"A New Process for Advanced Treatment of Coking Wastewater" Selected by the Proceedings
A paper entitled “A New Process for Advanced Treatment of Coking Wastewater” by Li Kangjie, Shanxi Sunshine Huatai Energy Co., Ltd., Li Jianjie, Maanshan Iron and Steel Co., Ltd., and Yang Junhua, coking company of Maanshan Iron and Steel Co., Ltd., and Li Jun and Liu Lihua, was awarded the China Co The Proceedings of the 10th Symposium on Energy Saving, Environmental Protection and CDQ Technology held by the Metallurgical Coking Information Network was accepted.
This paper combines the actual application of our new process in Shanxi Sunlight Huatai Energy Co., Ltd. and adopts the EFM electromembrane integration device as a pretreatment, which changes the ratio of hydrophobic organic matter and hydrophilic organic matter in the waste water, and provides the follow-up RO membrane treatment. Reliable protection; reverse osmosis RO membrane is not only desalinated, but also can reduce the color, COD and ammonia nitrogen indicators, water production can be used as hydrated water or recirculating water make-up water; this set of system investment, small footprint, low operating costs, operation In three years, it solved the problem of the way out of Sun Huatai coking wastewater biochemical treatment.
The investment and operating costs of this set of equipment are only less than 50% of the conventional treatment technologies in the industry. This also solves the problem that coking companies have long been plagued by the inability of wastewater treatment to invest and the cost is too high to survive. The system achieves stage 1 of tons of water. The direct cost of treatment is less than 4 yuan/ton, and the total operating cost of the ton water treatment in stage 2 will not exceed 8 yuan/ton, which is the case in dealing with the highly complex and difficult high-salt organic wastewater of coking wastewater. Has a very obvious economic value.
Through nearly three years of operation, this device has proved to be the result of leading technology and reliability, the lowest investment cost, the shortest process route, and the lowest operating cost. All the indicators are ahead of their peers, providing the necessary zero-emissions for coking wastewater. Indispensable technical support has provided a qualified demonstration sample project for realizing zero-emission control of wastewater in the Chinese coking industry.
