| Abstract: | An engineering example was introduced in which biological treatment,two stage filtration and reverse osmosis process were applied to treat urban sewage for circulating cooling water and source water of boiler make-up water treatment system of the thermal power plant,whose designing ability was(9 600 t/d.) The function and characteristics of the key technological units were also investigated.The operational results showed that the process was reliable and the effluent quality could meet the index requirement... |
