The industrial effluent sewage of earlier the mine tailing ditch being collected is stored in the sewage lagoon; Then the sewage in the sewage lagoon is sent into and carried out preliminary sedimentation in the inclined-plate clarifying basin, and the clear water above the inclined-plate clarifying basin of post precipitation is recycled, the sewage of below is sent in the concentration basin; Then in concentration basin, add the sewage disposal medicament, make itself and sewage thorough mixing, continue then to precipitate; Then the clear water above the concentration basin of post precipitation is reclaimed, the sewage of below is sent into carried out the press filtration processing in the pressure filter.
Further be when in concentration basin, adding medicament, to be that the bottom from concentration basin adds.
The optimal way of such scheme is, when the concentration basin bottom adds medicament, is to finish by the drug feeding pipeline that is laid on the concentration basin bottom.
Further be that the sedimentation time behind the sewage addition agent medicine in concentration basin is 30～40 minutes.
Further be that the sewage in the sewage lagoon is sent in the inclined-plate clarifying basin by sump pump; Sewage in the inclined-plate clarifying basin is sent in the concentration basin by the thrust-augmenting nozzle of bottom, pond; Sewage in the concentration basin is delivered in the pressure filter by the slag stock pump, and clear water is sent in the sewage lagoon by the upflow tube on top.
The invention has the beneficial effects as follows: by adding the operation of sewage disposal medicament originally at the mine tailing ditch, change into and in concentration basin, add the sewage disposal medicament again, thereby make a large amount of suspended substances and the impurity that contain in the sewage by inclined-plate clarifying basin post precipitation input concentration basin, can in concentration basin, be handled to greatest extent and be condensed, and finally precipitate, concentration basin is really played concentrate the suspended substance in the sewage and the effect of impurity, improve the suspended substance in the sewage after concentrated and the content of impurity simultaneously, for the suppressing filter of postorder saves time, raise the efficiency.After the clear water of concentration basin top reclaims, can reduce a large amount of excessive moistures, reduce the loss of filter plate the washing away of the filter plate of pressure filter.In addition, because the sewage disposal medicament just adds in concentration basin, like this, suspended substance and the impurity in the sewage is concentrated in inclined-plate clarifying basin, the agglomerative comparatively small amt, so precipitation, the amount of piling up are also less in inclined-plate clarifying basin, prolonged blocked and time of clearing up of inclined-plate clarifying basin.
