| Popis: | Fugate water, when it enters the beginning of sewage treatment plants (STP), increases the load on the biological treatment system. Methods of purification of the STP return water are considered. A new composite composition has been developed for the reagent precipitation of ammonium and phosphates from water, which is formed as a result of thickening and dewatering of sludge. On the basis of the experimental data obtained, a technological scheme for the treatment of water formed after mechanical dewatering of excess activated sludge and sludge from the operation of treatment plants at biological wastewater treatment plants has been developed. The developed technological solution makes it possible to exclude the effect of aluminum on activated sludge and minimize the negative effect of ammonium and phosphates, with minimal construction and operating costs. The proposed cleaning method is applicable to both existing treatment facilities and newly designed ones. |
