A Study On Profound Processing Waster Of Sewing Plant As Feed Water For Elctricity Boiler

Pretreatment technique of feed water for thermoelectricity boiler from profound processing water is studied, and then active carbon adsorption of low density organic wastewater is analysised. We can get following results:1. We study the pretreatment technique of feed water for thermoelectricity boiler from profound processing water. This can reuse profound processing water from sewage plant as water supply and it can largely benefit our society and environment.2. In our study, after active carbon adsorption-electro-dialysis de-salt treatment, we get the water that thermoelectricity boiler quality of de-salt techniques very well: CODMn<3mg/l, turbidity<1 NUT, chroma<1, anion surface-active agent<0.5mg/1, total bacteria<100/ml, Fe<0.3mg/l.3. Electro-dialysis can effectively remove the ions in the wastewater. After electro-dialysis, the sailnoness and total hardness of the effluent can decrease to 260~280mg/l and 100mg/1. And from the experiments we can get the working electricity as 0.3A, the feed quantity as 2001/h.4. After active carbon adsorption-electro-dialysis de-salt treatment, we can verify that: all the index of the regenerated can meet the thermoelectricity boiler quality of de-salt techniques very well. And the working period of the pretreatment is increased from 13h to 19h.
