lead, and water outlet is arranged on the pool wall, and lead is isolated into independent grooves by water outlet, water outlet is communicated with reservoir by groove, described water outlet has valve, and described valve is combined by 2-9 piece division board, and is separate between the every division board.
Sewage water treatment method of the present invention, when sewage when sewage outlet flows out, throw in precipitation agent, flow into settling tank subsequently, settling tank is trapezoidal arrangement from high to low successively, making sewage to flow into successively in each settling tank from high to low precipitates, to strengthen sedimentation effect, water outlet on the settling tank pool wall is provided with valve, valve combines for the polylith division board, made things convenient for the throw out in the settling tank has been cleared up, the present invention can make sewage just realize solid-liquid separation in process of flowing, water in the inflow clean water basin has reached the standard of cycling and reutilization, clear water in the clean water basin returns from pipeline by pump and is fed to washup line continuation use, realized the utilization again of water resources, sewage water treatment method of the present invention and apparatus structure are simple, can realize processing at normal temperatures and pressures to sewage, laid down cost is cheap, and the precipitation cycle is short, effect is obvious, and institute's treated water can be recycled on the washup line, has saved precious water resource, and environment is not produced pollution, and the present invention can be widely used in the colliery, in the solid-liquid separation after the cleaning in ore deposits such as plumbous zinc ore.
Description of drawings
Fig. 1 is a waste disposal plant structural representation of the present invention.
Among the figure, 1-sewage outlet, 2-settling tank, 3-clean water basin, 4-reservoir, 5-dehydrating press, 6-pump, 7-pipeline, 8-lead, 9-groove, 10-valve, 11-washup line.
Embodiment
The invention will be further described below in conjunction with accompanying drawing, but be not limited to embodiment.
Embodiment 1
Waste disposal plant of the present invention, this device is by settling tank 2, clean water basin 3, reservoir 4, dehydrating press 5 and pump 6 are formed, at least three settling tank is trapezoidal arrangement successively, settling tank 2 can be brick mix structure, its volume can be decided according to the actual needs, a plurality of settling tanks can make sewage be precipitated fully in flow process, improve the effect of solid-liquid separation, settling tank 2 is trapezoidal arrangement from high to low successively, comply with the principle that Water seeks its own level, make sewage flow into settling tank after sewage outlet 1 and precipitant mix, precipitation agent can make the general precipitation agent of industry, such as: lime.Throw in precipitation agent, can accelerate the sedimentation speed of mineral in the water, improve sedimentation effect, the precipitation agent of being thrown in is a lime, its cost is low, sedimentation effect is obvious, and can not produce harm to environment, sewage is trickling from top to bottom naturally between settling tank, do not need additionally to provide power, saved resource, settling tank 2 one sides have lead 8, and be communicated with settling tank 2 respectively, opposite side at settling tank 2 also has lead, water outlet is arranged on the pool wall, lead is isolated into independent grooves by water outlet, water outlet is communicated with reservoir 4 by groove 9, described water outlet has valve 10, described valve 10 is combined by 2-9 piece division board, separate between the every division board, when Open valve, with one one order of division board breakdown, when the precipitation logistics in the pond finishes closing valve 10, get final product with the space between water proof materials such as the plastic cloth sealing division board after order is installed again with division board, convenient and easy, lead is positioned on the sidewall of settling tank, and be communicated with settling tank 2 respectively, in the time will clearing up to the throw out in one of them settling tank, can directly introduce sewage in the settling tank of not cleaning by sewage outlet 1, and do not influence normal activity in production, when cleaning is positioned at the intermediary settling tank, then the sewage that will precipitate by the lead on another sidewall 8 is incorporated in the next settling tank again and further precipitates, in running order all the time to guarantee treatment unit, do not influence the normal operation of production line, water outlet on the settling tank pool wall is provided with valve, valve combines for the polylith division board, in the time need clearing up to the throw out in the settling tank, division board can be taken out successively, open the valve 10 of water outlet, making throw out pass through groove 9 trickles in reservoir 4, after cleaning out, division board is installed successively, can precipitate sewage once more after the sealing, can clear up the throw out in the pond so easily, the throw out that flows in the reservoir carries out processed by pump from pipeline 7 injection dehydrating presses 5, the clear water of gained is back in the clean water basin 3 in the processed process, clear water in the clean water basin 3 is fed to washup line 11 by pump for 7 times from pipeline to be continued to use, realized the utilization again of water resources, and can not exert an influence to environment, collect the ore deposit after dewatering, also can utilize once more.
