Key Environmental Protection Project of the Year To implement the philosophy of “ Ecology internal treatment (pre-treatment+ First, Strive for Green Development ” , hydrolytic acidification+UASB/IC+CASS+ Bayannur City, where Inner Mongolia c a t a l y t i c o x i d a t i o n + s e c o n d a r y Company is located at, has made every sedimentation tank), and was then effort to foster the integrative management discharged into Ulansuhai Nur after of Ulansuhai Nur according to the meeting the discharge standard through comprehensive management ideas of the further treatment. Inner Mongolia “ Ecological Water Replenishment, Pollution Company, however, as a major drainage Control and Reduction at Source, company in Linhe District, has actively Restoration and Treatment, Resource carried out reclaimed water reuse work Utilization, and Sustainable Development ” . since the second half of 2017 to utilise In the past, the wastewater generated by water resources, reduce fresh water intake Inner Mongolia Company was discharged and achieve the goal of zero wastewater into the industrial park centralised sewage discharge, controlling and reducing treatment plant for further treatment after pollution at source. Background Inner Mongolia Company has completed fourth and fifth sewage treatment station. three phases of the reclaimed water reuse The project was tested in the December project with handling capacity up to 37,000 2019, and the company's wastewater was tonnes/day. The first phase is a 10,000 fully recycled from the third quarter of the tonnes/day project with raw water coming Year with maximum daily treatment 3 from the acidic wastewater of the MVR capacity of 37,000 m . After treatment of evaporator condensate project; the second the reclaimed water reuse project, the phase is a 10,000 tonnes/day project with wastewater meets the standards of The raw water coming from the treated Reuse of Urban Recycling Water-Water wastewater from the company's first, Quality Standard for Industrial Uses second and third sewage treatment station; (GB/T19923-2005), and will be used to the third phase is a 17,000 tonnes/day replenish the circulating water in the project with raw water coming from the company's cooling tower and in some treated wastewater from the company's production processes. Project Status Objectives and Effectiveness In October of the Year, Inner Mongolia significant savings in water, with the Company completed the environmental Company's industrial wastewater treatment protection inspection and acceptance upon capacity being 12.25 million tonnes. The the completion of the reclaimed water project has achieved a saving of 8.13 reuse project, and officially put the project million tonnes of purchased fresh water into operation. During the Year, the and a 60% reduction in fresh new water reclaimed water reuse project achieved consumption compared to that of last year.
