CNPC Chuanqing Portable Toilet

CNPC Chuanqing has mainly achieved results in portable toilets, including utility model patents and integrated environmental protection toilet material procurement.

I. Utility Model Patent Chengdu Dayou Petroleum Drilling and Production Engineering Co., Ltd. and CNPC Chuanqing Drilling Engineering Co., Ltd. Chuanxi Drilling Company jointly hold the utility model patent for 'A Mobile Environmental Protection Toilet System for Field Construction Sites'. This system adopts an integral hoisting wilderness camp structure, which is easy to move and install, enabling it to quickly adapt to the needs of field construction sites. The toilet body is divided into a usage area and a treatment area, with clear functional divisions. The usage area is equipped with flushing toilets and/or urinals, providing users with a relatively comfortable and hygienic toilet environment. The treatment area features a circulating treatment system with a control device, including in sequence a collection and separation tank, a regulating tank, an anaerobic tank, an aerobic tank, an MBR membrane tank, an activated carbon filtration tank, a facultative tank, a sand filtration tank, and a clean water tank. The collection and separation tank is located at the bottom of the usage area, and the toilets and/or urinals send the sewage to be treated into the collection and separation tank. Through this series of treatment tanks, the sewage can be effectively purified and treated. Finally, the clean water tank provides flushing water for the toilets and/or urinals, achieving water resource recycling. This is both environmentally friendly and saves water resources, making it highly suitable for field construction sites where water resources are relatively scarce.

II. Integrated Environmental Protection Toilet Material Procurement Chuanqing Well Repair Company conducted integrated environmental protection toilet material procurement in 2026, planning to purchase 10 sets of integrated environmental protection toilets. The procurement was organized in the form of entrusted bidding, with the procurement method being open bidding. By using the open bidding method, more suppliers can be attracted to participate in the competition, thereby selecting integrated environmental protection toilet products with better quality and more reasonable prices. This helps to improve the level of environmental protection facilities of Chuanqing Well Repair Company in relevant projects and meet the needs for environmental protection toilets at construction sites.
