针对常规饮用水过滤工艺中,石英砂滤料吸附水体中有机物质能力较弱、反冲洗周期较短的弊端,研究了利用新型滤料———活性无烟煤,原位替代石英砂过滤的整改措施。并以深圳市大冲水厂、东湖水厂沉淀池后出水为研究对象,开展小试、中试过滤试验,对比分析活性无烟煤过滤性能。实验 Aiming at the disadvantages of conventional drinking water filtration process, the ability of quartz sand filter to adsorb organic substances in water body is weak and the backwash cycle is short, the rectification measures of using new filter material --- active anthracite to replace quartz sand in situ are studied . Taking the flushing water from Shenzhen Dachen Factory and Donghu Water Plant as the research object, the pilot-scale and pilot-scale filtration tests were carried out to compare and analyze the filtration performance of the active anthracite coal. experiment
