This present disclosure relates to a highly effective sewage treatment based on regulation and control of directed electron flow and apparatus thereof The apparatus includes an anaerobic fermentation electron generation chamber, a heterotrophic-autotrophic denitrification chamber and an aerobic membrane separation chamber. Low concentrated organic sewage is introduced into anaerobic fermentation electron generation chamber; then, particulate and partly dissolved organic substances are intercepted and absorbed by carrier materials; and extracellular currents generated by microorganism reaction are used in following autotrophic denitrification processing. Micro-/ultra-membrane separation processing is used to improve operation load and solid-liquid separation effect of sewage treatment and thereby effluent could meet the high recycling standards. The directed electron flow is regulated and controlled to enhance nutrients removal and to reduce sludge yield and fouling rate of membrane. The sewage treatment could efficiently treat low concentrated organic sewage at normal temperature (>15 C.) and dramatically decrease energy consumption.

The present invention relates to a method for inhibiting the formation of dioxin-like compounds in solid waste incineration flue gases, belonging to the field of cleaning of solid waste incineration flue gases. In accordance with the present invention, when incineration flue gases cool down to 500450 C., the flue gases are introduced into an inhibition reactor where copper chlorides in flue gas particulates mix and react with inhibitors to convert into copper metaphosphate so as to inactivate the copper chlorides which can catalyze the formation of dioxin-like compounds and control dioxin-like compound pollutants in incineration flue gases at the source. Compared with the prior art, the invention can effectively control the main formation ways of dioxin-like compounds in solid waste incineration flue gases by optimizing inhibitors and reaction conditions. The method of the invention does not affect the residual heat utilization of solid waste incineration flue gases, so solid waste incineration has a better resource utilization effect. The ammonium dihydrogen phosphate inhibitor used in the invention has the advantages of high inhibition efficiency, strong operability, low cost and environment protection, providing the technology with good application feasibility.
