On June 25, 2019, our company conducted a random inspection of the Municipal Ecology and Environment Bureau and found that the water quality PH value exceeded the standard. On July 2, we received a notice of production restriction. The company has comprehensively rectified the sewage treatment facilities, and added alkali-adding machines and multiple sets of testing instruments, strengthened the environmental awareness and skills training of managers and operators, established an inspection and supervision mechanism, and re-qualified water samples for inspection. During the production limitation period, the order production was appropriately adjusted, and the output was reduced by 30%. This event thanked the leaders of the Municipal Ecology Bureau for sounding the alarm of the Conservative Law for the company, which enabled our company to achieve stable development in future scientific production management.
