Photocatalytic Degradation of Molasses Alcohol Wastewater by Lead Tungstate
Molasses alcohol wastewater is produced by molasses fermentation in alcohol workshop of sugar refinery and high concentration and high chroma organic wastewater discharged later. It riches in protein and other organic compounds, but also contains more N, P, K, Ca, Mg and other inorganic salts and higher concentrations of SO 4 2- and so on, most of these acidic waste water, and high chroma, will seriously pollute the water, the environment, or cause compaction of soil acidification, crop long illness. The main methods of treating molasses alcohol wastewater are irrigation, concentration, anaerobic and aerobic methods, biological products and EM bacteria technology, in addition to not producing biological products, other methods continue to harm the environment, or the cost is too high, unrealistic, will there be a feasible strategy for the best of both worlds? In recent years, with the development of photocatalytic technology of nano tungstate , more and more tun...
