A device for separating large particles of impurities in construction wastewater

Abstract

The invention discloses a large particle impurity separation device in construction wastewater, comprising: a plurality of horizontal pipes, a first U-shaped pipe, a second U-shaped pipe and a plurality of water pipe racks; the opening of the U-shaped structure of the first U-shaped pipe is upward , the opening of the U-shaped structure of the second U-shaped pipe is downward, one end of the first U-shaped pipe is connected with the water inlet pipe of the waste water pipeline through a horizontal pipe, and the other end of the first U-shaped pipe is connected with the second U-shaped pipe through a horizontal pipe. One end is connected, the other end of the first U-shaped pipe is connected to the outlet pipe of the waste water pipe through a horizontal pipe, and the water pipe rack is arranged under the horizontal pipe; the bottom of the first U-shaped pipe is provided with a first notch and is detachably mounted on The first notch cover on the first notch, the top of the second U-shaped pipe is provided with the second notch and the second notch cover detachably installed on the second notch, the second notch cover is provided with a filter screen . The arrangement of the first U-shaped pipe, the second U-shaped pipe and the filter screen of the present invention makes it more convenient to clean up large particles of impurities.

Description

technical field [0001] The invention relates to the technical field of building piping systems, in particular to a device for separating large particles of impurities in building wastewater. Background technique [0002] Due to the large water consumption on the construction site, it is necessary to lay waste water pipes to discharge the waste water, but the sewage in the pipes used on the construction site contains a large amount of floating matter and sediments such as sediment, among which the floating matter floats on the water surface and drifts with the sewage , sediment and other sediments move along the bottom of the pipe or deposit on the pipe wall, all of which will block the pipe, and in severe cases, the pipe will burst. [0003] In addition, the wastewater on the construction site contains some harmful substances, which cannot be directly discharged into the environment. It needs to be discharged into the wastewater recovery pipeline first, and finally enter the...

[0002] Due to the large water consumption on the construction site, it is necessary to lay waste water pipes to discharge the waste water, but the sewage in the pipes used on the construction site contains a large amount of floating matter and sediments such as sediment, among which the floating matter floats on the water surface and drifts with the sewage , sand and other sediments move along the bottom of the pipe or deposit on the pipe wall, which will block the pipe, and in severe cases, the pipe will burst

[0003] In addition, the wastewater on the construction site contains some harmful substances, which cannot be directly discharged into the environment. It needs to be discharged into the wastewater recovery pipeline first, and finally enter the wastewater treatment plant for treatment before discharge. When there are a lot of floating objects and mud in the pipeline When sand and other sediments enter the wastewater treatment plant, it will increase the workload of sewage treatment. Large particles of impurities will enter the sewage treatment process and cause wear and tear on the sewage treatment equipment, and even damage them in severe cases.
