First, the device overview
Rotary decanter is based on the digestion of foreign technology developed, designed specifically for the sequencing batch biological treatment system, with good hydraulic mechanical properties. Decanter can be realized during the weir flow into the laminar flow state, Decanter depth adjustable, adjustable resorted to water, it is a cyclic activated sludge process of key equipment. ? The decanter precise stroke is adjustable, with a decanter effective, sensitive and reliable, low power consumption, no noise, high degree of automation, easy centralized management, small size, low failure rate, easy maintenance.

Third, the principle
Rotary Decanter Decanter by the apparatus, gear, buoys skimming devices and slewing bearings and other components. Drive mechanism driven by telescopic pusher decanter device and skimmer float means rotating around a rotary bearing so that the mobile decanter weir and down, the supernatant was decanted to achieve the purpose. By a decanter weir, branch pipe, dry pipe, can be rotated 360 ° swivel support, sliding support, drive, automatic control devices and other components. When working in the driving device, decanter decanter weir to the bottom of the rotary support axial centerline testimony shift circular motion, the supernatant SBR reaction pool in this process will flow through Decanter Decanter weir branch, and then by decanting dry discharge pipe. After completion of Decanter, decanter weir slewing centerline to the bottom of the decanter axis direction for uniform circular motion, so decanter weir stopped at the standby position until the water, biochemical reactions, precipitation processes completed before decanter for the next process.
Decanter is a batch activated sludge process (Seguencing Batch Reactor Activated Sludge Process abbreviated as SBR) sewage treatment must be equipped with a mechanical device. Sewage mechanism batch activated sludge and conventional activated sludge process the same, the difference is that raw sewage flows through the individual processing units is not sequentially but let it flow to a single reactor pool, in chronological order to achieve different operating purposes, the basic procedures by the water (fill), reactive (react), precipitation (settle), water (draw) and standby (idle) composed of five basic processes. Sewage flows from the beginning to the end of a period of standby time. Decanter by the time relay inside the cabinet and lead the auger drive switching apparatus, to achieve timing quantitative water discharge standard treatment, so that the ultimate goal of achieving continuous SBR tank sewage treatment.
