Wastewater Treatment Project


YAJIAFU (Fujian) Foods Co., Ltd.'s wastewater treatment construction project is located at No. 158, Longxiang Road, Longhai District, Zhangzhou City, Fujian Province. The company, with a high sense of social responsibility and mission, focuses on long-term development and has always attached great importance to and strictly adhered to the principle of zero pollution in environmental protection and energy conservation and emission reduction. Therefore, the company has built and put into use the "48t/d food wastewater treatment project" in December 2016. This project passed the acceptance of the Lonhai City Environmental Protection Bureau in March 2017 and obtained the "Fujian Province Discharge Permit". With the gradual expansion of the company's market, the increase in production lines and personnel, and the gradual increase in the company's water consumption, it is predicted that the existing wastewater treatment facilities may not be able to meet the wastewater treatment standards under the subsequent long-term overload operation, which will cause pollution to the surrounding environment. In order to protect the ecological environment and improve the overall image of the enterprise, the company, with a highly responsible spirit for environmental protection, decided to expand the food wastewater treatment project construction after high-level discussions, and ensure that after expansion, the project can meet the wastewater treatment capacity required for the company's full-load production in the future. In November 2019, a construction contract for a "300t/d food wastewater treatment project" was signed with Xiamen Zhongzhi Environmental Protection Engineering Co., Ltd., with a total investment of more than 2 million yuan. The completion and use of the project ensures that wastewater treatment reaches the first-level discharge standard stipulated in GB8978-1996 "Comprehensive Emission Standard for Wastewater", as follows:

The project started expansion in December 2019, the project was completed in June 2020 and put into trial operation for three months, in October 2020, the project acceptance was qualified, and the wastewater discharge detection met the first-level discharge standard stipulated in GB8978-1996 "Comprehensive Emission Standard for Wastewater". During the subsequent nearly one-year operation period, the Lonhai District Environmental Protection Bureau conducted on-site inspections many times, and all sampling and testing were qualified, with no pollution incidents or complaints. Recently, our company commissioned Zhangzhou Kequan Environmental Testing Co., Ltd. to conduct the following data sampling and testing of our company's wastewater:

According to the above water quality test data, our company's wastewater treatment has reached the first-level discharge standard stipulated in GB8978-1996 "Comprehensive Emission Standard for Wastewater", and the water quality of all tailwater is tested to be better than the Class V surface water quality standard, according to "Water Quality for Urban Wastewater Reuse Landscape Environmental Water" (GB/T18921-2019), it can be directly discharged into surrounding water systems and used as ecological water replenishment.

Currently, it is directly discharged into the Xixi Yitiaolong Water System around our factory and has not been discharged into the municipal sewage pipeline in our district.
