一种高毒性焦化酚氰废水处理回用系统
摘要：
本实用新型属于钢铁冶金焦化酚氰废水处理的技术领域，特别是提供了一种高毒性焦化酚氰废水处理回用系统。主要包括预处理、生物脱碳脱氮、高效沉淀、芬顿高级氧化及污泥脱水五个工序，处理焦化酚氰废水和焦炉煤气水封水以及混合煤气水封水，特别是解决了目前焦化酚氰高毒性（含硫在400mg/L左右，总氮700mg/L左右）废水处理回用的问题，不需要投加稀释水运行成本低，节能减排，管理方便，并且处理效果好，去除效果稳定。
摘要（英）：

The utility model belongs to the technical field of iron and steel metallurgy coking phenol cyanogen waste water treatment, and particularly provides a highly toxic coking phenol cyanogen waste water treatment and recycling system. The highly toxic coking phenol cyanogen waste water treatment and recycling system mainly comprises five processes, namely pretreatment, biological decarbonizing and denitrification, efficient precipitation, Fenton advanced oxidation and sludge dewatering, aims to treat coking phenol cyanogen waste water, coke oven gas water seal water as well as mixed gas water seal water, and particularly solves the problem of highly toxic coking phenol cyanogen waste water (sulfur content is about 400 mg/L and total nitrogen content is about 700 mg/L) treatment and recycling. By adopting the highly toxic coking phenol cyanogen waste water treatment and recycling system, dilution water does not need to be added, so the running cost is low, energy conservation and emission reduction are realized, the management is convenient, the treatment effect is good, and the removal efficiency is stable.
