Embodiment Construction

[0017] Such as figure 1 Shown, the three-stage sedimentation tank, the sedimentation tank is made of concrete. The sedimentation tank is divided into a first processing tank unit 3 , a second processing tank unit 4 and a third processing tank unit 5 through the first filter screen 1 and the second filter screen 2 in sequence. The first treatment tank unit 3 is connected to the sewage pipe 6 , the bottom of the second treatment tank unit 4 is provided with a first step 7 , and the bottom of the third treatment tank unit 5 is provided with a second step 8 . A cover plate 11 made of concrete is provided above the first treatment tank unit 3 , the second treatment tank unit 4 and the third treatment tank unit 5 . The depths of the first processing pool unit 3 , the second processing pool unit 4 , and the third processing pool unit 5 decrease sequentially. The bottom of the first filter 1 is close to the top of the first step 7 , and the bottom of the second filter 2 is close to ...

Abstract

The invention relates to a three-stage sedimentation tank, which is separated into a first treatment pool unit, a second treatment pool unit and a third treatment pool unit sequentially through a first filtration screen and a second filtration screen, wherein the first treatment pool unit is connected to a sewage discharge pipe, the bottom portion of the second treatment pool unit is provided with a first step, and the bottom portion of the third treatment pool unit is provided with a second step. According to the present invention, the high viscosity wastewater generated from glass edging is subjected to the three-stage sedimentation treatment, and the treated wastewater completely meets the standard of the water for edging.

Description

technical field [0001] The invention relates to a three-stage sedimentation tank, which is used for the treatment of glass edging waste water. Background technique [0002] In the glass processing process, glass edging is the place with the largest water consumption in the entire workshop, accounting for more than 80% of the water consumption in the entire workshop. Glass edging is inseparable from water, but the viscosity of the water after grinding the glass is very high. If it is used directly, the glass will not be cleaned cleanly, which will affect the quality; but if it is discharged as sewage, it will pollute the environment and cause waste of water resources. The water after edge grinding contains a large concentration of glass powder, and it is generally necessary to drain the water once after get off work in the same day, so as not to affect the quality of glass edge grinding and cleaning effect. It takes about 5-6 tons of water to discharge each time, and the wa...
