In recent years, winter water treatment plant effluent quality in Baotou is abnormal. In order to investigate the causes of affecting the water quality. After a year water quality monitored parameters of the waterworks source and combined with algae lab laboratory testing, counting. Analyzeed water quality status and the relationship between the parameters. Obtained water had been polluted. In the...
Park lake water in urban is playing an important role in urban environment and residents' life, but as a result of its characterizes including independence, slow fluidity and the use of reclaimed water and rainwater run-off as supplement water, it tends to be vulnerable to the outbreak of water bloom. However, pretreatment could be done towards reclaimed water and rainwater runoff into the independent...
Reclaimed water reused for landscape was prone to algal bloom as well as health issues. Low concentrations of nitrogen and phosphorus in landscape water were effective to prevent algal bloom. In this study, "GFH+BF" treatment system was used to control reclaimed water quality for landscape. Integrating physical and chemical indicators with biological analysis method, the quality of artificial...
During the last two years, data sets from three groups and twelve sampling points were used to investigate historical changes between the concentration of the cyanobacteria and the concentrations of total nitrogen (TN), total phosphorus (TP), TN/TP, chemical oxygen dawdling (COD), NO3-, pH, and Chl-a in a shallow temperate zone lake (Guishui Lake, Beijing). The aim of this paper was to evaluate changes...
The landscape of reclaimed water always broke out water bloom because of containing high concentrations of nitrogen and phosphorus. The TP and TN of the landscape decreased to 0.04 mg/L and 2.27 mg/L respectively with recycling ozonation at the end of the experiment. Chlorophyll a was 94.3 mg/m3 and CODCr was 45.1 mg/L. Ozonation could inactivate the algae but not destroy the cell completely. Comparing...
A 4-month data set was used to investigate historical changes between the number of the Cyanobacteria and concentrations of total nitrogen (TN), total phosphorus (TP), TN:TP, chemical oxygen dawdling (COD), NO3, pH and Chl-a in a shallow temperate zone lake (Guishui Lake, Beijing, China). The aim was to evaluate changes in the risk of Cyanobacteria blooms, which have occurred several times in the...
Based on the analysis of the water quality monitoring data of Xingkai Lake in 2008, the eutrophic level of the water body was evaluated through a comprehensive trophic state index method. The results showed that the comprehensive trophic state index (CTSI) was 47.7 for Da Xingkai and 50.1 for Xiao Xingkai, which indicated that Da Xingkai is in a mesotrophic state and Xiao Xingkai in a light eutrophic...
