| 摘 要： | 研究了混凝剂对牛沼液的净化效果,选择最佳处理工艺,为畜禽废弃物厌氧发酵沼液的循环利用和安全排放提供科学依据。采用3种混凝剂、1种助凝剂,分别对牛沼液进行混凝试验,用矾花的形成、大小、沉降速度、浊度和CODcr值及其去除率评价其净化效果。结果表明:以氯化铁(320mg·L-1)二次混凝的效果最好,矾花形成最快且相对最大、浊度为119.4 NTU,COD值为260mg·L-1。将处理污水的混凝工艺技术应用在牛沼液的净化处理中,取得了良好的净化效果,有望达到国家畜禽养殖业污染物排放标准。

| Abstract: | Three coagulants and a coagulant aid were involved in a purification process of cattle biogas slurry. An experiment by three coagulants and a coagulant aids were carried out on the cattle biogas slurry with the form of floe, floe size, sedimentation of floe, mea- suring turbidity and CODcr. The results showed that there was a different degree of purification for cattle biogas slurry during the combinations test, and the most efficient combination test was ＂coagulation in two times at 320 mg. L-1 ferric chloride＂. It was available that the treatment approach of sewage was applied in cattle biogas slurry of anaerobic fermentation. |
