新型净水剂在焦化废水深度处理中的实际应用
Practical Application of New Water Purifying Agent in Advanced Treatment of Coking Wastewater
摘要: 焦化废水是一种典型的高浓度、难降解的工业废水，其组成分复杂、毒性大、处理难度大。按国内现有处理工艺，生化处理后废水很难达到一级排放标准，然而实施新的炼焦行业污染物排放标准，使焦化废水的达标排放或回用成为迫切需要解决的难题。本文研究出新型焦化酚氰废水净水剂，在焦化废水常规工艺的深度处理过程中强化混凝的技术实际应用，不仅能够保证出水水质达到《炼焦化学工业污染物排放标准》的排放要求，解决废水外排造成的环境污染问题，提高水的重复利用率，而且节省固定投资，降低运行成本，管理操作简易，具有良好的示范意义和推广价值。
Abstract: Coking wastewater is a typical high-concentration, difficult-to-degrade industrial wastewater with complex composition, high toxicity, and difficult treatment. According to the existing domestic treatment technology, it is difficult for the wastewater after biochemical treatment to meet the first-level discharge standard. The implementation of the new coking industry pollutant discharge standard makes the discharge or reuse of coking wastewater become an urgent problem to be solved. The practical application of a new type of coking phenol-cyanide wastewater purifierin the advanced treatment process of conventional coking wastewater is introduced. It can not only ensure that the effluent water quality meets the discharge requirements of the “Coking Chemical Industry Pollutant Discharge Standard”, solve the environmental pollution problem caused by the discharge of waste water, and improve the reuse rate of water, but also save fixed investment, reduce operating costs, and easy management and operation, which has demonstration significance and promotion value.
