2 algae - Skeletonema costatum (SC) and Prorocgntrum micans (PM) were investigated for the influence on the reproduction of Calanus sinicus. Fatty acids produced by phytoplankton were detected with GC-MS analysis method. The results showed that, compared with PM, SC induced inhibitory effects on egg production of Calanus sinicus. By the analysis of fatty acids, the values of total content of fatty...
Iron-enhanced activated sludge was developed to solve the problem that the nitrification efficiency was poor in low temperature. Removal efficiency of CODCr, NH4+-N and PO43-P by iron-enhanced activated sludge were investigated by using integrated biological reactor in common temperature and low temperature. And the transformation law of nitrogen and phosphorus treated by iron-enhanced activated sludge...
