Slaughterhouse Wastewater Treatment Project

This project is a wastewater treatment facility for a slaughterhouse, treating the high-concentration organic wastewater generated during slaughtering. Targeting the characteristics of high blood content and high COD and ammonia nitrogen concentration, it adopts a "pretreatment + anaerobic + aerobic" process, achieving stable compliant effluent.

Fried Food Production Wastewater Treatment Project: Achieving Stable Compliance Discharge with "Pretreatment + Biochemical" Process

A food factory in Anqiu specializes in fried foods (fried eggplant boxes, small crispy pork, etc.). Its production wastewater contains pollutants such as broken leaves, minced meat, starch, protein, and fat, and has the characteristics of good biodegradability and few toxic and harmful substances. Considering the working conditions of large water quality fluctuations and oil- and residue-containing wastewater, this scheme adopts the main process of "pretreatment + biochemical + sedimentation": first, grease and suspended solids are removed by screens, oil separation, and air flotation; then organic matter is biochemically degraded by anaerobic + contact oxidation; finally, the effluent meets the Grade III standard of the Integrated Wastewater Discharge Standard (GB 8978-1996), with COD reduced from about 3000 mg/L to below 432 mg/L.

Park Domestic Sewage Treatment Project

This project is a centralized domestic sewage treatment facility for a park, treating the domestic sewage from its office and living areas. It uses integrated sewage treatment equipment, delivering stable effluent that meets standards and can be reused for greening and landscape replenishment, achieving water resource recycling.

Wastewater & Waste Gas Treatment Project for Harmless Treatment Center

This project is an integrated wastewater and waste gas treatment facility for a harmless treatment center, treating the wastewater and malodorous gases generated during processing. It combines wastewater treatment with waste gas treatment, achieving compliant wastewater treatment and waste gas purification to meet environmental regulatory requirements.

Pharmaceutical Wastewater Treatment Project

Waste Gas Treatment Project for Industrial Park Wastewater Treatment Station

This project is a waste gas treatment facility for a wastewater treatment station in an industrial park, collecting and purifying the malodorous gases generated during station operation. It adopts a "collection + biological deodorization" process to effectively remove hydrogen sulfide, ammonia and other malodorous substances, improving the air quality of the park and surrounding areas.

Nantong Polyester New Material Wastewater Treatment Project

This project is a wastewater treatment facility built for a polyester new material manufacturer in Nantong, treating the high-concentration organic wastewater generated during production. It adopts a combined process of "pretreatment + chemical dosing sedimentation + UASB + primary aerobic + sedimentation + secondary anoxic + secondary aerobic + MBR + RO". After advanced treatment, the effluent is reused in production, achieving zero liquid discharge and water resource recycling.
