The Disscussion About The Final Outlet Of Industrial Wastewater In Coal Chemical Industry

Xingtai industrial park of Risun Coal Chemical Group is an integrated industrial base which has coke, coal tar, crude benzol hydro-refining, coke oven gas to methanol. At present, all kinds of industrial park wastewater is mainly used for coke quenching, after processed to achieve the requirement of the corresponding country.Recently, with the nationwide haze weather frequently, and the state environmental protection requirements increased sharply, the enterprise pressure of environmental protection also increased, this is not only related to the environmental protection cost of enterprise, also related to the survival of enterprise, in response to a national higher environmental requirements, enterprise have to improve the environmental protection measures. To reduce the coke quenching on the impact of the atmosphere, wet coke quenching gradually changed to dry coke quenching. And xingtai area is an extreme lack of water area, in order to save water resources, gradually restore xingtai groundwater, eventually reproduce "spring city", Risun group xingtai industrial zone cooperated with the goverment, have shuted down part of the deep well, thus the final way out for the water and waste water face a bigger challenge, which requires the waste water must be advanced treatment so as to improve the utilization of waste water, must be to secondary recycling of waste water as much as possible, even achieve zero emissions. Only the effluent is better and better, In this way can make the enterprise do to save water, green production.In this paper, through the research of industrial park wastewater, combined with the national environmental policy, the final way of processing the Industrial park wastewater is discussed in this paper. Through expert discussion, investigation, working out a set of suitable method for wastewater treatment, eventually make the ef-fluent as to meet the requirement of industry recycling reclaimed water.
