摘要:
针对净水厂污泥(WTPS)直接应用于富营养化水体除磷过程中存在向水体释放氨氮和有机物的问题,研究煅烧改性净水厂污泥(C-WTPS)制备除磷材料的可行性,考察C-WTPS的氨氮和有机物的释放情况,优化煅烧工艺参数.等温吸附试验和去离子水浸渍试验的结果表明:在煅烧温度为50~400 ℃,煅烧时间为0.5~4.0 h范围内,最佳煅烧温度为400 ℃,最佳煅烧时间为2.5 h;与WTPS相比,C-WTPS对磷的吸附量增长48.2%,氨氮和总有机碳(TOC)的释放量分别削减79.5%,71.9%,铵态氮和有机物的质量比分别削减80.5%,91.6%;C-WTPS制备除磷材料具有可行性,煅烧改性工艺不仅提高WTPS的磷吸附能力,而且大为削减了WTPS氨氮和有机物的释放量.
Abstract:
Since ammonia nitrogen and organic matter release in the process of phosphorus removal in eutrophic water by using water treatment plant sludge(WTPS), the feasibility of preparing phosphorus removal material by using calcined water treatment plant sludge(C-WTPS)was studied. In addition, the release of ammonium nitrogen and organic matter of C-WTPS was investigated, and the technological parameters were opt- imized. The results of isothermal adsorption experiments and deionized water dipping tests showed that the optimum calcination parameters were calcining temperature at 400 ℃ and calcining time with 2.5 h in the range of calcining temperature between 50 to 400 ℃ and calcining time from 0.5 to 4.0 h. Comparing with WTPS, the phosphorus adsorption capacity of C-WTPS improved 48.2%, the release capacities of ammonia nitrogen and total organic carbon(TOC)of C-WTPS were reduced 79.5% and 71.9% respectively, and the contents of ammonium nitrogen and organic matter of C-WTPS were reduced 80.5% and 91.6% respectively. Therefore, it is feasible to prepare phosphorus removal material by using C-WTPS. Calcining process not only improves the phosphorus adsorption capacity of WTPS, but also reduces the release capacities of ammonia nitrogen and organic matter significantly.
