羊栖菜增殖对近海餐厨废水营养盐吸收的初步研究

Preliminary Study on Influences of Hizikia fusiforme Multiplication on Nutrient Absorption of Coastal Restaurant Wastewater

试验初步研究了大型海藻羊栖菜增殖对允泊湾近海餐厨废水营养盐的原位处理,通过分析羊栖菜对海水营养盐的吸收,发现羊栖菜对餐厨废水中N、P有明显的吸收效果。2015年2~4月羊栖菜增殖期间,试验藻区海域COD含量从140.3 mg/L下降到65.7 mg/L,减少53.2%;NH_4-N含量从0.35 mg/L下降到0.24 mg/L,减少31.4%;P含量从0.22 mg/L下降到0.07 mg/L,减少68.2%。这表明大型海藻的增殖对于近海餐厨废水的原位处理有重要的作用。

The influences of Hizikia fusiforme multiplication on in situ treatment of restaurant wastewater in coastal waters were preliminary studied in Yunbo Bay. The results showed that Hizikia fusiforme had good uptake effects on N and P in wastewater. During the Hizikia fusiforme multiplication from February to April in2015,the COD content in waters of experimental plot decreased from 140. 3 mg / L to 65. 7 mg / L,which decreased by 53. 2%; the NH_4- N content decreased from 0. 35 mg / L to 0. 24 mg / L,which decreased by31. 4%; the phosphorus content decreased from 0. 22 mg / L to 0. 07 mg / L,which decreased by 68. 2%. It indicated that Hizikia fusiforme multiplication played an important role on in situ treatment of restaurant wastewater in coastal waters.
