Abstract

The invention relates to an activated sludge reaction system which comprises a reactor and a replacement device connected with the reactor, wherein the replacement device comprises a replacement tank which is basically parallel to the high pressure area of the reactor, and a water inlet valve and a water outlet valve which are communicated with the replacement tank; the replacement device also comprises an exhaust valve arranged on the top of the replacement tank; a first circulating pipeline and a second circulating pipeline are also arranged; the replacement tank is communicated with the reactor respectively by virtue of the first circulating pipeline and the second circulating pipeline; the first circulating pipeline is provided with a first circulating water valve, and the second circulating pipeline is provided with a second circulating water valve; and the first circulating pipeline or the second circulating pipeline is provided with a flow push device. The activated sludge reaction system can be used for replacing the inflow water and outflow water of the rector by the replacement device, so that the total energy consumption is lower than the water inlet energy consumption of a reactor barrel.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an activated sludge reaction system. Background technique [0002] Activated sludge method is an aerobic biological treatment method that uses microbial flocs to treat wastewater. The principle of activated sludge method is to use aerobic microorganisms in water to absorb and consume organic matter under aerobic conditions, thereby removing organic pollutants. . The activated sludge treatment system is basically composed of an aeration tank, an aeration device, a sedimentation tank and sludge return equipment. Under the aeration of the device, the sewage is in full contact with the activated sludge, and the organic matter in the wastewater is adsorbed by the activated sludge, and is metabolized and decomposed by the microbial population in the activated sludge, thereby reducing the content of organic matter in the water. [0003] The aeration tank in the activated sludge met...
