Utility model content
The purpose of this utility model provides a kind of chemosynthesis production of raw medicine sewage pretreatment device with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: the utility model comprises water inlet pipe, mixing pit, flocculation sedimentation tank, Fenton reactor, water shoot, whipping appts and flocculation basin overflow weir, described water inlet pipe is arranged at a side of described mixing pit, between the epimere of described mixing pit and the epimere of described flocculation sedimentation tank, communicate, the lower end of described flocculation basin overflow weir is provided with intermittent type mud discharging mouth, described whipping appts is arranged in described mixing pit, described flocculation basin overflow weir is arranged at the edge of described flocculation sedimentation tank upper end and is connected with described Fenton reactor, described water shoot is arranged at the side of described Fenton reactor.
Particularly, described whipping appts is comprised of stirring rake and stirring rake motor, and described stirring rake is placed in described mixing pit, and described stirring rake motor is arranged at the upper end of described mixing pit.
Further, the pH regulator grug feeding jar that the upper end of described mixing pit is connected inside and outside being also provided with; The flocculation agent grug feeding jar that the upper end of described flocculation sedimentation tank is interlinked to the outside in being also provided with.
The beneficial effects of the utility model are:
The utility model is a kind of chemosynthesis production of raw medicine sewage pretreatment device, compared with prior art, the utility model is particularly suitable for the processing of the poor chemosynthesis production of raw medicine waste water of biodegradability, after waste water is processed by this device, can effectively improve waste water BOD/COD index, make waste water there is biodegradability, make the follow-up biochemistry of production of raw medicine waste water be treated as possibility.
