    Peer-reviewed report for Accele-tech’s proposed plans about waste water and gas treatment of Shanghai Huiguang Fine Chemical Industry Company


    Pilot Project Two

    Peer-reviewed report for Accele-tech’s proposed plans about waste water and gas treatment of Shanghai Huiguang Fine Chemical Industry Company

    On April 11, 2017, Environmental Science and Engineering College of Donghua University conducted a technical review relating to Accele-tech’s proposed plans under the commission by Shanghai Huiguang Fine Chemical Industry Company.
    The committee members include: Professor Jiangcheng Xu (expert in environmental field) from Environmental Science and Engineering College of Tongji University, Professor Gang Xue (dean of college) from Environmental Science and Engineering College of Donghua University, and Professor Hong Tao from Environmental and Architectural College of University of Shanghai for Science and Technology.

    Comments from the expert committee


    1.Proposed plan for waste water treatment system
    1)All necessary and related documents are complete and meet the requirement.
    2)The project uses Accele-tech’s biological fluidized bed technique and unique salt-tolerant bacteria to treat saline wastewater. The treated wastewater then enters the western wastewater treatment plant and finally is discharged into Hangzhou Bay. The salinity in discharged water is much less concentrated than seawater’s. In comparison with evaporation and crystallization process, Accele-tech’s process does not generate secondary pollution and causes less ecological impact. Therefore, the proposed plan well solves the bottleneck for saline wastewater biochemical treatment problem.
    3)The project adds a pretreatment unit for concentrated wastewater and Accele-tech’s advanced integral treatment equipment besides the traditional process units. The whole process can improve biodegradability and increase the capacity for biochemical system to resist impact load.
    4)The project employs Accele-tech’s advanced integral treatment technique including electrocatalysis to better maintain a balance in salinity in wastewater treatment system.
    2.Proposed plan for waste gas treatment system
    1)All necessary and related documents are complete and meet the requirement.
    2)The project adds the Accele-tech’s multiphase catalytic reactor unit besides the original process units to convert waste gas to waste water treatment. The unit includes biological filter and activated carbon adsorption equipment as supplement to remove odor. By utilizing this process, the emission standard can be achieved. It is also beneficial to achieve the treatment goal for “Stable effect, and economic operation”.
    Committee members agree that the technical processes proposed by Accele-tech are innovative and feasible. Accele-tech company is able to provide technical support to Shanghai Huiguang Fine Chemical Industry Company to achieve emission standard for waste water and gas treatment. Therefore, the plans are approved.

    Technical upgrading in waste water treatment: The project adds the Accele-tech’s multiphase catalytic reactor unit besides the original process units to enrich the pollution in gas into the water phase, and the waste gas treatment can be converted to waste water treatment. Additionally, biological deodorization filter is equipped to eliminate the odour and ensure that emission standard can be achieved.
    Technical upgrading in gas treatment: Using Accele-tech’s unique salt-tolerant bacteria to treat saline wastewater,  the proposed plan well solves the bottleneck for saline wastewater biochemical treatment problem. Accele-tech’s multiphase catalytic reactor is the core equipment for pretreatment unit and Accele-tech’s advanced integral treatment , which increases the resist impact load for biochemical system and make the long-term treatment goal can be achieved.
