According to the requirements of the "Measures for Self Monitoring and Information Disclosure of National Key Enterprises" document (Huan [2013] No. 81) issued by the Ministry of Environmental Protection, our factory has taken active action and formulated the "2020 Self Monitoring Plan for the North Sewage Treatment Plant in Suma Park", which has been submitted to the Environmental Protection Bureau of Suzhou City.
Our factory has determined the self testing items for COD and ammonia nitrogen in the inlet and outlet water according to the requirements. In terms of administrative management, we have established a self testing implementation leadership group led by the factory director for the northern sewage treatment plant in Suma Park. The group consists of four technical and equipment personnel from the factory, all of whom have participated in relevant technical training at the provincial and municipal levels and obtained relevant certificates.
According to the requirements of the city, our factory has signed a technical service agreement with Anhui Bishui Technology Company for self testing. A third party will ensure the validity, timeliness, and safety of the self testing data. Our factory has a dedicated person responsible for technical communication and support with the technical personnel of Bishui Company. Anhui Bishui Technology Company strictly uploads monitoring data at a frequency of every 2 hours to ensure independence. Our factory has two laboratory staff members who conduct manual testing. They have formulated the "Detailed Rules for COD and Ammonia Nitrogen Testing of the North Sewage Treatment Plant in the Su Ma Park", which tests the water quality entering and leaving the plant every day, and regularly compares the data with their own online monitoring. Other indicators are entrusted to Anhui Guolan Testing Technology Service Co., Ltd. for manual monitoring. From the comparison of the past three months, it can be seen that manual and automatic detection errors are similar and mutually supportive, effectively ensuring the accuracy of data. In terms of implementation methods, it can be confirmed that the collection of COD, ammonia nitrogen and other data is scientific, effective and accurate, thereby ensuring the discharge requirements of the effluent quality of the sewage treatment plant.
