针对黄河下游地区胜利油田引黄水库水源水高藻、高有机物等污染现状,以氯气、高锰酸钾复合药剂、稳定性二氧化氯等作为预氧化剂,开展了组合原水预氧化试验研究,同时以氯气、稳定性二氧化氯作为消毒剂,开展了出厂水组合消毒应用试验研究。研究结果表明,在合理的药剂投量范围内,采用稳定性二氧化氯预氧化和消毒工艺可有效控制消毒副产物指标,其出厂水三卤甲烷总量等指标显著降低,饮水口感明显改善,出厂水各项水质指标均稳定低于国标限值,稳定性二氧化氯可取代传统的氯气消毒,应用前景良好。
Aiming at the status of high algae, organic matter and other contaminants in the water source water of the Yellow River reservoir in the Lower Yellow River, the combination of chlorine, potassium permanganate, chlorine dioxide and other stability as a pre-oxidant, Chlorine, chlorine dioxide as a stability as a disinfectant to carry out a combination of factory water disinfection experimental study. The results showed that the indicators of disinfection by-products were effectively controlled by the stable chlorine dioxide pre-oxidation and disinfection process within the reasonable dose range of pharmaceuticals. The indicators of the total amount of trihalomethanes in factory water were significantly reduced, the taste of drinking water was significantly improved, All water quality indicators of the factory water are stable lower than the national standard limit, the stability of chlorine dioxide can replace the traditional chlorine disinfection, the application prospect is good.
