Novel Quantitative Evaluation of Biotreatment Suitability of Wastewater

The development of wastewater treatment industry has gradually entered the high-standard period and technology needs to be refined for different types wastewater. Traditional water quality indicators are not able explain new problems encountered in current process, especially potential removing pollutants via biological methods. This research proposed a method evaluating process by measuring oxygen consumption biodegradation on-the-go describing complete process. biodegradability from an actual textile plant was quantitatively evaluated analyzing proportion organic pollutions. Results showed that hydrolytic acidification can improve increasing content biodegradable matter (growth 86.4%), air flotation little effect on Moreover, could improved nitrogen phosphorus content, which come urea K2HPO4. Concretely, source mainly increases rapid bio-treated easy 14.94% 70.79%, 143.75%. We found optimum concentration additional N P 35 mg/L 45 mg/L, respectively. approach holds great application prospects such as risk control, optimizing technology, management, due its characteristics being simple, use, online implement action.
