焦化废水深度处理方法及系统
摘要：
本发明公开一种焦化废水深度处理方法及系统，主要针对现有焦化废水处理工艺达不到排放要求而提出。本发明焦化废水深度处理方法及系统经过生化系统处理后的焦化废水首先经过微波辐射处理，再进行铁碳微电解催化还原处理，进一步对废水进行非均相Fenton催化氧化处理而后进行混凝沉淀处理、微滤处理，最终达到排放要求。本发明焦化废水深度处理方法及系统解决了常见的焦化废水处理工艺方法难以将经生化处理后的焦化废水处理达标的问题，具有药剂用量少、污泥产量小、能耗低、处理效果稳定高效的特点。
摘要（英）：

The invention discloses a coking wastewater advanced treatment method and system and mainly aims to solve the problem that wastewater treated with a conventional coking wastewater treatment technology cannot meet an emission standard. According to the coking wastewater advanced treatment method and system, coking wastewater treated by a biochemical system is firstly treated through microwave radiation and then is subjected to iron-carbon micro-electrolysis catalytic reduction treatment, the wastewater is further subjected to heterogeneous Fenton catalytic oxidation treatment and subjected to coagulating sedimentation treatment and microfiltration treatment, and finally, the wastewater meets the emission standard. The coking wastewater advanced treatment method and system solve the problem that the coking wastewater after biochemical treatment cannot meet the emission standard with the conventional coking wastewater treatment technology, and have the characteristics of low chemical dosage, low sludge yield, low energy consumption and stable and efficient treatment effect.
