The invention discloses a combined type novel water decanter-free SBR membrane separation device sewage treatment system which comprises a raw water pool, an SBR reaction pool, a membrane separation pool, a control device, a first aeration device and a second aeration device; a lift pump is arranged between the raw water pool and the SBR reaction pool, a water inlet of the lift pump is communicated with the bottom of the raw water pool, and a water outlet of the lift pump is communicated with the upper part of the SBR reaction pool; the upper part of the SBR reaction pool is communicated with the upper part of the membrane separation pool through a water pipe; a central water distributor is arranged in the SBR reaction pool, the central water distributor is communicated with the water outlet of the lift pump and a water outlet of the central water distributor is positioned at the bottom of the SBR reaction pool; the first aeration device is communicated with the bottom of the SBR reaction pool, and the second aeration device is communicated with the bottom of the membrane separation pool; and the control device is used for controlling the lift pump, the first aeration device and the second aeration device. According to the disclosed scheme, the combined type novel water decanter-free SBR membrane separation device sewage treatment system has the characteristics of being short in technology flow, high in sewage treatment efficiency, good in effect, and stable in the quality of outflowing water.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a new composite sewage treatment system without a decanter SBR plus a membrane separation device. Background technique [0002] SBR is the abbreviation of Sequenced Batch Activated Sludge Process, which is an activated sludge sewage treatment technology operated by intermittent aeration. Its main feature is the orderly and intermittent operation in operation. The core of SBR technology is the SBR reaction tank, which integrates functions such as homogenization, primary sedimentation, biodegradation, and secondary sedimentation into one tank. There is no sludge return system. It is especially suitable for occasions with intermittent discharge and large flow changes. [0003] However, as my country's water environment pollution and water resource shortages become increasingly severe, the national and local environmental protection departments have increasingly raised the ...
