In response to the recent epidemic of new coronavirus in Beijing, the Beijing Environmental Monitoring Corps and the Fengtai District Environmental Monitoring Detachment responded quickly and conducted an on-site inspection of the wastewater disinfection treatment process of the Huaifang Regeneration Water Plant, which treats wastewater generated in the new epidemic area.
The director of Beijing Drainage Group Huaifang Renewable Water Plant Fu Wei said that in order to strengthen the disinfection of epidemic-related sewage, Huaifang Renewable Water Plant has opened all 6 channels of the disinfection process at full load. By extending the reaction time, the disinfection effect and water environment safety are guaranteed. Encrypted water quality monitoring, shortened from twice a week to once a day to prevent secondary disasters.
According to reports, the Huaifang Regeneration Water Plant currently uses three combined disinfection processes, including ozone, ultraviolet, and sodium hypochlorite. In the sterilized wastewater, the fecal coliform index is less than 2, which meets the Beijing local emission standards.
"Over the past few days, the effluent quality of Huaifang Renewable Water Plant has reached a stable standard." Fu Wei said that after receiving the epidemic notification, Huaifang Renewable Water Plant increased the dose of combined disinfection. The ozone dose was increased from 2 mg per liter to 2.5 mg per liter. The disinfection dose of the disinfection channel was increased from 38 millijoules to 50 millijoules. The final clean water tank was controlled by chlorine supplementation to control the residual chlorine in the effluent to 0.2 mg per liter to ensure the overall disinfection effect.
During the on-site inspection process, the law enforcement personnel of the Beijing Environmental Supervision Corp. conducted on-site verification of the online monitoring data of the reclaimed water plant.
Si Hongxing, deputy head of the environmental monitoring detachment of the Fengtai District Ecology and Environment Bureau, said that the detachment made rapid response deployment to the sudden outbreak, monitored the discharge of waste water in the newly developed area, and monitored the solid waste and temporary separation points in Fengtai District. Supervise the waste water, monitor and monitor the sewage treatment plants in the whole area of Fengtai to ensure that the effluent quality meets the standard discharge, and ensure that the solid waste should be collected and legally disposed.
Cai Jinna, head of the second law enforcement department of the Beijing Environmental Monitoring Corp., said that the PH value, COD, ammonia nitrogen, total nitrogen, and total phosphorus of the Huaifang Renewable Water Plant all met relevant standards in Beijing. During the outbreak, the Beijing Municipal Environmental Protection Law Enforcement Department supervised and combined on-line monitoring and on-site law enforcement to conduct on-site inspection and supervision of key regions and key industries to prevent secondary environmental disasters.
