Coal chemical wastewater case
Coal chemical enterprises generate a large amount of chemical wastewater during production, including gasification wastewater, coal-to-olefins (MTO) wastewater, wastewater from olefin production units, and domestic sewage. The wastewater usually contains complex organic pollutants such as polycyclic aromatic hydrocarbons, phenols, and biphenyls, making wastewater treatment challenging.
Project Overview: A coal chemical wastewater treatment project with a treatment scale of 25000 m³/d. Membrane module selection: GMBR flat sheet membrane, model GM480-3454, quantity 140 sets, 67200 square meters, flux 0.37 m³/m²·d
Design influent water quality:
Process flow
Membrane process parameters
Submerged MBR membrane modules are installed in the membrane pool. The membrane has a pore size of 0.25 μm and a water production rate of 170~180 m³/set·d. There are 14 membrane pools, each with 10 membrane modules. Each membrane module has a membrane area of 480 m², and the total membrane area is 67200 m².
The GMBR process can achieve continuous and stable operation, solving problems such as large land occupation, large excess sludge production, and low removal efficiency in traditional biological treatment processes. It has broad application prospects.
