Embodiment 1
[0041] A. Recycling sewage and producing reclaimed water: collecting and extracting sewer sewage from the metallurgical industry through flocculation and sedimentation to meet the reclaimed water requirement that the effluent suspended matter is less than 100mg / l.
[0042] B. Treatment of reclaimed water to reduce the content of COD and high-valent ions: introduce the above reclaimed water into the clarification tank, according to the water quality, the COD of metallurgical wastewater is 108mg / l, put in lime milk at 100mg / l, and put in powdered activated carbon, lime milk and 20mg / l Powdered activated carbon adopts a complete set of dosing devices including dry speculation, dissolution tank, metering pump and matching pipes and valves. Through the mixing, reaction, flocculation, precipitation, clarification, separation, adsorption, and filtration of clarifiers, valveless filters, and multi-media filters, some suspended solids, colloidal substances, organic substances, oils, alk...
