摘要:
为探究本课题组合成的一种双十二烷基γ-双季铵盐(简称CP16)杀生剂的杀藻性能及机制,考察了不同投药量、光照条件对铜绿微囊藻和小球藻的去除效果,通过与聚合氯化铝对比,分析推测了杀藻机理。结果表明:当CP16投加量为5 mg/L时,铜绿微囊藻和小球藻浊度在第7 d时能达到最低值,去除率分别为50.91%和10.98%,且15 d时能保持较低水平; 当投加量为5～15 mg/L时,1 d后,铜绿微囊藻和小球藻藻液的OD420值均比初始藻液低,且15 d后仍维持在较低值,没有增长的趋势,CP16对铜绿微囊藻和小球藻的叶绿素a(Chla)去除率可高达100%; 加入5 mg/L CP16后,在全光照和光暗周期为12 h:12 h光循环条件下,CP16对藻类生长的抑制效果较好,去除率均能达到99%。CP16为对称型阳离子双季铵盐,具有水溶性聚季铵盐特性,CP16通过其自身特殊分子结构,通过絮凝、吸附、毒性作用促使藻细胞变性死亡。CP16的特殊结构使其具有较强的杀生活性,既能实现杀藻的效果,又不会形成生物积累效应。CP16因为其较好的除藻效果和特殊结构,具有很好的发展前景。
Abstract:
In order to explore the algicidal performance and mechanism of a new kind of didecyl γ - diquaternary ammonium salt(CP16)biocide, the removal effect of different dosage and light conditions on Microcystis aeruginosa and Chlorella pyrenoidosa were investigated. The mechanism of killing algae by CP16 was analyzed and speculated by comparing with polyaluminum chloride. The results showed that when the concentration of CP16 was 5 mg/L, the turbidity of microcystis aeruginosa and chlorella pyrenoidosa reached the lowest value on the 7th day, and the removal rates were 50.91% and 10.98% respectively, and the turbidity remained at a low level on the 15th day. When the dosage was 5—15 mg/L, the OD420 of microcystis aeruginosa and chlorella pyrenoidosa were lower than that of the initial blank one day later, and remained at a low value after 15 days without increasing trend. The Chla removal rate of CP16 to microcystis aeruginosa and chlorella pyrenoidosa was as high as 100%. After adding 5 mg/L CP16, the inhibition effect of CP16 on algae growth was better under the conditions of full light and dark 12 h:12 h photocycle, and the removal rate could reach 99%. CP16 is a symmetrical cationic bisquaternary ammonium salt, which has the characteristics of water-soluble polyquaternary ammonium salt. CP16 promotes the degeneration and death of algae cells through its special molecular structure, flocculation, adsorption and toxicity. The special structure of CP16 makes it have strong killing activity, which can not only achieve the effect of killing algae, but also not form the effect of bioaccumulation. CP16 has a good development prospect because of its good algae removal effect and special structure.
