Primary wastewater treatment device

Abstract

The invention discloses a primary wastewater treatment device. The primary wastewater treatment device comprises a treatment tank, and a movable retaining plate is connected in an inner cavity of the treatment tank and partitions the inner cavity of the treatment tank into two independent chambers including a sedimentation chamber and a filter chamber from right to left. A rotary-cut stirring mechanism is connected in the sedimentation chamber, an impurity purification mechanism is movably connected in the filter chamber, and a base plate is arranged at the bottom of the treatment tank. By the primary wastewater treatment device, triple wastewater purification treatment including rotary-cut stirring, coagulating sedimentation and impurity filtration can be realized; cutters and brushes are completely used for rotary cutting of wastewater and rotary brushing and stirring of impurities, and accordingly the wastewater and flocculating agents can be mixed thoroughly to reduce harmful substances and suspended solids in the wastewater, and primary wastewater treatment quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a waste water primary treatment device. Background technique [0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, making full use of water resources. The process of separating pollutants in wastewater or converting them into harmless substances. With the enhancement of people's awareness of environmental protection, different types of wastewater primary treatment devices have appeared on the market. [0003] However, the current wastewater primary treatment devices on the market are complex in structure, cumbersome in operation, poor in treatment effect, high in impurities, and low in overall wastewater treatment quality, making subsequent wastewater treatment difficult, labor-intensive, and costly, and difficult to meet people's us...
