Abstract

Abstract:

In view of the poor performance of Fe and Al coagulants in deep phosphorus removal in low temperature and low turbidity water，based on the specific affinity of lanthanum and phosphate，a series of polylanthanum coagulants（LXC） were prepared by sol-gel method with different lanthanum sources，organic ligands and raw materials（acid，alkali，alcohol，water）.The mass fraction of lanthanum in the obtained materials was 30%~33%，and the particle size of the coagulation floc reached 1 600 μm.And the settlement process could be completed within 5 minutes.The deep phosphorus removal and turbidity removal performance of LXC on university river water［temperature of 4~6 ℃，phosphorus concentration of（1.0±0.1） mg/L］，Yangcheng Lake water［temperature of 4~6 ℃，phosphorus concentration of （0.1±0.3） mg/L］，and Shihu Lake water［temperature of 4~6 ℃，phosphorus concentration of （0.8±0.2） mg/L］ were evaluated using LaCl₃ and polyaluminum chloride（PAC） as control samples.The results showed that under the same dosage，LXC had better phosphorus removal performance on different water samples than LaCl₃ and PAC.Under suitable conditions，the residual phosphorus concentration in the coagulated effluent was less than 0.02 mg/L，achieving deep phosphorus removal performance.This study provided new solutions for deep phosphorus removal and alleviating eutrophication in wave.

Key words: coagulation, polylanthanum coagulants, low temperature and turbidity, phosphorus removal, sol-gel method
