Description

Orchid mela precipitation device Technical Field The utility model relates to the technical field of sewage treatment, in particular to a orchid-Meira precipitation device. Background The orchid sedimentation tank is applied to industries such as electroplating wastewater, papermaking wastewater, industrial production wastewater, pretreatment of filtration, filtration effluent and back flushing water, river water purification, sludge concentration and the like, can effectively separate solids in liquid, can create a good laminar flow environment, and achieves a better sedimentation effect. When the traditional precipitation equipment is used for treating sewage containing oil and suspended matters, the problems of low sedimentation efficiency, insufficient oil-water separation, easiness in secondary floating of sludge and the like are commonly existed. While the conventional inclined plate sedimentation tank improves the efficiency by increasing the sedimentation area, uneven water flow distribution easily causes the disturbance of a sludge accumulation area caused by water inlet impact to influence the sedimentation effect, and meanwhile, the lack of an oil stain separation structure causes the discharge of floating oil along with clear water to influence the quality of effluent water. Disclosure of utility model 1. Technical problem to be solved The utility model aims to provide a Lanmela precipitation device which can effectively improve oil-water separation, increase suspension retention time, effectively inhibit secondary floating of suspended sludge particles and improve sedimentation effect. 2. Technical proposal The utility model is realized by the following technical scheme: The utility model provides a orchid-Mela precipitation device which comprises a shell, wherein a mud discharging area, a sedimentation area, a water inlet area and a clear water area are arranged in the shell, the sedimentation area is arranged above the mud discharging area, a plurality of inclined plates are arranged in the sedimentation area in parallel, a water inlet joint communicated with the water inlet area and a water outlet joint communicated with the clear water area are arranged on the side face of the shell, a mud discharging opening communicated with the mud discharging area is arranged at the bottom of the shell, the water inlet area is communicated with the sedimentation area below the water inlet area, the sedimentation area and the clear water area are separated by a first baffle plate fixed in the shell, a diversion groove is formed in the surface of the first baffle plate, an oil filtering box is fixed on the side face of the shell, an oil filtering groove communicated with the oil filtering box is horizontally formed in the surface of the shell, and the height of the diversion groove is lower than that of the oil filtering groove.
