【摘要】：近些年我国工农业发展迅猛,全国多地水资源遭受了不同程度的污染,以前的饮用水水源已变成微污染水源,目前国内外微污染水源水厂水质提升改造的主要技术措施有:增设预处理,加强常规处理及增加深度处理。唐山市某净水厂负责唐山市区绝大部分居民生活用水及工业企业用水,由于陡河水源受到一定程度的污染,净水厂出水水质已难以满足国家最新水质标准要求。本次工艺改造结合陡河水源水质特征及水源微污染状况,在充分研究国内外微污染水源水厂水质提升改造先进经验的基础上,提出如下水质提升改造工艺:对净水厂的取水工程增加高锰酸钾预氧化措施;将原工艺栅条絮凝斜管沉淀池改造为曝气絮凝高密度沉淀池;将原工艺双阀滤池改造为浸没式超滤膜池;改造后水厂水处理工艺为高密度混凝沉淀+生物粉炭活性泥渣回流+超滤处理工艺,利用生物活性泥渣和生物粉末活性炭的生物作用去除微量有机物,利用超滤优越的机械截留作用,高精度地去除不溶颗粒物包括浊度、细菌、病毒,保障供水水质安全,提高供水质量,为唐山市工商用户及人民群众提供安全合格的饮用水。该工程的成功经验也能为唐山市内其他微污染水源水厂水质提升改造提供参考。
[Abstract]:In recent years, China's industry and agriculture have developed rapidly, and many water resources throughout the country have been polluted to varying degrees. Previously, drinking water sources have become micro-polluted water sources. At present, the main technical measures for upgrading the water quality of micro-polluted source water plants at home and abroad are as follows: adding pretreatment, strengthening routine treatment and increasing advanced treatment. A water purification plant in Tangshan City is responsible for the water consumption of most residents and industrial enterprises in Tangshan City. Due to the pollution of Douhe water source, the effluent quality of the water purification plant cannot meet the requirements of the latest national water quality standards. Combined with the water quality characteristics of Douhe water source and the status of water source micro-pollution, this process reform is based on the full study of advanced experience in upgrading water quality of micro-polluted source water plants at home and abroad. The improvement process of water quality is put forward as follows: adding pre-oxidation measures of potassium permanganate to the water intake project of water purification plant, transforming the original technology grid strip flocculation inclined tube sedimentation tank into aerated flocculation high density sedimentation tank; The original double valve filter was transformed into submerged ultrafiltration membrane, and the water treatment process of water plant was reflux ultrafiltration process of high density coagulation sedimentation biological powder carbon activated sludge. Using biological action of bioactive sludge and biological powder activated carbon to remove trace organic matter, utilizing superior mechanical retention of ultrafiltration, removing insoluble particles including turbidity, bacteria, virus and ensuring the safety of water supply water quality with high precision. Improve the quality of water supply to provide safe and qualified drinking water for industrial and commercial users and people in Tangshan. The successful experience of the project can also provide a reference for the improvement of water quality of other micro-pollution source water plants in Tangshan City.
