为了寻找一种工艺简单、设备耐用、操作管理方便的净水工艺 ,对多级粗滤料滤床慢滤综合净水工艺进行了试验研究。根据所设计的试验流程 ,对两种水质的原水进行试验。苯酚采用 4-氨基安替比林直接光度法测定 ,氨氮采用氨测定的蒸馏滴定法中的预处理方法 ,溶解氧采用碘量法测定 ,浊度用光电浊度仪测定。最终得出了多级串联粗滤成熟期有机物去除率与时间关系、氨氮的浓度变化曲线 ,并对试验结果进行了分析讨论。
In order to find a simple process, durable equipment, easy operation and management of water purification process, the multi-stage coarse filter media filter slow filter integrated water purification process were studied. According to the design of the test process, two types of raw water quality test. Phenol was determined by 4-aminoantipyrine direct spectrophotometry, ammonia nitrogen was pretreated by ammonia distillation distillation titration method, dissolved oxygen was determined by iodometric method, and turbidity was measured by photoelectric turbidimeter. Finally, the relationship between the removal rate of organic matter and the concentration of ammonia nitrogen and the concentration of ammonia nitrogen in the multi-stage serial stratified stratification stratification were obtained, and the test results were analyzed and discussed.
