Abstract
The present invention discloses a kind of processing of coal mine sewage and recovery process, comprising the following steps: Step 1: sewage enters sedimentation basin, precipitates 1h-2h, in precipitation process, 70g-90g flocculant is added in every cubic metre of waste water；Step 2: extracting surface layer clear water enters biodegradable pond, Air Exposure 40min-50min；Step 3: water is passed sequentially through into active carbon and quartz sand filtration, and in filter process, coutroi velocity；Step 4: by filtered water secondary precipitation, sedimentation time 50min-60min；Step 5: secondary filter, in filter process, water flow is stirred；Step 6: sterilizing 20min-30min as at a high temperature of 120 DEG C -150 DEG C；Step 7: after cooling, discharge.The present invention makes water outlet reach Treated sewage reusing standard.
Description
Technical field
The invention belongs to water treatment fields, and in particular to a kind of processing of coal mine sewage and recovery process.
Background technique
Coal accounts for 70% or more in China's energy resource structure, and mine coal is contaminated the good underground water of original water quality,
A large amount of coal dusts, rock dust, suspended matter, artificial pollution and microorganism enter in water, and suspended matter, chemistry need in some coal mine sewages
Oxygen amount, sulfide and total hardness grade height.So largely exceeded sewage, will be to environment without processing direct emission for mine discharge
It causes seriously to pollute, while causing a large amount of wastes of water resource.Coal mine sewage is a kind of resource of preciousness, how treatment for reuse,
It does a lot of work for many years, achieves certain achievement.But the domestic processing method used is still traditional handicraft at present,
Although the technique treatment for reuse water effect is preferable, technique falls behind, and equipment, facility are complicated, and construction investment is big, and occupied area is more,
Operating cost is high, and operational administrative is inconvenient.
Summary of the invention
The technical problems to be solved by the invention are in view of the above shortcomings of the prior art, to provide at a kind of coal mine sewage
Reason and recovery process make water outlet reach Treated sewage reusing standard.
The technical scheme adopted by the invention is that: a kind of processing of coal mine sewage and recovery process, comprising the following steps:
Step 1: sewage enters sedimentation basin, 1h-2h is precipitated, in precipitation process, 70g- is added in every cubic metre of waste water
90g flocculant；
Step 2: extracting surface layer clear water enters biodegradable pond, Air Exposure 40min-50min；
Step 3: water is passed sequentially through into active carbon and quartz sand filtration, and in filter process, coutroi velocity；
Step 4: by filtered water secondary precipitation, sedimentation time 50min-60min；
Step 5: secondary filter, in filter process, water flow is stirred；
Step 6: sterilizing 20min-30min as at a high temperature of 120 DEG C -150 DEG C；
Step 7: after cooling, discharge.
In one embodiment, in step 1,90g flocculant is added in every cubic metre of waste water by sedimentation time 2h.
In one embodiment, in step 2, the Air Exposure time is 50min.
In one embodiment, in step 4, sedimentation time 60min.
In one embodiment, in step 6,30min is sterilized at a high temperature of 150 DEG C.
The beneficial effects of the present invention are: sewage rate of load condensate is high, and anti impulsion load is high, requires water inlet without limitation；Sewage
It mixes and reacts sufficiently, stable effluent quality with coagulant；Water outlet reaches Treated sewage reusing standard, can be used for fire demand water, or
It is directly used in other industrial waters such as spray of coal mine.
Specific embodiment
Below in conjunction with specific embodiment, invention is further described in detail.
A kind of processing of coal mine sewage and recovery process, comprising the following steps:
Step 1: sewage enters sedimentation basin, 1h-2h is precipitated, in precipitation process, 70g- is added in every cubic metre of waste water
90g flocculant；
Step 2: extracting surface layer clear water enters biodegradable pond, Air Exposure 40min-50min；
Step 3: water is passed sequentially through into active carbon and quartz sand filtration, and in filter process, coutroi velocity；
Step 4: by filtered water secondary precipitation, sedimentation time 50min-60min；
Step 5: secondary filter, in filter process, water flow is stirred；
Step 6: sterilizing 20min-30min as at a high temperature of 120 DEG C -150 DEG C；
Step 7: after cooling, discharge.
In the present embodiment, in step 1,90g flocculant is added in every cubic metre of waste water by sedimentation time 2h.
In the present embodiment, in step 2, the Air Exposure time is 50min.
In the present embodiment, in step 4, sedimentation time 60min.
In the present embodiment, in step 6,30min is sterilized at a high temperature of 150 DEG C.
Sewage rate of load condensate of the present invention is high, and anti impulsion load is high, requires water inlet without limitation；Sewage mixed with coagulant with it is anti-
Should sufficiently, stable effluent quality；Water outlet reaches Treated sewage reusing standard, can be used for fire demand water, or be directly used in the spray of coal mine
Other industrial waters such as leaching.
A specific embodiment of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.
