【摘要】：黄粉虫生长过程中会产生大量的虫蜕、死虫和蛹壳等废弃物,将这些废弃物制备成黄粉虫壳聚糖并用于养殖废水的处理,通过单因素和正交实验,优化了废水的处理条件。结果表明,采用黄粉虫壳聚糖与Fe2(SO4)3复配,对养殖废水有较好的净化效果。较优的处理条件为:养殖废水250 m L,壳聚糖15 mg与5 m L 2%Fe2(SO4)3复配,定容至1 L(p H为中性)。该复配体系对实际养殖废水的絮凝率达93.2%,对总悬浮物、氨氮、总有机碳、总氮的去除率分别达到93.75%、75.60%、73.14%和41.92%。
[Abstract]:In that proces of the growth of the yellow powder, a large amount of waste such as worm, dead worm and pupae is produced, and the waste is prepared into the yellow powder and the chitosan and used for the treatment of the culture wastewater, and the treatment conditions of the wastewater are optimized through the single factor and the orthogonal experiment. The results showed that the compound of chitosan and Fe2 (SO4) 3 was used to purify the wastewater. The better treatment conditions are as follows: the culture wastewater is 250m L, the chitosan 15 mg is compounded with 5 m L 2% Fe 2 (SO4) 3, and is set to 1 L (p H is neutral). The removal rate of the total suspended matter, ammonia nitrogen, total organic carbon and total nitrogen was 90.75%, 70.60%, 73.3. 14% and 41. 92%, respectively.
