技术领域technical field

本实用新型属于污水处理技术领域,具体涉及一种污水处理与再循环利用系统。The utility model belongs to the technical field of sewage treatment, in particular to a sewage treatment and recycling system.

背景技术Background technique

根据统计,我国的江河湖泊和水库中,已经受污染的约占82.3%,全国有监测系统的1200条河流中,已有850条受到污染。据全国2222监测站的监测结果显示,我国七大水系符合《地面水环境质量标准》Ⅰ、Ⅱ类仅占33.2%,符合Ⅲ类标准的占28.9%,属于Ⅳ、Ⅴ类标准的占38.9%。在统计的138个城市河段有133个河段受到不同程度的污染,占统计总数的96。4%,属于超Ⅴ类水质的有53个河段占38%,属Ⅴ类水的27个河段占20%,属Ⅳ类水的26个河段占20%,Ⅱ、Ⅲ类水仅占23%。According to statistics, about 82.3% of the rivers, lakes and reservoirs in our country have been polluted, and 850 of the 1,200 rivers with monitoring systems in the country have been polluted. According to the monitoring results of 2222 monitoring stations across the country, only 33.2% of my country's seven major water systems meet Class I and Class II of the "Surface Water Environmental Quality Standards", 28.9% meet Class III standards, and 38.9% meet Class IV and V standards. . Among the 138 river sections in 138 cities, 133 river sections were polluted to varying degrees, accounting for 96.4% of the total. 53 river sections belonged to Grade V water quality, accounting for 38%, and 27 river sections belonged to Grade V water quality. River sections accounted for 20%, 26 river sections with Class IV water accounted for 20%, and Class II and III water accounted for only 23%.

污水处理既可解决水源的严重污染,又可开发新水源,应该说这是一项事半功倍的事业。所以面对生活污水上升的趋势,我们可以采用家庭污水处理的方法达到减少大量污水排入江河,水资源再次利用的目的。但现在还没有很好的家庭污水处理装置,现有的家庭污水装置,价格昂贵,结构复杂,体积较大,处理效果也不佳,无法满足大多数家庭的要求,导致大量污水流入江河,破坏生态系统。Sewage treatment can not only solve the serious pollution of water sources, but also develop new water sources. It should be said that this is a cause with twice the result with half the effort. Therefore, in the face of the rising trend of domestic sewage, we can use household sewage treatment methods to reduce the discharge of large amounts of sewage into rivers and reuse water resources. However, there is no good domestic sewage treatment device at present. The existing domestic sewage device is expensive, complex in structure, large in size, and poor in treatment effect, which cannot meet the requirements of most families, causing a large amount of sewage to flow into rivers, destroying ecosystem.

生物接触氧化法是一种介于活性污泥法与生物滤池之间的生物膜法工艺,其特点是在池内设置填料,池底曝气对污水进行充氧,经曝气的废水流经填料层,并使池体内污水处于流动状态,以保证污水与污水中的填料充分接触,使填料颗粒表面长满细菌膜,废水和生物膜相接触,在生物膜生物的作用下,废水得到净化。The biological contact oxidation method is a biofilm process between the activated sludge method and the biological filter tank. It is characterized in that fillers are set in the tank, the bottom of the tank is aerated to oxygenate the sewage, and the aerated wastewater flows through Filling layer, and keep the sewage in the pool in a flowing state to ensure full contact between the sewage and the filler in the sewage, so that the surface of the filler particles is covered with a bacterial film, and the wastewater and the biofilm are in contact. Under the action of the biofilm, the wastewater is purified. .

生物接触氧化池内的生物膜由菌胶团、丝状菌、真菌、原生动物和后生动物组成。在生物接触氧化池中,丝状菌在填料空隙间呈立体结构,大大增加了生物相与废水的接触表面,同时因为丝状菌对多数有机物具有较强的氧化能力,对水质负荷变化有较大的适应性,所以是提高净化能力的有力因素。The biofilm in the biological contact oxidation tank is composed of mycelium, filamentous bacteria, fungi, protozoa and metazoa. In the biological contact oxidation tank, the filamentous bacteria have a three-dimensional structure in the gap between the fillers, which greatly increases the contact surface between the biological phase and the wastewater. At the same time, because the filamentous bacteria have a strong oxidation ability to most organic matter, they have a relatively small impact on the change of water quality load. It has great adaptability, so it is a powerful factor to improve the purification ability.

由于生物接触氧化池内生物固体量多,水流完全混合,故对水质水量的骤变有较强的适应能力;剩余污泥量少,不存在污泥膨胀问题,运行管理简便。Due to the large amount of biological solids in the biological contact oxidation tank and the complete mixing of water flow, it has a strong adaptability to sudden changes in water quality and quantity; the amount of residual sludge is small, there is no problem of sludge bulking, and the operation and management are simple.

本实用新型的有益效果:污水通过本污水处理与再循环利用系统净化后,去除率达百分之八十以上,有力的去除了污水中的有害物质,从而达到国家污水排放标准,该系统占用的体积较小,有利于家庭或宿舍内使用,缓解了城市污水处理池的压力,减少成本,更加实用,可以在每家每户普及,同时降低了对水资源的破坏。生物接触氧化具有多种净化功能,它除能够有效地去除有机污染物质外,还能够用以脱氮和磷,并且对冲击负荷有较强的适应能力,污泥生成量少,不产生污泥膨胀的危害,能够保证出水水质,勿需污泥回流,易于维护管理,不产生滤池蝇,也不散发臭气,本装置可用于家庭污水处理。Beneficial effects of the utility model: after the sewage is purified by the sewage treatment and recycling system, the removal rate reaches more than 80%, and the harmful substances in the sewage are effectively removed, thereby reaching the national sewage discharge standard. Its small size is beneficial to use in families or dormitories, relieves the pressure of urban sewage treatment pools, reduces costs, and is more practical. It can be popularized in every household and at the same time reduces the damage to water resources. Biological contact oxidation has a variety of purification functions. In addition to effectively removing organic pollutants, it can also be used to remove nitrogen and phosphorus, and has a strong adaptability to impact loads. The amount of sludge generated is small and no sludge is generated.
