Description
技术领域technical field
本实用新型涉及一种曝气生物滤池，尤其涉及一种中空多孔纤维填料折流曝气生物滤池。The utility model relates to an aerated biological filter, in particular to a hollow porous fiber filler deflection aerated biological filter.
背景技术Background technique
曝气生物滤池是集生物氧化和截留悬浮固体于一体，节省了后续二次沉淀池，在保证处理效果的前提下使处理工艺简化，此外，曝气生物滤池工艺有机物容积负荷高、水力负荷大、水力停留时间短、所需基建投资少、能耗及运行成本低、同时该工艺出水水质高。滤料是曝气生物滤池的关键部分，对曝气生物滤池的功效有直接的影响，同时也影响到曝气生物滤池的结构形式和成本。由于制作加工和价格原因，国内目前采用的接触填料主要有玻璃钢或塑料蜂窝填料、立体波状填料、软性纤维填料、半软性填料以及不规则粒状滤料（砂、碎石、矿渣、焦炭、无烟煤）等。玻璃钢或塑料填料表面光滑，生物膜附着力差，易老化，且在实际使用中往往容易产生不同程度填料的堵塞；软性填料中的水流流态不理想，易被微生物膜粘结在一起，产生结球现象，使其有效表面积大为减小，进而在结球的内部产生厌氧现象，影响处理效果。不规则粒状填料水流阻力大，易于引起滤池堵塞。近年来我国也开展了应用片状陶粒处理水源的微污染研究，片状陶粒属不规则粒状填料，尽管挂膜性能良好，但存在水流阻力大、孔隙率小、容易堵塞、强度差、易破碎、不耐冲刷等缺陷，限制了它仅能应用于水源水的微污染处理，而不适合污水处理。正是由于这些传统的接触填料存在一定的缺陷，限制了曝气生物滤池在我国污水处理中的应用，因此选用一种好的滤池滤料非常关键。The biological aerated filter integrates biological oxidation and interception of suspended solids, saves the subsequent secondary sedimentation tank, and simplifies the treatment process under the premise of ensuring the treatment effect. Large load, short hydraulic retention time, less infrastructure investment required, low energy consumption and operating costs, and high quality effluent from the process. The filter material is a key part of the biological aerated filter, which has a direct impact on the efficacy of the biological aerated filter, and also affects the structure and cost of the biological aerated filter. Due to production, processing and price reasons, the contact fillers currently used in China mainly include glass fiber reinforced plastic or plastic honeycomb fillers, three-dimensional corrugated fillers, soft fiber fillers, semi-soft fillers, and irregular granular filter materials (sand, gravel, slag, coke, anthracite), etc. The surface of FRP or plastic packing is smooth, the adhesion of biofilm is poor, and it is easy to age, and in actual use, it is easy to cause plugging of packing to varying degrees; the flow of water in soft packing is not ideal, and it is easy to be bonded together by microbial film. The phenomenon of balling occurs, which greatly reduces the effective surface area, and then produces anaerobic phenomenon inside the ball, which affects the treatment effect. Irregular granular packing has high resistance to water flow, which is easy to cause filter blockage. In recent years, my country has also carried out micro-pollution research on the application of flaky ceramsite to treat water sources. Flake ceramsite is an irregular granular filler. Although the film-hanging performance is good, it has large water flow resistance, small porosity, easy clogging, poor strength, Defects such as fragility and intolerance to erosion limit it to be used only for micro-pollution treatment of source water, not for sewage treatment. It is precisely because these traditional contact packings have certain defects that limit the application of biological aerated filters in sewage treatment in my country, so it is very important to choose a good filter material.

本实用新型的技术效果是：水流以上下的方式流动，增加水流程和水处理时间，同时垂直于中空纤维膜，利于微生物的截留。此外，中空纤维膜的比表面积特别大，提高了单位空间内的污泥浓度，该发明采用无泡供氧，氧的传质效率也大大提高，能够处理高浓度有机废水。另外，滤料在水中呈流态状，不易堵塞，可减少反冲洗频率，节约能源，减少占地面积。The technical effect of the utility model is: the water flows in an up and down manner, increases the water flow and water treatment time, and at the same time is perpendicular to the hollow fiber membrane, which is beneficial to the interception of microorganisms. In addition, the specific surface area of the hollow fiber membrane is particularly large, which increases the sludge concentration in a unit space. The invention uses non-bubble oxygen supply, and the oxygen mass transfer efficiency is also greatly improved, which can treat high-concentration organic wastewater. In addition, the filter material is in a fluid state in the water and is not easy to be blocked, which can reduce the frequency of backwashing, save energy, and reduce the occupied area.
