2) waterways, working-yard is caused the primary sedimentation basin top in pond and be communicated with to form the sewage water inlet with it, nigh municipal drainage well adopts builds ditch or pipe laying is communicated with formation clear water water outlet with the clean water basin top, and Accrete clearing device, secondary Accrete clearing device are installed respectively in the bottom of primary sedimentation basin, secondary sedimentation basins; For building waste of guaranteeing safety and avoiding the working-yard etc. drops in the pond, adopt cover plate to cover at the top, pond, and in clean water basin, utilize the submersible pump anchor that submersible pump is installed, and submersible pump is installed on the water pump anchor, can prevent effectively that mud from stopping up submersible pump.A described Accrete clearing device, secondary Accrete clearing device by the short groove of dress mud, be installed in hanger on the short groove, wear the lifting rope that hangs on the hanger and constitute.Described cover plate adopts precast concrete cover.
3) sewage with the working-yard is discharged in the primary sedimentation basin by water exhaust system, sewage water inlet, be discharged into secondary sedimentation basins through a water hole by partition wall behind the primary sedimentation, be discharged into clean water basin through after the secondary sedimentation by the secondary water hole, the clear water water outlet by clean water basin is discharged in the municipal drainage pipe or is drawn into the working-yard through submersible pump and can use at suitable water place again.
4) regularly an Accrete clearing device in primary sedimentation basin, the secondary sedimentation basins, secondary Accrete clearing device are proposed to lay into after the pond is cleared up according to the muddy situation of sewage, so circulation is carried out again.
Described short groove adopts the short groove of rectangle, is welded by steel sheet; Described hanger is two, and promptly left hanger, right hanger adopt reinforcement fabrication and the welded and installed two ends at the short groove of rectangle; Described lifting rope adopts wireline or nylon rope, and the two ends of lifting rope are hung on left hanger, the right hanger.
After settlement of sewage purifying treatment in working-yard of the present invention, recoverying and utilizing method adopt above technical scheme, have the following advantages:
(1) construction is simple, easy to operate, safe and reliable.
(2) settlement of sewage that can effectively carry out the working-yard is handled, is recycled.
(3) can effectively reduce the environmental pollution that building operation causes.
(4) effectively the conserve water resource, reduce construction cost.
