Description
Technical field
The utility model relates to ultra's processing technology field such as surface water, Technique of Coal Mine Drainage, refers to especially a kind of High Turbidity Water film processing system.
Background technology
Current China ultra, as the processing of surface water, Technique of Coal Mine Drainage etc., the main flow technique of employing is mostly as follows:
Ultra enters equalizing tank, by pump delivery, to coagulative precipitation tank, flocculating agent feeding device and coagulant aids throwing device is set respectively on its transport pipe, adds flocculation agent and coagulant aids respectively in the ultra in transport pipe.
Suspended particulates loss of stability after input flocculation agent in water, the mutual coagulation of micelle thing phase increases particulate, forms flocs unit, and flocs unit is grown up and can under action of gravity, depart from aqueous phase precipitation after certain volume, thereby removes a large amount of suspended substances in water.
In addition, in order to shorten the sedimentation time of suspended particulates in water, add coagulant aids, coagulant aids, by the further polymerization of flocs unit forming, forms larger flocs unit, accelerates to realize the speed of solid-liquid separation.
Water after solid-liquid separation enters intermediate pool, sludge settling is to the mud receiving tank at the bottom of coagulative precipitation tank pond, the mud of collecting in mud receiving tank is further delivered to sludge thickener by sludge pump, and mud is regularly processed rear mud cake by dehydration equipment and transported outward, and the water of separating out is back in equalizing tank.

There is following several respects problem in above-mentioned ultra's treatment process:
1, effluent quality is unstable
To be the absorption that relies on filtrate remove solid particulate in water with interception to more medium filter, when strainer just moves, filter membrane in the middle of filtering material particle not yet forms, and some less particles will enter in clean water basin by strainer, cause the water body in clean water basin to have turbidity and naked eyes visible particle thing.
2, water body is had to secondary pollution
Flocculation agent generally adopts polymerize aluminum chloride, in country < < drinking water sanitary standard > > (GB5749-2006), clearly the aluminum ion in regulation water can not be greater than 0.2 mg/litre, the excessive absorption aluminium of human body can cause various diseases, such as senile dementia etc.Coagulant aids generally adopts polyacrylamide, and poly-the third vinyl-amine solution has micro-toxicity, to human body, also can damage.Therefore, adopt flocculation agent and coagulant aids treated water to be secondary polluted.
3, use in a large number flocculation agent and coagulant aids, cause water treatment running cost high
Water treatment plant's one ton of water of every processing need to consume flocculation agent and coagulant aids each 50～100g, wherein 0.0018～0.0026 yuan every gram of flocculation agent, 0.008～0.02 yuan every gram of coagulant aids.Getting an intermediate value calculating ton cost of water treatment is 0.0022 * 75+0.014 * 75=1.215 unit.
