| Abstract:An equipment based on molecular separation technology consisting of three parts of pretreatment system, electrolytic cell and power mechanism was introduced, and its structure, operation method, the principle were described in detail. Then the equipment was used for the advanced treatment of paper mill wastewater, the results showed that the effect of the equipment used for the treatment of paper mill wastewater was remarkable, the removal rate of CODCr was over 95%, colority, BOD5 and AOX were all up to over 98% only in 20 min, at the same time, the kinds of organic compounds were greatly reduced, highly toxic macromolecular substances could be completely removed or degraded into low molecular weight organic acids. The equipment using electric energy in the treatment of paper mill wastewater pollutants, which was environmentally friendly and energy saving, in addition, the cost of wastewater treatment could be reduced due to less energy consumption during its processing, last but not the least, the secondary pollution could be avoided. |
