Abstract

The invention discloses an energy-saving sewage treatment system based on an SBR process.The energy-saving sewage treatment system includes a water pump, a fan, a raw water tank for containing sewage and an SBR reaction tank for sewage treatment, wherein a pH determinator, a DO determinator, an ORP determinator and a mixing device are arranged in the SBR reaction tank, a water inlet pipe is connected between the raw water tank and the SBR reaction tank, the sewage in the raw water tank enters the SBR reaction tank through a water pump and the water inlet pipe, the fan is connected with an aeration pipe, the gas outlet end of the aeration pipe is connected in the SBR reaction tank, the SBR reaction tank is provided with a water outlet pipe and a blow-off pipe, and a magnetic valve is arranged on the water outlet pipe.The energy-saving sewage treatment system is stable in operating effect, simple and flexible in operation and capable of effectively reducing sewage treatment energy consumption according to the water quality of sewage and real-time treatment situation on the premise that a sewage treatment effect is ensured.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an energy-saving sewage treatment system based on an SBR process. Background technique [0002] Sewage treatment is for sustainable development, but high resource occupation and high energy consumption processes do not conform to the basic principles of sustainable development. At present, the energy consumption of sewage treatment in my country exceeds 1% of the total energy consumption of the country, which is a large energy consuming household and urgently needs to reduce energy consumption. From the perspective of emission reduction, sewage treatment will also produce carbon dioxide, and the power consumption is also converted into carbon dioxide. So energy saving is emission reduction. At present, most of the urban sewage treatment plants in my country are secondary treatment plants using the activated sludge method. The energy consumption mainly comes from aeration re...
