The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1-7, the treatment system before microbial decomposition of industrial wastewater comprises a multi-stage sedimentation tower and a water curtain type air floatation device, wherein the multi-stage sedimentation tower comprises a tower body 11, a water inlet pipe 12, a water outlet pipe 13 and a plurality of sedimentation units longitudinally distributed in the tower body 11, the sedimentation units comprise a sedimentation barrel 14 with an opening at the upper end and a water collecting cone 15 positioned below the sedimentation barrel 14, the large diameter end of the water collecting cone 15 faces upwards, the diameter of the large diameter end of the water collecting cone 15 is larger than the outer diameter of the sedimentation barrel 14, the diameter of the small diameter end of the water collecting cone 15 is smaller than the inner diameter of the sedimentation barrel 14, the water outlet end of the water inlet pipe 12 is positioned in the sedimentation barrel 14 of the uppermost sedimentation unit, a mud discharging pipe 16 is arranged at the bottom of the sedimentation barrel 14, the inner wall of the water collecting cone 15 is fixedly connected with the inner wall of the tower body 11 through a hollow mounting plate 17, a gas collecting pipe 18 is arranged at the top of the tower body 11, and the water collecting cone 15 of the lowermost sedimentation unit is connected with the water outlet pipe 13;

the water curtain type air floatation device comprises a plurality of air explosion tanks 31 which are longitudinally arranged at intervals, two sides of each air explosion tank 31 are provided with air foam collecting tanks 32, and the bottom of each air explosion tank 31 is provided with a water pipe 33;

valves are arranged on the sewer pipe 33 and the mud discharging pipe 16;

the treatment system also comprises a water pump which sends the water discharged by the water outlet pipe 13 into the aeration tank 31 at the top of the water curtain type air floatation device.

After the industrial wastewater is intercepted and filtered by the primary grating, the industrial wastewater is sent into a precipitation barrel 14 of the topmost precipitation unit, is precipitated by each precipitation unit from top to bottom, and is discharged from a water outlet pipe 13. In the sedimentation process, the water supply speed is required to be gentle, the wastewater above the overflow sedimentation barrel 14 flows into the water collection cone 15 below the overflow sedimentation barrel 14 along the upper edge of the sedimentation barrel 14, enters the next sedimentation barrel 14 under the guiding action of the water collection cone 15, and the like, the wastewater collected by the last water collection cone 15 is recovered, the substances such as sludge deposited at the bottom of the sedimentation barrel 14 are discharged out of the tower body 11 through the sludge discharge pipes 16, and each sludge discharge pipe 16 is connected in parallel to a main pipe, so that the sludge is recovered by the main pipe.

The tower type precipitation can collect waste gas containing alcohol, avoid waste gas pollution, greatly increase the volatilization area, improve the volatilization efficiency of alcohol volatile substances, reduce the alcohol content in the waste water, and also greatly reduce the occupation area of the waste water precipitation equipment.

The wastewater from the water collecting cone 15 at the bottom is sent into the gas explosion pool 31 at the top after coagulant and other auxiliary agents are added, the natural water curtain is adopted for air floatation and deslagging, air is dissolved in the process of dropping and impacting the wastewater, and then the air floatation effect is formed on the wastewater by dissipation.
