Description
Technical Field
The utility model relates to an environmental protection equipment technical field, more specifically the utility model relates to an industry tail water environmental protection treatment system that says so.
Background
In the production processes of mine ore dressing, sand and stone washing and the industries, a large amount of production tail water, namely sewage (waste water) containing solid and ionic compounds, is one of the important sources of the current domestic environmental hazards, and has high treatment technical difficulty and treatment cost. At present, the domestic technical schemes are various and are basically divided into three categories: (1) a technical scheme of a rake thickener and a tailing pond; (2) the technical proposal of the deep cone thickener and the belt filter press/plate frame filter; (3) the technical scheme of the multistage sedimentation tank and the belt filter press/plate and frame filter.
Wherein, the technical scheme work flow of the rake thickener and the tailing pond is as follows: tail water and a flocculating agent enter a rake thickener, solid-liquid separation is carried out after precipitation, clear water produced by overflow is recycled, and underflow (high-concentration slurry) is sent to a tailing pond for stockpiling management, so that the scheme is widely applied to treatment of mine ore dressing tail water and sand washing tail water; the working process of the scheme of the deep cone thickening barrel and the plate frame/belt type filter press is as follows: tail water and flocculating agent are sent into a deep cone thickening barrel, tail solid and flocculating agent react and crystallize, then solid and liquid are separated, clear water overflows and returns for reuse, and tail solid crystals are sent to a plate frame/belt filter press for dehydration and cake making; the working flow of the scheme of the multistage sedimentation tank and the plate frame/belt type filter press is as follows: the flocculation medicament is along with tail water sedimentation tank group, and solid phase crystallization is after deposiing step by step, and first grade, second grade flocculation crystal adopt the immersible pump sending to filter dehydration system cake, and superfine grain grade deposits at later pond bottom (being thick form) at all levels, adopts excavator or other equipment regularly to clear up, and this scheme is comparatively general in sand stone washing tail water, chemical production tail water, livestock breeding tail water, aquaculture tail water treatment.
However, the technical scheme of the rake thickener and the tailings pond has the following defects:
a. the occupied area is as follows: the system occupies a large area and the tailing pond occupies a large area;
b. construction cost: the system cost + the tailing pond cost + the land acquisition and renting + the forest seedling compensation + the safety assessment and environmental assessment cost, so the cost is high;
c. environmental protection hidden danger: the hidden environmental problems of medicament residue and particle dust emission are great;
d. potential safety hazard: hidden troubles of dam break secondary geological disasters exist;
e. the production cost is as follows: investment expropriation and amortization, system operation cost, clear water return and later-period management cost, and the treatment cost is high;
the scheme of the deep cone dense barrel and the plate frame/belt type filter press has the following defects:
a. environmental protection hidden danger: a large amount of medicament is left in mud cakes and backwater, and the backwater pollutes products;
b. the production cost is as follows: the investment expropriation and amortization, the system running cost, the clear water return and the later management cost, particularly the medicament production cost account for a large proportion;
c. production capacity: limited, not suitable for large scale treatment of tail water;
d. the manufacturing cost in the same proportion: because the capacity is limited, the cost is higher than the same ratio.
The drawbacks of the multi-stage settling tank + plate and frame/belt filter press scheme are as follows:
a. environmental protection hidden danger: the potential hazard of residual medicament in mud cakes and backwater exists, and the backwater utilizes polluted products;
b. the production cost is as follows: the medicament cost, the system operation cost and the sludge removal cost are high;
c. production capacity: limited, not suitable for large scale treatment of tail water;
d. the manufacturing cost in the same proportion: the production capacity is limited, and the cost is higher than the same ratio;
e. difficulty in micro-curing treatment: because the sediment step by step, the tail that leads to output after the second grade sediment is solid is high concentration mud form, generally adopts excavator clearance, tank car outward transportation, and mud cake transportation, stockpiling all have serious environmental protection hidden danger, and the treatment cost is on the high side.
