Background
Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people.
The A/O process is widely applied to sewage treatment at present. The A/O biological treatment process consists of two parts, namely anaerobic part and aerobic part. After the sewage enters the anaerobic tank, the function of anaerobic microorganisms is utilized under the anaerobic condition, and anaerobic bacteria are mainly utilized to treat organic matters in the sewage. The sewage enters an aerobic tank after being treated by anaerobic microorganisms, and pollutants in the sewage are oxidized and decomposed by utilizing the metabolism of the aerobic microorganisms. The aerobic biological treatment is to take part in aerobic microorganisms and facultative microorganisms, and decompose organic matters into CO under the condition of dissolved oxygen2And H2O and release energy for metabolic processes. The hydrogen removed in the organic matter oxidation process is oxygen as a hydrogen acceptor, the organic matter is decomposed thoroughly, and the final product is CO with the lowest energy content2And H2O, so the released energy is more, the metabolism speed is fast, and the metabolite is stable.
Whether the anaerobic reaction tank is in the anaerobic stage or the aerobic reaction tank is in the aerobic stage, most sludge can be taken away when water flows out of the reaction tank, so that the sludge storage in the reaction tank is greatly reduced, the treatment effect cannot be achieved, partial sludge must flow back, and the number of active microorganisms in the reaction tank is ensured. The existing sludge recovery device is generally a sedimentation tank, a square cement tank is mostly adopted, a water inlet pipe is arranged at an upper end opening of the sedimentation tank, sewage is directly pumped into the sedimentation tank by a water inlet pump, and sludge is sent back to a front aerobic or anaerobic tank by a pipeline after being precipitated in the sedimentation tank. The sludge recovery system with the structure needs to pump sludge into the sedimentation tank by the water pump, has large energy consumption, easily flushes the settled sludge again in the water inlet process, has long sludge settling time and poor settling effect, and is inconvenient for collecting and refluxing the settled sludge.

The gas-liquid separator 7 comprises two clapboards 71, two ends of the clapboards 71 are connected to the inner wall of the separation box body 1, the tops of the two clapboards 71 are intersected to form a 60-degree included angle, and triangular overflow holes 13 are formed in the separation box body 1 corresponding to the intersection of the tops of the clapboards 71.
The lower part of the sewage buffer zone 3 is the water inlet surface of the sewage buffer zone 3, and the upper part is the water outlet surface of the sewage buffer zone 3. The solid-liquid separation zone 4 is provided with a plurality of mud-water separation sloping plates 8, the mud-water separation sloping plates 8 are obliquely and parallelly arranged at intervals, and the included angle between the mud-water separation sloping plates 8 and the horizontal plane is 60 degrees.

The utility model discloses the theory of operation is:
the sewage has turbulence phenomenon in the reaction tank, the sewage firstly enters the gas-liquid separation zone 2 from the water inlet 11 at the bottom of the separation box body 1 and flows upwards, and the bubbles in the water flow move to the top of the gas-liquid separator 7 along with the flow of the water flow and then are discharged from the overflow hole 13. Therefore, the sewage with high flow speed and serious turbulence phenomenon originally can slow down the sewage flow speed and alleviate the turbulence phenomenon because of the blockage of the gas-liquid separator 7 and the reduction of gas in water.
When sewage flows to the sewage buffer area 3, the flow speed of the sewage is continuously slowed down, and the sewage flows more stably. When sewage continuously flows upwards and comes to the solid-liquid separation zone 4, the mud-water separation phenomenon occurs due to the action of the mud-water separation inclined plate 8, large-particle sludge is precipitated downwards from the inclined mud-water separation inclined plate 8 along the inclined direction of the inclined plate due to the action of gravity, and water flow continuously flows upwards.
The sewage continues to flow upwards, when the sewage arrives at the clear water buffer zone 5, the flow velocity of the water flow continues to slow down to become almost static water flow, small particle impurities in the sewage also settle downwards due to the action of gravity, and at the moment, the sewage in the clear water buffer zone 5 becomes almost static clear water which is clearer.
The clear water continues to flow upwards and comes to the clear water outlet area 6, the clear water can enter the clear water overflow trough 9 from the side of the clear water overflow trough 9 without the overflow weir 91, the clear water flows out from the side with the overflow weir 91, and finally the clear water is discharged from the water outlet 12 at the top of the separation box body 1.
Sewage passes through the utility model discloses the solid three-phase separation of gas-liquid not only can be realized to mud-water separator's effect, can also reach the effect of mud-water separation and steady sewage speed, takes away too much mud when preventing that the sewage from flowing out, causes biochemical pond load capacity to reduce.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
