ADVANCED TREATMENT OF ORGANIC WASTE WATER

摘要

PURPOSE:To provide an advanced treatment method of an organic waste water by RO membrane filter device capable of drastically increasing the yield of a treated water. CONSTITUTION:The organic waste water is fed to the RO membrane filter device 3 from the recycle tank 1 as the raw water for membrane filtration to be separated into the condensate and the treated water in cross-flow. And when COD of the condensate comes to >=30mg/L, the passage of the condensate is switched and the condensate is treated with the MnO2 treatment 4 and the ion exchange treatment 7 as the condensate to be treated and is returned to the recycle tank 1.
