- Abstract:
- Cyanobacteria bloom took place in a water source in the north from September 17 to October 22, 2015. By analyzing and monitoring the water quality, it was shown that the raw water had the characteristics of low temperature, high algae concentration, high turbidity and high organic (CODMn) concentration during cyanobacteria outbreak period. Natural condition and ecological environment of the reservoir area were analyzed. It was found that water eutrophication was the main cause of cyanobacteria outbreak. By adopting the measures of optimizing preoxidation process, enhancing coagulation, adjusting the operational parameters of each section and reducing running load moderately, effluent quality of the water plant could always meet the requirements of the national standard, and the water plant passed the cyanobacteria bloom period safely and smoothly.
