Wastewater treatment device for building construction

Abstract

The invention discloses a wastewater treatment device for building construction, which comprises a silt treatment mechanism, a water flow channel, a water pump, a flocculation stirring mechanism, a pollution discharge purification mechanism, a communication pipeline and a valve II, and is characterized in that the water flow channel is arranged on one side of the silt treatment mechanism; the water pump is arranged on one side of the water flow channel, the flocculation stirring mechanism is arranged on the other side of the water flow channel, the pollution discharge purification mechanism is arranged on one side of the flocculation stirring mechanism, the communicating pipeline is arranged between the flocculation stirring mechanism and the pollution discharge purification mechanism, and the valve II is arranged on one side of the communicating pipeline; according to the invention, gravel is fully blocked and filtered, blockage in the filtering process is prevented, insufficient stirring caused by vortex is prevented in the stirring process, and the stability and safety of equipment can be ensured.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, in particular to a waste water treatment device used for building construction. Background technique [0002] The current construction waste water treatment device has the following deficiencies: 1) The sand and gravel in the waste water are separated from the water body through the filter in the first port. During the process of preventing sand and gravel from entering the mixing chamber, there will still be sand and gravel entering the mixing chamber During the mixing process, the equipment will be damaged, and the sand and gravel will also cause the blockage of the filter screen, which will make the wastewater treatment efficiency relatively low; 2) During the process of stirring and flocculation, the water flow will form a vortex in the same direction. The high flocculant will be in a relatively static state with the impurities in the water, which will reduce the efficiency of f...

During the process of preventing sand and gravel from entering the mixing chamber, there will still be sand and gravel entering the mixing chamber During the mixing process, the equipment will be damaged, and the sand and gravel will also cause the blockage of the filter screen, which will make the wastewater treatment efficiency relatively low; 2) During the process of stirring and flocculation, the water flow will form a vortex in the same direction. The high flocculant will be in a relatively static state with the impurities in the water, which will reduce the efficiency of flocculation. At the same time, with the continuous change of the eddy current speed, it will cause the shaking of the equipment, which is not conducive to safe production
