Eddy flow-advection detritor for initial rainwater processing
The invention relates to a rainwater processing facility, specifically to an eddy flow-advection detritor for initial rainwater processing. The eddy flow-advection detritor solves the problems of high energy consumption, strict water flow velocity and flow control and incapability of effective organic pollutant processing of a conventional detritor. The eddy flow-advection detritor comprises an eddy flow advection sand settling unit and an advection sand settling unit, a separator plate is arranged on the central section of a main water channel, and a water channel is sequentially provided with a flocculating agent adding pipe, a mechanical revolution grating, a coagulant aid adding pipe and the eddy flow sand settling unit. A flow baffle plate is arranged between the separator plate and a water outlet channel, and the water outlet channel is respectively connected with a advection sand settling unit. The water outlet channel is connected with a water outlet pipe, a mud discharging valve is arranged on the bottom of a sand storage hopper, a mud collecting pool is arranged on the opening portion of the mud discharging valve, and the bottom of the mud collecting pool is connected with an air mud-discharging pipe. The eddy flow-advection detritor is advantageous in that medicament and rainwater are stirred and mixed in an eddy flow detritor to control water flow velocity, the electric energy consumption is reduced, the occupation area of the pool body is reduced, the capability for processing organic matters, heavy metals and other pollutants and sedimentation rate are improved, the length of the detritor is reduced, and maintenance of equipment becomes easier.
