摘要/Abstract

摘要： 针对传统高盐废水处理采用“膜浓缩+蒸发结晶”方法存在的问题，研究了高盐水零排放系统预处理的软化、除硅、除浊环节，指出相较于传统预处理方法，管式微滤膜具有明显的优势。以内蒙门克庆和榆林小纪汗煤矿项目为例，通过小型试验和中型试验对该工艺系统进行了研究和分析，采用管式微滤膜(TMF)替代澄清池进行固液分离。研究应用结果表明，在进水钙离子浓度为712.5 mg/L，镁离子浓度为110.4 mg/L，总硅(以SiO2计)含量为120 mg/L的条件下，通过加入偏铝酸钠、氯化钙、氯化镁等药剂进行混凝后，利用管式微滤膜进行固液分离，SiO2去除率≥95%，出水满足钙离子浓度≤10 mg/L，镁离子浓度≤10 mg/L，总硅(以SiO2计)含量≤10 mg/L的要求，且满足反渗透进水的浊度≤1 NTU和SDI≤5的要求，运行成本相比原有工艺节省10%～20%。

Abstract: When treating the DTRO concentrated water from Yulin Xiaojihan Coal Mine, tubular microfiltration membrane (TMF) is used instead of the clarifier for solid-liquid separation. Under the condition that the calcium ion concentration of the incoming water is 210 mg/L, the magnesium ion concentration is 221 mg/L, and the total silicon content is 160 mg/L, coagulation is carried out by adding sodium metaaluminate, calcium chloride, magnesium chloride and other agents. Afterwards, the tubular microfiltration membrane is used for solid-liquid separation. The SiO2 removal rate is ≥95%. The effluent meets the requirements of calcium ion concentration ≤10 mg/L, magnesium ion concentration ≤10 mg/L, and total silicon content ≤10 mg/L. And it meets the requirements of reverse osmosis inlet water turbidity ≤ 1 NTU and SDI ≤ 5, Compared to the original process, the operating cost is saved by 10% to 20%.
