A few days ago, the Zhuji Branch of the Shaoxing Municipal Ecological Environment Bureau found that since March 2021, a printing and dyeing company in Zhejiang has been experiencing abnormal phenomena of regular fluctuations when checking the historical data of wastewater automatic monitoring flow.

After further analysis, law enforcement officers found that the company’s average daily sewage discharge since the end of 2020 Gradually increasing, by March 2021, the average daily sewage discharge increased by nearly 50%. However, the company’s corresponding sewage treatment facilities have not expanded or modified the capacity, and it is inferred that it may have illegal sewage discharge behavior.
On April 6, 2021, the law enforcement officers of Zhuji Branch and the public security conducted a surprise inspection of the company and found that the on-site situation was completely consistent with the data research and analysis. Law enforcement officers conducted overnight inquiries and investigations on the management and operators of the company’s sewage treatment station.
The results of the investigation are as follows: Since the end of last year, due to the increase in business orders, the amount of sewage discharged by this company has exceeded the processing capacity of the existing sewage treatment facilities. In order to avoid the automatic monitoring system of pollution sources, the company uses manual operation of the lifting pump and main valve to control the concentration of sewage, so that the COD concentration in the automatic monitoring data always remains around 170 mg/L, while the actual sampling test is 343 mg/L, which exceeds the “Textile Dyeing and Finishing” Industrial Water Pollutant Discharge Standards set the limit value requirements, and the exceeding rate reached 71%.

This behavior violates the provisions of the Supreme People’s Court and the Supreme People’s Procuratorate on the application of handling criminal cases of environmental pollution. The provisions of Article 1, Item (7) of the Interpretation of Certain Legal Issues. At present, the public security organs are still continuing to investigate the case, and the three main suspects have been criminally detained.

Summary and inspiration
ΔIntelligent Supervision Platform
This case was investigated by the Ecological Environment Department Based on big data analysis and judgment to identify clues to illegal pollution discharge, joint investigations with public security organs were carried out, and cases of interference with automatic pollution source monitoring facilities and excessive discharge of pollutants were discovered. It is necessary to promote “off-site” supervision methods with “digital empowerment”, strengthen the analysis and judgment of ecological environment data, and improve the ability to detect environmental problems.
