Description
技术领域technical field
本实用新型涉及含油废水处理领域，具体涉及使用多级平板陶瓷膜含油废水处理设备。The utility model relates to the field of oily wastewater treatment, in particular to equipment for treating oily wastewater using multi-stage flat ceramic membranes.
背景技术Background technique
含油废水是指废水中含有较多的油类污染物以及无机盐份等其他污染因子的废水，其主要油类污染物是一定量的石油类或动植物油类，其主要来源于石油、石油化工、钢铁、焦化、煤气发生站、机械加工等工业部门。其中油类物质在废水中通常以四种状态存在。(1) 上浮油，油滴粒径大于100μm，易于从废水中分离出来。在石油污水中，这种油占水中总含油量60~80%。(2)分散油.油滴粒径介于10～100μm之间，悬浮于水中。(3)乳化油，油滴粒径小于10μm，油品在废水中分散的粒径很小，呈乳化状态，不易从废水中分离出来。(4)溶解油，油类溶解于水中的状态。目前含油废水的处理大多采用气浮、重力分离、离心分离等传统的方式进行，因为油类物质在水中有多种状态的形式存在使得传统方式对含有废水的处理效率非常有限，而且很难达到各种排放或回用水要求的标准。如果这些含油废水不加以回收处理直接排入河流、湖泊或海湾，会污染水体，影响水生生物生存；如果用于农业灌溉，则会堵塞土壤空隙，妨碍农作物生长。平板陶瓷膜含油废水处理系统作为新型高效含油废水处理技术已经得到各界使用者的认可和赞许，为含油废水的高效处理提供了经济实用的选择。Oily wastewater refers to wastewater containing more oil pollutants and other pollution factors such as inorganic salts. The main oil pollutants are a certain amount of petroleum or animal and vegetable oils, which mainly come from petroleum, petrochemical , Iron and steel, coking, gas generation stations, mechanical processing and other industrial sectors. Among them, oil substances usually exist in four states in wastewater. (1) Floating oil, the particle size of oil droplets is greater than 100μm, which is easy to separate from wastewater. In petroleum sewage, this oil accounts for 60-80% of the total oil content in water. (2) Dispersed oil. The particle size of oil droplets is between 10 and 100 μm, suspended in water. (3) Emulsified oil, the particle size of oil droplets is less than 10 μm, the particle size of oil dispersed in wastewater is very small, it is in an emulsified state, and it is not easy to separate from wastewater. (4) Dissolved oil, the state in which oil is dissolved in water. At present, the treatment of oily wastewater is mostly carried out by traditional methods such as air flotation, gravity separation, and centrifugal separation. Because oily substances exist in various forms in water, the efficiency of traditional methods for treating wastewater containing wastewater is very limited, and it is difficult to achieve Standards for various discharge or water reuse requirements. If the oily wastewater is discharged directly into rivers, lakes or bays without recycling, it will pollute the water body and affect the survival of aquatic organisms; if it is used for agricultural irrigation, it will block the soil voids and hinder the growth of crops. As a new high-efficiency oily wastewater treatment technology, the flat ceramic membrane oily wastewater treatment system has been recognized and praised by users from all walks of life, providing an economical and practical choice for the efficient treatment of oily wastewater.
