High-salinity wastewater treatment to reduce high-salinity wastewater discharge
High-salinity wastewater treatment devices mainly purify wastewater with a salt content exceeding 1%. Many industrial processes generate large volumes of wastewater that cannot be directly recycled. However, direct discharge would severely pollute the environment. Therefore, this equipment is needed to purify high-salinity wastewater, thereby reducing its discharge.
1. Reduce high-salinity wastewater discharge, avoid the discharge of highly toxic and difficult-to-degrade substances, and solve wastewater treatment problems.
2. Reducing the discharge of high-salinity wastewater allows for wastewater reuse, reduces industrial water consumption, and recovers wastewater. High-salinity wastewater treatment conserves water resources, alleviates current water shortages, and achieves zero discharge of high-salinity wastewater.
3. High-salinity wastewater treatment Can solve End-of-pipe water cannot Discharge problems. In many places, wastewater treatment ponds are excavated Treating end-of-pipe wastewater ， Not only Causes a waste of land resources, seriously Such situations threaten the groundwater environment.
How to solve partial blockage problems in high-salinity wastewater treatment?
Because high-salinity wastewater has a high salt content, blockage is prone to occur during filtration and separation:
1. Add soda ash to the pump return pipe, avoiding excessive addition.
2. Increase air agitation around the flow guide tube in the coagulation tank to prevent sludge from resettling and blocking the flow guide tube's downstream channel.
3. Add air agitation to the outlet weir of the coagulation tank; this prevents increasing sludge accumulation around the weir plate.
4. When the system is operating at low load, increase the overflow of the high-density pool to ensure a high inflow rate, preventing blockage of the high-salinity wastewater treatment pipeline due to low flow.
5. After the system stops running, the high-density pool pipes need high-pressure cleaning.
