技术领域Technical field
本实用新型涉及一种废水处理实验装置,尤其涉及一种一体式部分回流加压溶气气浮实验装置。The utility model relates to a wastewater treatment experimental device, in particular to an integrated partial reflux pressurized dissolved air flotation experimental device.
背景技术Background technique
气浮法是一种有效的固-液和液-液分离方法,常用于对那些颗粒密度接近或小于水的细小颗粒的分离。气浮法处理技术是在水中形成微小气泡形式,使微小气泡与水中悬浮的颗粒吸附,形成水-气-颗粒三相混合体系,颗粒粘附上气泡后,形成表观密度小于水的漂浮絮体,絮体上浮至水面,形成浮渣层被刮除,以此实现固液分离。在废水处理工程中,气浮法处理技术已广泛应用于石油、化工及机械制造业中的含油废水的油水分离、造纸废水中的纸浆纤维及填料的回收、含悬浮固体相对密度接近1的工业废水的预处理等等。Air flotation is an effective solid-liquid and liquid-liquid separation method, often used for the separation of fine particles whose particle density is close to or smaller than water. The air flotation treatment technology forms tiny bubbles in the water, which adsorb the tiny bubbles to the particles suspended in the water to form a water-air-particle three-phase mixed system. After the particles adhere to the bubbles, they form floating floccules with an apparent density smaller than that of water. The floc floats to the water surface and forms a scum layer that is scraped off to achieve solid-liquid separation. In wastewater treatment projects, air flotation treatment technology has been widely used in the oil-water separation of oily wastewater in petroleum, chemical and machinery manufacturing industries, the recovery of pulp fibers and fillers in papermaking wastewater, and industries containing suspended solids with a relative density close to 1. Pretreatment of wastewater, etc.
在各类气浮技术中,加压溶气气浮法是目前常用的气浮处理方法,该法是使空气在加压的条件下溶解于水,然后通过将压力释放至常压从而使过饱和溶解的空气以细微气泡形式释放出来。加压溶气气浮法根据加压溶气水的来源不同可分为全加压溶气流程、部分加压溶气流程和部分回流加压溶气流程,其中部分回流加压溶气流程的加压溶气水为经过气浮处理的澄清水,对溶气及减压释放过程较为有利,是目前最常用的气浮处理流程。目前现有的部分回流加压溶气气浮实验装置设备结构不够完善、成套化、一体化程度不高,影响实验效果、不方便使用者操作。因此,开发一种成套化、一体式部分回流加压溶气气浮实验装置对小型教学及科研实验操作具有重要的意义。Among various types of air flotation technology, pressurized dissolved air flotation is currently a commonly used air flotation treatment method. This method makes air dissolve in water under pressurized conditions, and then releases the pressure to normal pressure to make the process Saturated dissolved air is released in the form of fine bubbles. The pressurized dissolved air flotation method can be divided into full pressurized dissolved air process, partial pressurized dissolved air process and partial reflux pressurized dissolved air process according to the different sources of pressurized dissolved air water. Among them, the partial reflux pressurized dissolved air process is Pressurized air-dissolved water is clarified water that has undergone air flotation treatment, which is more beneficial to the dissolved air and decompression release processes. It is currently the most commonly used air flotation treatment process. At present, the existing partial reflux pressurized dissolved air flotation experimental device has insufficient equipment structure, complete sets, and low degree of integration, which affects the experimental results and is inconvenient for users to operate. Therefore, the development of a complete, integrated partial reflux pressurized dissolved air flotation experimental device is of great significance to small-scale teaching and scientific research experimental operations.
