Is dongjiakou Chemical Industry Park polluted?

According to local news media, dongjiakou Chemical Industry Park is not polluted at present. The environmental protection measures of Qingdao dongjiakou Economic Zone Chemical Industry Park mainly rely on the self-built environmental protection treatment facilities, supporting infrastructure and urban infrastructure of the park, and the supporting sewage pipe network sends the park wastewater to the sewage treatment plant for centralized treatment. Part of the production heat in the park comes from the coal-fired boilers of Qingdao Haijing Chemical Group Co., Ltd. in the park, and part depends on the coal-fired boilers of Huaneng Qingdao Port Co., Ltd. outside the park (Qingdao Haijing Chemical Group Co., Ltd. and Huaneng Qingdao Port Co., Ltd. have carried out ultra-low emission transformation in the production and operation process). Domestic waste will be sent to the municipal domestic waste treatment plant for centralized treatment. General industrial solid waste will be treated according to the principle of "reduction, harmlessness and recycling" and will not be discharged. Hazardous waste will be entrusted to qualified units for treatment and disposal. The environmental protection facilities in the chemical industry park rely on the environmental protection facilities and urban infrastructure built by the enterprises in the park, which reduces the investment and ensures the stability of treatment. Environmental protection measures are feasible, which can ensure the stable discharge of pollutants up to standard.
