Definitions
- the utility model belongs to the field of water treatment equipment, in particular to an integrated device for an air flotation filter.
- Traditional water treatment processes include air flotation and filtration processes. Sewage contains a large amount of oil, including slick oil, dispersed oil, emulsified oil, and dissolved oil.
- the air flotation process is to dissolve air into water under a certain pressure in advance to form a supersaturated air-water mixture, and then pass through the release device to reduce the oil. After the pressure is released, the air originally dissolved in the water forms a large number of microbubbles. These microbubbles combine with the fine oil and suspended solid particles in the sewage after coagulation and flocculation.
- the overall density decreases, and the particles slowly float up to Scum is formed on the surface of the water, and finally it is scraped away and discharged by the scraping system to realize oil-water separation, which greatly reduces the oil content and suspended solids concentration in the treated water, and has a good removal effect on slick oil, dispersed oil and emulsified oil; filtration
- the process is to use fine particle filter material to accumulate into a filter layer of a certain height. Because there are small gaps between the fine particles, the water can be discharged through the filter layer, and the particles in the water are trapped in the filter layer because it is difficult to pass through the small gaps. At the same time The retained fine particles also have a certain auxiliary effect on filtration.
- the first is to install the air flotation and filtration separately.
- the air flotation device is first and the filter device is second.
- the treatment effect can meet the water treatment requirements, but it occupies a large area, the basic structure is large, and the construction cost is high.
- Water treatment It needs multiple water distributions and has high requirements for elevation and energy consumption; the second type is to combine the air flotation flotation tank vertically on the filter tank to form an air flotation filter.
- the upper part of the filter tank is selected to remove oil and suspended solids, and the water in the lower part of the flotation filter tank passes through the filter plate directly below to filter out residual fine particles.
- the final filtered effluent has less suspended solids, low turbidity and good water quality.
- the combined air flotation filter has the following problems in design and operation:
- the flocculation tank adopts the method of upper water inlet and upper water outlet, and hydraulic short flow often occurs, and the flocculation effect becomes poor, which in turn affects the treatment effect of the air flotation filter;
- the dissolved air releaser generally adopts a fixed opening form, and the releaser is often blocked by particles entrained in the reflux water, but the releaser is located underwater and cannot be repaired in time, resulting in low efficiency of dissolved air release and poor air flotation effect Up to standard;

Abstract
一种气浮滤池一体化装置，所述装置包括：至少一个快混池（2）、至少一对配水池（4）、至少一对絮凝池（8）、至少一对浮选过滤池（13）和至少一个浮渣池（26），所述一体化装置同时实现气浮和过滤工艺，在保证水处理效果的前提下，提高溶气释放效果，延长反洗周期，减轻维修难度，降低设备的运维成本，提高设备的运行稳定性。
Description
本实用新型属于水处理设备领域，具体涉及一种气浮滤池一体化装置。
传统的水处理工艺中，包括气浮和过滤工艺。污水中含有大量油类，包括浮油、分散油、乳化油和溶解油等，气浮工艺是预先将空气在一定压力下溶解到水中，形成过饱和的气水混合物，之后经过释放器的减压释放后，原先溶解在水中的空气形成大量的微气泡，这些微气泡与经过混凝、絮凝后的污水中细小的油类和悬浮物颗粒结合，由于结合后整体密度降低，颗粒物缓慢上浮到水面表面形成浮渣，最后再通过刮渣***刮走排出，实现油水分离，大大降低处理后水中的含油量和悬浮物浓度，对浮油、分散油和乳化油具有很好的去除效果；过滤工艺是采用细颗粒的滤料堆积成一定高度的过滤层，由于细颗粒之间有细小空隙，因此水能够通过过滤层排出，而水中的颗粒物由于难以通过细小缝隙，被截留到滤层，同时截留的细颗粒对过滤也有一定的辅助作用。随着过滤的进行，原先干净的滤层缝隙里被水中的细颗粒逐渐填充，一定周期后滤层的过水阻力增大，逐渐丧失过滤净化作用，此时，需要采用水反洗和气反洗，将滤层拦截的细颗粒反向冲刷，从滤层分理排出，使滤层恢复过滤拦截功能。
在水处理中实现气浮和过滤工艺有两种方式。第一种，将气浮和过滤分开设置，通常气浮装置在先，过滤装置在后，处理效果上能满足水处理要求，但是占地面积大、基础构筑物体积大且建设成本高、水处理时需多次配水且对高程及能耗要求高；第二种，将气浮的浮选池纵向叠合在过滤池之上组合为气浮滤池，进水先经快混、絮凝后，在浮选过滤池上部去除油类和悬浮物，浮选过滤池下部的水再通过正下方的过滤板滤除残余的细小颗粒物，最终过滤后的出水悬浮物含量少、浊度低、水质好。
现有技术中，组合式的气浮滤池在设计和运行时存在以下问题：
1）、在快混池之后进行配水时，将溢流配水管安装在絮凝池内部，溢流配水管上的控制阀门位于水下，阀门需要定制，且长期浸泡于水下，腐蚀严重、故障率高、且难以检修；
2）、絮凝池采用上进水、上出水的方式，经常出现水力短流，絮凝效果变差，进而影响气浮滤池的处理效果；
3）、溶气释放器一般采用固定开度形式，经常出现释放器被回流水中夹带的颗粒物堵塞的情形，但释放器位于水下，无法及时检修，造成溶气释放效率低下，气浮效果不达标；
4）、浮选过滤池的底部滤板采用现场浇筑，很难控制过滤区的滤板平整度，进而影响过滤区域的水流均匀分布，容易出现沟流和滤料截污分布不均，造成水质穿透加快，出水水质快速恶化，反洗周期短。
鉴于现有技术中存在的上述问题，本实用新型提供了一种气浮滤池一体化装置，将气浮池和过滤池组合，同时实现气浮和过滤工艺，在保证水处理效果的前提下，提高溶气释放效果，延长反洗周期，减轻维修难度，降低设备的运维成本，提高设备的运行稳定性。
