Abstract
The invention relates to a novel process for treating wastewater of coal mines, comprising the following steps of: making the wastewater enter a regulating basin and an aeration basin through a fence, aerating sewage in the aeration basin by using an aerator, then making the sewage enter a new sedimentation basin and a multi-stage sedimentation basin for sewage sedimentation; making the settled sewage enter a sludge collecting basin through a sludge sedimentation tank, discharging clean water in a final-stage sedimentation basin into a clean water basin, and carrying out sedimentation in the clean water basin through inclined tube sedimentation to also discharge the sludge generated by inclined tube sedimentation into the sludge collecting basin; and pumping the sewage in the sludge collecting basin to the regulating basin by using a pump to circulate, and then removing the sludge in the sludge collecting basin. According to the actual and social long-term demands of medium and small-size mine enterprises, the novel process for treating wastewater of coal mines reduces or avoids the investment of different equipment under the condition of fully meeting the requirement of environmental protection, reduces investment on the premise of meeting each index of environmental protection, and reduces the investment by about 50% compared with the traditional process.
Description
Technical field:
The present invention relates to the technical field of Industrial Wastewater Treatment, relate in particular to waste water of mine and handle brand-new technology
Background technology:
Contrast the relative merits of its technical scheme with prior art or product: to the waste water of mine complex treatment process, carry out sedimentation and filtration to waste water by 14 procedures and disinfect,, be below Gu the used equipment of disposing of sewage is also many than novel process:
The old and new's sewage treatment equipment configuration synopsis
2, investment contrast:
To produce 2000 waste water of mine treatment project daily is example:
The tradition construction costs is about: (do not contain civil engineering) about 600,000 yuan;
Waste water of mine New Process for Treatment the highest about 300,000 yuan (containing general civil engineering)
3, technology is simple: the contrast of the old and new's waste water treatment process:
(1), must the metering of supporting at least three cover electronic flows count in the above technology;
(2), above process equipment manipulation personnel electronic technology competency profiling is than higher, the personnel operation of above educational background of skill or special training in the minimum requirement.
Two kinds of technology comparative illustration:
In the tradition mine coal-cutting waste water treatment process, the main material of input is based on steel and moulding electrical equipment, though can reach environmental requirement, weak point has:
Personnel's technical ability to the operation of grasp equipment is had relatively high expectations, and need possess corresponding electrical equipment knowledge;
After the equipment operation surpasses certain time limit, in time repair, will influence facility and normally move, the phenomenon that causes sewage to be untreated and to discharge in case break down;
Because main material is based on metal, after using certain time limit because expose to the sun and rain, factor such as corrosion, metal reacts, and generates oxide compound, and environment is caused secondary pollution.
Summary of the invention:
The object of the present invention is to provide a kind of novel process for treating wastewater of coal mines, satisfying under the prerequisite of every environmental protection index, go up 14 original procedures and reduce to 6 procedures, waste water enters equalizing tank by grille well, through flowing into heavy pond, multi stage precipitation behind the quick-fried gas in aeration tank, clear water flows into clean water basin, equalizing tank, how new heavy pond enters sludge sump through sedimentary mud by sludge settling groove and blowdown in the heavy pond, and mud is discharged.
Adopt the beneficial effect of the technical program to be:
Novel process for treating wastewater of coal mines is actual and social long-range demand according to middle-size and small-size bargh, under the situation that fully satisfies environmental requirement, reduce or avoid the input of various kinds of equipment, reduce investment under the prerequisite that satisfies the every index of environmental protection, the contrast of the old and new's technology reduces investment about 50%.

Fig. 2 is the technological process block-diagram of novel process for treating wastewater of coal mines
Embodiment
Novel process for treating wastewater of coal mines of the present invention, the contrast accompanying drawing is further described its embodiment:
The waste water that coal mine produced is handled by 6 procedures, just can reach to the every index request of environmental protection, sewage flows into the aeration tank, go into a grade settling tank through set fence well stream, again in tube settler and equalizing tank, mud is gone into sewage collecting pool by the sludge settling concentrated flow, and clear water is discharged through the clean water basin effluent trough.
Processing Equipment is simple, compact construction, and equipment is less, and it is in service that need are specially from post, and use cost is extremely low.
Claims (1)
1. novel process for treating wastewater of coal mines, it is characterized in that: its technical process is: waste water enters equalizing tank and aeration tank through the fence well, with aerator the sewage in the aeration tank is carried out aeration, enter again and carry out settlement of sewage in new settling tank and the multifeed clarifier, the mud of post precipitation enters the mud collecting tank by the sludge settling groove, the clear water of level settling tank does not enter clean water basin, the mud that precipitates once more tube settling by tube settling in the clean water basin also enters in the mud collecting tank, sewage in the mud collecting tank is evacuated in the equalizing tank by pump and circulates, and the mud in the mud collecting tank is removed.
