Description
Technical field
The utility model relates to a kind of sewage treatment equipment, specifically a kind of mine tailing wastewater treatment system.
Background technology
Contained objectionable impurities in the mine tailing wastewater in dressing-works, derive from the flotation reagent adding in ore dressing process, metallic element in ore and soluble compound, the principal pollutant of phosphorus ore factory waste water are inorganic phosphorus, since 20 century 70s, abroad at limit phosphorus, prohibit the treatment process of developing some phosphorus-containing wastewaters in phosphorus process, as metal mold exchange of particles resin dephosphorization method, the electrolysis dephosphorization method of conversion polarity of electrode, biological dephosphorization etc., in industrial applications, abroad biological dephosphorization compared with proven technique, but its condition harshness, cost of investment is high, domestic By Bubble-floating Method requires to regulate certain hydraulic pressure air pressure, control ascent rate, operative technique difficulty is large, and it is lower to contrast the great material clearance in 1, the control of dissolved oxygen in activated sludge process, sludge age and C/P ratio definite is its key problem in technology, is difficult to control, and reverse osmosis method processing cost is high.
Utility model content
The purpose of this utility model is to provide the mine tailing wastewater treatment system that is applicable to phosphorus ore that a kind of level of automation is high, adopt the dephosphorization of coagulating sedimentation-sand filtration method, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of mine tailing wastewater treatment system, comprise connected successively equalizing tank, stirred tank, tube settler, sandfiltration pot and reuse pool, described stirred tank is connected with lime agitated pool, between described stirred tank and lime agitated pool, be provided with magnetic valve, described stirred tank is connected with flocculation agent pond, described stirred tank is provided with PH supervisory system, described PH supervisory system control electromagnetic valve switch, described tube settler is connected with sludge storage pool respectively with sandfiltration pot, described sludge storage pool is connected with sludge dewatering equipment, described reuse pool is connected with reuse pumping plant.
As further program of the utility model: described PH supervisory system adopts PLC to control.
As further scheme of the utility model: described equalizing tank arranges training wall and waterpower impeller.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts the method for coagulating sedimentation-sand filtration to remove to process phosphorite tailings waste water, take up an area less, invest little, stable and reliable operation, adopt PH supervisory system control electromagnetic valve switch, control milk of lime add-on and realize the accurate adjusting to PH in wastewater treatment process, that operation is controlled is simple, level of automation is high, remove organism and good denitrogenation and dephosphorization effect, the sludge quantity of generation is few and good stability.
Brief description of the drawings
Fig. 1 is workflow diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of mine tailing wastewater treatment system, comprise connected successively equalizing tank 1, stirred tank 2, tube settler 3, sandfiltration pot 4 and reuse pool 5, described equalizing tank 1 arranges training wall and waterpower impeller, described stirred tank 2 is connected with lime agitated pool 6, between described stirred tank 2 and lime agitated pool 6, be provided with magnetic valve 7, described stirred tank 2 is connected with flocculation agent pond 8, described stirred tank 2 is provided with PH supervisory system 9, described PH supervisory system 9 adopts PLC to control, described PH supervisory system 9 is controlled magnetic valve 7 switches, described tube settler 3 is connected with sludge storage pool 10 respectively with sandfiltration pot 4, described sludge storage pool 10 is connected with sludge dewatering equipment 11, described reuse pool 5 is connected with reuse pumping plant 12.
Principle of work of the present utility model is: phosphorite tailings waste water drains into equalizing tank 1 after collecting, water quality, the water yield are regulated, equalizing tank 1 water outlet through water pump lifting to stirred tank 2, regulate the pH value of waste water to stirred tank 2 feeding lime breasts by lime agitated pool 6, because stirred tank 2 is provided with PH supervisory system 9, the pH value of monitoring waste water in real time, after waste water pH value is up to standard, PH supervisory system 9 is sent instruction closure to magnetic valve 7, stop adding milk of lime, flocculation agent pond 8 adds CaCl to stirred tank 2 simultaneously
2with PAM compound coagulant, Pollutants in Wastewater fully reacts with coagulating agent, stirred tank 2 water outlets are most of throw out precipitation in tube settler 3, after tube settler 3 water outlets, remove remaining phosphorus and other organic pollutents in waste water through sandfiltration pot 4, purifying waste water after sand filtration drains into reuse pool 5, pumps reuse by reuse water pumping plant 12, and the mud that tube settler 3 and sandfiltration pot 4 produce stores at sludge storage pool 10, transport outward through sludge dewatering equipment 11, sludge dewatering equipment 11 is intermittent operation.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other specific form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification sheets is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should make specification sheets as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
