Background

The sedimentation tank is characterized in that PAC and PAM + are added into the wastewater, so that fine colloidal suspended particles or milky pollutants which are difficult to remove by a natural sedimentation method in the wastewater lose stability, and then are easy to naturally sink and removed due to mutual collision, aggregation or polymerization and lap joint to form larger particles or floccules, the clear water after sedimentation enters an ion exchange system, and the sludge enters a sludge system for sludge pressing.

However, the sedimentation tank in the applicant working area is a flat layer, so that sludge is not easy to discharge, and the sludge is discharged through a submerged sewage pump at the bottom of the tank; and in addition, a steel wire hose is used as a water inlet pipe for ion exchange, a water inlet pipe for ion exchange is placed below the liquid level, clear water which is settled in the settling pond is discharged, and the water discharge is stopped when the liquid level of the clear water is about 30 cm higher than the liquid level of the sludge layer. However, sometimes during night operation, because the underwater light is not strong, sometimes the underwater light is pumped to a mixed area of a sludge layer and a clear water layer, and impurities such as sludge in water enter ion exchange to cause blockage.

Most of the sedimentation basins of the sewage treatment plants adopt a decanter for draining water. The decanter is arranged at the upper part of the sedimentation tank, when the sedimentation tank is settled to be qualified, the decanter is put into the sedimentation tank, and when the liquid level is higher than the decanter, the clear water at the upper part of the tank automatically flows into the decanter for draining. However, the decanter is arranged at the upper part of the sedimentation tank, and because of the installation position, the decanter can only be put down to the middle part of the sedimentation tank and can not be put down to the bottom of the sedimentation tank, so that the clear water in the sedimentation tank can only be discharged by about 50 percent, and the clear water in the sedimentation tank can not be effectively discharged completely.

Furthermore, the open end edge of collecting the box is provided with the overflow portion of wolf tooth groove, can make things convenient for clear water to enter into in the collecting box in the sedimentation tank through this setting.

Furthermore, the vertical track extends into the sewage settling tank, and a pulley matched with the track is installed on the collecting box. Through the setting of track and pulley, can conveniently collect the steady of box and reciprocate.

Furthermore, the end part of the drain pipe is provided with a connecting flange which is convenient for installing a drain hose, and the drain hose can be used as an ion exchange water inlet pipe through the arrangement of the connecting flange which is convenient for connecting the drain hose.

Furthermore, the lifter is an electric hoist and is connected with the collecting box through a pull rope; the electric hoist is adopted as the lifter, so that the control is convenient, and the cost is low.

Furthermore, the collecting box is provided with a lifting lug, and the lifting lug is arranged to be conveniently connected with a pull rope of the electric hoist, so that the collecting box can be lifted up and down conveniently.

The utility model has the advantages of as follows:

the utility model has reasonable design, simple structure and convenient use, is arranged in a sedimentation tank (flat bed type) for sewage treatment, realizes the collection of clear water in the sedimentation tank and assists the discharge of clear water;

the sedimentation tank based on the applicant working area is a flat layer, so that sludge is not easy to discharge, and the background of sludge discharge is carried out through a submerged sewage pump at the bottom of the tank; the utility model discloses a clear water collection device has ensured that impurity such as mud does not get into the clear water and has collected the box in, arouses the ion exchange to block up, will mostly clear water discharge again, has improved sewage treatment ability greatly. In addition, the clear water collector is light and handy, convenient to use and beneficial to operation.
