孔石莼对养虾废水营养盐吸收的研究
Study on Nutrients Absorption of Shrimp Effluents by Ulva pertusa Kjellm
摘要
Abstract
The paper emphasizes the study on water purification effect of Ulva pertusa Kjellm in shrimp effluents with different concentration.According to the research,Ulva pertusa Kjellm proved to be effective in removing nutrient N and P.The removal of NO3--N was around 99.8％,NO2-N 99.6％,NH4+-N 95.9％,PO43--P 98.7％ and DIN 98.6％.Ulva pertusa Kjellm was able to absorb NH4+-N as well as NO3--N and NO2--N.The major difference between two nutrients was that the absorption of ammonia nitrogen could be rapidly completed in the first day while nitrate nitrogen was absorbed mostly in two or three days.Ulva pertusa has achieved health growth in the shrimp effluents with a satisfactory daily growth rate and maintained the steady increase in the fresh weight.关键词
