Problems solved by technology

[0002] In the prior art, most of the sewage has a high sand content, and it is difficult to supply the subsequent sewage treatment process normally. Generally, a cyclone desander is used for sand removal treatment, and the cyclone desander can separate water from sand and gravel , but the effect of using the cyclone desander to remove sand at one time is not ideal under actual operating conditions. In addition, the separated sand will generally accumulate in the blowdown valve at the lower end of the desander, and the operator will open it regularly or according to the actual situation. The sewage valve discharges sand, but the discharged sand still contains a large amount of water. In the prior art, this part of the water is not treated, but directly discharged, causing secondary pollution. water for recycling
