在日常工作中,經常碰到一些“关于水净化处理”的问题,现根据自己在实际工作中的体会并参考有关文献和资料談談对这些問題的粗浅看法,不妥之处尙希务正。一、凝聚理論在水处理中,凝聚工艺是指用化学和物理方法,使水中难沉淀的胶态浑浊质与凝聚剂相互触击而结合,形成较大絮絨体沉淀折出。潭濁度在地面水中,天然浑浊度主要是悬浮着的胶性土质。固态的砂粒,密实比重大,应在水源設計中考虑预沉,因此,在本文討論之外。通过地面径流,将泥土带入水中,呈分散相,性极稳定面带負电荷,只有經化学处理才致沉淀,其对水透明度的影响叫浑浊度。凝聚剂为化学药剂,解溶于水也带与水中浑浊质
In daily work, I frequently encounter some problems concerning “water purification treatment”. Now I talk about the rough ideas about these issues based on my experiences in practical work and with reference to related documents and materials. I. Cohesion theory In water treatment, the cohesion process refers to the combination of chemical and physical methods to make colloidal turbid substances and colloidal agents that are difficult to precipitate in water and combine with each other to form a large flocculant body. The turbidity of the pond is in surface water, and the natural turbidity is mainly suspended colloidal soil. Solid sands, with a large specific gravity ratio, should be considered for pre-sinking in the design of water sources, and therefore are discussed outside of this paper. Through surface runoff, the soil is brought into the water and is in a dispersed phase. The surface is extremely stable and negatively charged. Only chemical treatment can cause precipitation, and its effect on water transparency is called turbidity. Agglomerating agent is a chemical agent, dissolved in water and turbid substance in water
