The wastewater enters the reaction chamber 10a from the water inlet 11, the wastewater flows out from the water outlet 12 after being subjected to anaerobic treatment in the reaction chamber 10a, gas generated in the anaerobic reaction process is discharged out of the reaction chamber 10a through the gas outlet 13, the wastewater enters the degasser 20 through the water treatment inlet 21 for degassing treatment, then flows out from the water treatment outlet 22, enters the solid-liquid separation device 30 through the sedimentation water inlet 31 for solid-liquid separation, sludge in the wastewater is discharged from the solid outlet 33 after being subjected to sedimentation separation and flows back into the reaction chamber 10a, and supernatant in the solid-liquid separation device 30 flows out from the water outlet 12, so that the wastewater treatment is completed.

In the purification system of the related art, as the anaerobic reaction proceeds, the sludge generates gas, the gas is likely to generate turbulence in the wastewater due to the floating of bubbles after entering the solid-liquid separation device along with the wastewater, the solid in the wastewater floats in a turbulent state, so that the solid is less likely to be precipitated and separated, and if a large amount of solid remains in the wastewater in the reactor, the gas discharge is affected. In the purification system 100 of the embodiment of the present invention, the wastewater is degassed by the degasser 20 before entering the solid-liquid separation device 30, and the gas in the wastewater is removed, so that the flocculent precipitate in the wastewater is easily separated in the solid-liquid separation device 30.

That is, the installation height of the deaerator 20 is higher than the installation height of the solid-liquid separation device 30, the wastewater flows to the solid-liquid separation device 30 from top to bottom after being deaerated in the deaerator 20, and the pressure applied to the wastewater is gradually increased in the process, so that the gas remained in the wastewater is dissolved in the wastewater, and thus, the effect of the deaerator 20 on separating the gas in the wastewater can be improved, and the disturbance of the gas on the wastewater in the solid-liquid separation device 30 is further reduced.

According to the utility model discloses purification system 100, through set up degasser 20 between reactor 10 and solid-liquid separation equipment 30, the waste water in the reaction chamber 10a is discharged by delivery port 12 through anaerobic treatment after, degasser 20 can get rid of the gas in the waste water to make the solid in the waste water not receive the disturbance of gas, improve the effect that the solid subsided or stratified, thereby make the solid separate out from waste water, solid-liquid separation's effect is better. Secondly, degasser 20 is disposed outside reactor 10, and degasser 20 is installed at a flexible position, thereby facilitating the disassembly, assembly and maintenance of degasser 20. Therefore, according to the utility model discloses purification system 100 can separate the gas in the waste water, and is better to the separation effect of the solid in the anaerobism play water to gas has been avoided being detained in reactor 10. Further, by setting the position of the deaerator 20 in the vertical direction to be higher than the position of the solid-liquid separation device 30, the separation efficiency of the deaerator 20 with respect to the gas can be improved, and the influence of the gas remaining in the wastewater on the solid-liquid separation effect of the solid-liquid separation device 30 can be avoided, thereby further improving the solid-liquid separation effect of the purification system 100.

Specifically, the degasser 20 separates the gas in the wastewater, the separated gas forms gas with the upper wastewater in the degasser 20, the gas flows out of the degasser 20 through the gas outlet 23 and flows back to the reactor 10 through the gas inlet 14, and finally exits the reactor 10 through the gas outlet 13, thereby reducing the waste of gas (such as biogas) generated during the anaerobic reaction process and achieving high gas recovery rate.

A purification system 100 according to some embodiments of the present invention is described below with reference to fig. 1.

As shown in fig. 1, the water inlet 11 is disposed on a side wall of the reactor 10 and adjacent to a bottom wall of the reactor 10, and the water outlet 12 is disposed on a side wall of the reactor 10 and adjacent to a top wall of the reactor 10. Specifically, the flow direction of the wastewater in the reaction chamber 10a is from bottom to top, and since the water outlet 12 is disposed adjacent to the top wall of the reactor 10, that is, the position of the water outlet 12 is higher than the position of the solid-liquid separation device 30, the degasser 20 is configured to remove the gas dissolved in the wastewater, thereby reducing the disturbance effect of the bubbles on the wastewater in the solid-liquid separation device 30, and further improving the solid separation effect of the solid-liquid separation device 30 on the wastewater.

As shown in fig. 2, the water inlet 11 is disposed on the top wall of the reactor 10, and the water outlet 12 is disposed on the side wall of the reactor 10 and adjacent to the bottom wall of the reactor 10. Specifically, the flowing direction of the wastewater in the reaction chamber 10a is from top to bottom, because the water outlet 12 is arranged near the bottom wall of the reactor 10 and the position of the water outlet 12 is lower than the position of the deaerator, the pressure of the wastewater is gradually reduced in the process of flowing from bottom to top from the water outlet 12 to the deaerator, so that the gas dissolved in the wastewater is released, the deaerator separates the gas released in the wastewater and discharges the gas from the gas outlet 23, and the separated gas flows back into the reactor 10 through the gas inlet 14, so that the gas remained in the wastewater can be further separated, and the solid-liquid separation effect of the solid-liquid separation device 30 is improved.

Because the direction that waste water flows in reaction chamber 10a is from top to bottom, through locating circulation export 15 below circulation import 16 and the diapire setting that is close to reactor 10, can make waste water form a complete backward flow water route to make waste water carry out circulation treatment in reactor 10, anaerobic treatment's effect further promotes.

Further, a reflux pump 50 is disposed between the circulation inlet 16 and the circulation outlet 15, and the reflux pump 50 is used for refluxing the sewage at the bottom of the reaction chamber 10a to the top of the reaction chamber 10 a. In this way, the wastewater forms a flowing closed loop in the reactor 10 and plays a role of stirring the wastewater, thereby improving the efficiency of the anaerobic reaction, and the wastewater is in the process of circulating flow, which is beneficial to the release of gas from the wastewater, thereby avoiding the retention of gas in the wastewater.

In some alternative examples of the present invention, the solids outlet 33 communicates with the return conduit 40. Thus, after being separated by the solid-liquid separation device 30, the sludge in the wastewater can flow back to the reaction chamber 10a through the solid outlet 33 and the return pipe 40, so that the sludge can be recycled, the utilization rate of the sludge is improved, the waste of the sludge is avoided, and the operation cost is reduced.

Optionally, a sludge pump 51 for pumping sludge in the solid-liquid separation device 30 to the return pipe 40 is provided between the solid outlet 33 and the return pipe 40. This is advantageous in that the sludge separated in the solid-liquid separator 30 is returned to the reaction chamber 10a, and the sludge is prevented from staying in the solid-liquid separator 30.

Further, the reactor 10 further includes a sludge scraper 70 at the bottom of the reaction chamber 10 a. Specifically, the sludge in the reaction chamber 10a is deposited at the bottom of the reaction chamber 10a due to gravity, and by providing the sludge scraper 70 at the bottom of the reaction chamber 10a, the sludge can be prevented from accumulating at the bottom of the reaction chamber 10a and affecting the discharge of the sludge from the circulation outlet 15, thereby facilitating the discharge of the sludge from the reaction chamber 10 a.
