Baiyao treatment plan for sand washing wastewater in sand washing plant

Baiyao for sand washing wastewater of sand washing plant is an organic polymer, which can quickly separate and settle the mud waste water produced in sandfields, quarries, mines, and drilling to achieve the purpose of mud-water separation. The mud dehydrating agent. Sand washing wastewater is mainly mud water containing fine mud particles. According to the nature of the stone washing powder or sand bag soil at the sand washing site, the general appearance of this kind of wastewater is earthy yellow or reddish. The suspended fine mud particles in the wastewater are relatively fine and difficult to separate in a short time. Floor. Need to quickly clarify by adding Baiyao (polyacrylamide flocculant) for sand washing wastewater.


Baiyao for sand washing wastewater

Sand washing wastewater treatment plan:

1. Natural precipitation. Sand washing sewage contains more suspended sediments and has a larger specific gravity. Therefore, clarification can also be achieved through sufficient time of sedimentation. However, the natural precipitation method has major drawbacks. One is that it requires a large number of storage tanks, and the other is that it takes a long time to settle, which is difficult to meet the needs of production and requires a large area.

2. The method of adding flocculant of Shashabaiyao is adopted. The sand washing sewage is discharged from the sand washing machine, and then add Capitel sand washing wastewater special baiyao (polyacrylamide) for flocculation reaction. The reacted sewage flows into the first sedimentation tank (usually three sedimentation tanks), and the flocculation reaction is the first In the sedimentation tank, the mud settles quickly, so the amount of mud in the first tank is relatively large. The sewage in the third sedimentation tank is generally clear and is mainly reused as circulating water.

The mud in the sedimentation tank is pumped out by the mud pump into the sludge thickening tank, and polyacrylamide agent needs to be added again in the thickening tank. After flocculation, the mud with a higher bottom concentration is pumped out into the mud-water separation equipment through the mud pump. The mud drawn from the thickening tank needs to be flocculated by adding polyacrylamide for the third time, and then the mud and water are separated by a filter press. The effluent from the filter press enters the sedimentation tank, and the dry mud is transported out.

Shabaiyao (polyacrylamide) has a high molecular weight, and is a water treatment flocculant with faster and better treatment effects in the field of water treatment. And the dosage is small, the effect is quick, and it can meet the sand washing wastewater treatment needs of the sand washing plant. The specific type of (Baiyao) polyacrylamide used for waste water treatment in the washing field depends on the composition of the sewage water quality and the local geological conditions. It is necessary to conduct a small experiment and then a large-scale test on the machine to determine a more suitable polyacrylamide. Model and dosage.
