Weifang Yuanhang Environmental Technology Co., Ltd., established in 2015, specializes in the research, development, and production of radioactive wastewater treatment equipment. Its decay tank system is primarily used in hospital nuclear medicine departments and radioactive laboratories to treat wastewater containing nuclides such as F-18 and I-131. Through tank decay and multi-level monitoring, it ensures that the radioactivity is reduced below national safety standards.

The decay tank is constructed from stainless steel, offering corrosion resistance, anti-seepage properties, and resistance to acids and alkalis. It integrates a PLC intelligent control system that supports remote monitoring, automatic sewage discharge, and abnormal alarm functions. The system employs a multi-tank parallel design to accommodate the storage needs of nuclides with different half-lives. It is equipped with a cutter pump for preprocessing solid residues and includes an automatic sampling module at the end to ensure compliant discharge.

The company provides one-stop services from solution design and equipment customization to construction and debugging. Typical projects include a three-level stainless steel tank system in the underground first floor of a hospital, featuring a 6m3 total volume parallel design. This enables automated monitoring and discharge recording, meeting regulatory requirements such as the "Water Pollutant Discharge Standards for Medical Institutions."
