2.Features:
1. The acid pickling wastewater recycling equipment includes water conditioning tank, dosing tank, pretreatment pond, chromium reduction tank, neutralization pool, flocculation, inclined tube sedimentation tank, sludge tank, mud cake machine and water reusing tank, etc.
2. Harmful substances in the wastewater are removed through Mechanical and chemical methods of Reduction - neutralization - flocculation - sedimentation - filter press, etc to make the Quality of discharged water meet the national environmental protection standards, and can be used again. Thus it meets the water requirement repetitious washing in acid Pickling and alkaline, and reduces the emissions of wastewater at the same time.
3. Each dosing processes are equipped with on-line monitoring to control the dosage in real-time, thereby limiting the drug consumption and the Wastewater recycling cost to lowest. |
