Description
Technical Field
The utility model relates to a sewage treatment's technical field especially relates to a high density sedimentation tank dross and long-pending mud clearing device.
Background
The main technology of the high-density sedimentation tank is a carrier flocculation technology, which is a rapid sedimentation technology, the design of the high-density sedimentation tank is very compact, the high-density sedimentation tank integrates a coagulation tank, a flocculation tank, an inclined plate sedimentation tank and sludge concentration, wherein the inclined plate sedimentation tank comprises a pre-sedimentation area and an inclined plate sedimentation area. The process flow is as follows:
1. adding coagulant into the coagulation tank, quickly mixing the coagulant with suspended matters in the sewage under the action of a quick stirrer, and neutralizing negative charges on the surfaces of particles to destabilize the particles to form small flocs which then enter the flocculation tank.
2. And a flocculating agent is added into the flocculation tank, the flocculating agent promotes small flocs to form larger flocs through adsorption, electrical neutralization and mutual bridging, and the action of the slow stirrer enables the medicament and the flocs to be fully mixed without damaging the formed large flocs.
3. The flocculated sewage enters a pre-settling zone of an inclined plate settling tank for preliminary settling, then enters the inclined plate settling zone for secondary settling, particles and flocs settle on the surface of an inclined plate and slide down under the action of gravity, micro sand slides down along the surface of the inclined plate along with sludge and settles at the bottom of the inclined plate settling tank, then a mud scraper at the bottom of the settling tank scrapes the micro sand and the sludge to the middle position of the bottom of the inclined plate settling tank, a circulating pump conveys the micro sand and the sludge to a hydraulic separator, the micro sand and the sludge are separated under the action of centrifugal force, the micro sand flows out from a lower layer and directly returns to a feeding tank, the sludge overflows from an upper layer and then flows to a sludge treatment system through gravity flow, and the settled water is collected and discharged by a stainless steel water collecting tank distributed at the top of the inclined plate settling tank. Compared with the traditional flocculation process, the technology has the advantages of small occupied area, low engineering cost, impact load resistance and the like.
