Enterprises that discharge 100 tons of industrial wastewater or more than 30 kilograms of COD per day must install TOC or COD automatic monitors; Companies producing alkaline industrial wastewater must install automatic pH monitors. Automatic monitoring instruments such as flow meters, TOC, COD and PH must be approved by the environmental protection department, and their data collection and transmission must be networked with the pollution source remote monitoring center of the Rugao Environmental Protection Bureau. Exhaust signboards are supervised and produced by the municipal environmental protection department, and the costs are borne by each enterprise.

4. Enterprises that build TOC or COD monitors must build an automatic monitoring room (an area of ??about 8 square meters) in accordance with the unified requirements of the park. The keys are provided by the entrusted operator and the environmental protection department or authorized by the operator. sewage treatment plant.

5. Each enterprise’s TOC, COD online monitors, PH automatic monitors, and sewage flow meters shall be entrusted to units with maintenance qualifications for daily maintenance and management to ensure normal operation, and an entrusted maintenance management contract shall be signed. , maintenance and management costs are borne by each enterprise.

6. For those who violate relevant regulations and cause TOC, COD online monitors, PH automatic monitors, sewage flow meters and other automatic monitoring equipment to not operate normally; or who intentionally deactivate, dismantle or replace automatic monitoring equipment without authorization , it will be regarded as intentional abnormal use of pollution control facilities, and the environmental protection department will handle it in accordance with relevant laws and regulations.

7. In order to facilitate monitoring and sampling, each enterprise must set up a public supervision well for rainwater (including indirect cooling water) outlet outside the enclosure wall. The public supervision well must be constructed in accordance with the unified requirements of the environmental protection department.

5. Measurement of sewage

The measurement of sewage is based on the measurement data of the flow meter installed at the sewage outlet. The measuring instruments must be regularly sent to the measurement department for verification according to regulations.

VI. Monitoring and monitoring of sewage

1. The sewage treatment plant has set up a pollution source automatic monitoring sub-center, and each enterprise has online sewage flow meters, TOC or COD monitors, PH monitors, etc. The equipment must be networked with the pollution source automatic monitoring sub-center.

2. The development zone implements a combination of manual monitoring and instrument monitoring in the online monitoring system. If there is a deviation, the data tested by the environmental monitoring station shall prevail.

3. The sewage treatment plant implements an irregular monitoring frequency of twice/day for enterprises with continuous drainage. Enterprises that discharge water in batches or intermittently shall carry out batch monitoring, and only those who pass the test can discharge water.

4. The environmental monitoring department’s monitoring data of various types of sewage discharged by enterprises in the area serve as the basis for the administrative law enforcement of the environmental protection department.

5. When the sewage treatment plant conducts monitoring and sampling, it is necessary to take three sewage samples at the same time. The sewage treatment plant and the sewage discharge enterprise each test one and keep one. If the deviation between the monitoring data of both parties is less than 20%, the average value of the monitoring data of both parties will be the final monitoring data; if the deviation of the monitoring data of both parties is greater than 20%, the Rugao Environmental Monitoring Station will be entrusted to conduct analysis, and the analysis result will be the final monitoring data. Monitoring costs are paid by the party with larger data deviations.
