A. Project background: facing the problem of catering wastewater treatment

The commercial area of the Sichuan Yibin Liya Chengyue Plaza Oil Separation Improvement Project is concentrated in catering businesses, which generates a large amount of catering wastewater with complex composition every day. This type of wastewater contains high concentrations of animal and vegetable oils, food residues and easily emulsified hot pot base ingredients. If not handled properly, it can easily cause pipeline blockage, emit odors, and pose a threat to the Yangtze River water environment. The project urgently needs a professional solution that can handle catering oil and water stably and efficiently.

B. Solution: Separation system tailored for catering wastewater

We abandoned the traditional grease trap and provided a set of deeply customized "Catering Oil and Water Integrated Grease Separation and Pumping System". Its design directly addresses the core pain points of catering wastewater:

Three-stage deep separation to overcome emulsified oil:

        First level slag removal:The automatic grille first intercepts solid debris such as vegetable leaves and meat residue to prevent subsequent blockage.

        Secondary gravity oil separation:The wastewater enters the slow flow separation zone, and most of the floating oil naturally floats and separates due to the density difference with water.

        Three-stage coalescing air flotation:For the stubborn emulsified oil produced in hot pots and stir-fries, special coalescing plates and micro-bubble air flotation technology are used to force the fine oil droplets to aggregate, become larger and float quickly, achieving deep separation and ensuring clear water.

Fully automatic and intelligent operation, liberating manpower:

The system integrates intelligent sensors and control units to achieve "automatic slag removal, automatic oil discharge, and automatic lifting."

The heating function ensures that grease does not solidify at low temperatures; the dual pump backup ensures uninterrupted sewage discharge. The entire process requires basically no manual intervention, and is particularly suitable for long-term operation and maintenance of the catering industry.

C. Implementation effect: stable operation and significant benefits

Since the equipment was put into operation, clear results have been achieved:

    Emissions continue to meet standards:The oil content and suspended matter concentration of the treated effluent are far lower than the national and municipal pipe network discharge standards, completely eliminating the risk of pipeline blockage.

    Save worry and effort in operation and maintenance:Fully automated control frees personnel from daily cleaning and inspections, reducing operation and maintenance costs by more than80%, and there is no peculiar smell on site, ensuring the quality of the commercial environment.

    A win-win situation for environmental protection and business:While strictly fulfilling environmental protection responsibilities and protecting the ecology of the Yangtze River, the stable operation of the system provides a reliable guarantee for the normal operations of catering merchants and avoids the risk of business closures caused by drainage problems.

D. Summary

This project successfully verified the effectiveness of a specialized oil-water separation solution based on the characteristics of catering wastewater. With its efficient separation capabilities, stable automated operation and significant operation and maintenance advantages, this integrated equipment has become a reliable choice for solving oil and water treatment problems in commercial complexes, food courts and other catering areas.
