Description

一种连续流砂过滤器A continuous flow sand filter

技术领域technical field

本实用新型涉及一种污水处理领域,具体涉及一种流砂过滤器。The utility model relates to the field of sewage treatment, in particular to a quicksand filter.

背景技术Background technique

近年来,由于国内水体污染日益严重,中国政府制定了越来越严格的污水排放及回用要求,许多污水处理厂都面临着从一级B到一级A的提标改造,在这个过程中,各种工艺、技术竞相使用。活性砂过滤工艺及技术以其一次性投资费用较低、无需配备反冲洗系统、运行及维护费用低等优势,在市政污水深度处理工艺中占有越来越重要的地位。In recent years, due to the increasingly serious pollution of domestic water bodies, the Chinese government has formulated increasingly stringent requirements for sewage discharge and reuse. Many sewage treatment plants are facing upgrading from Grade B to Grade A. During this process , various crafts and technologies are competing to use. Active sand filtration process and technology occupy an increasingly important position in the municipal sewage advanced treatment process due to its advantages of low one-time investment cost, no need for backwashing system, and low operation and maintenance costs.

另外,随着太湖流域“蓝藻”事件的爆发,政府和各界人士已经越来越意识到氮、磷污染对自然水体的危害,在各项措施中,对现有市政污水处理厂出水“提标改造”已经成为越来越迫切的任务。由于部分污水处理设施在硝化反硝化工艺上的缺失或者运行不稳定可靠,最终生化出水的氨氮或总氮依旧维持在高位水平。In addition, with the outbreak of "cyanobacteria" incidents in the Taihu Lake Basin, the government and people from all walks of life have become more and more aware of the harm of nitrogen and phosphorus pollution to natural water bodies. Transformation" has become an increasingly urgent task. Due to the lack of nitrification and denitrification process in some sewage treatment facilities or unstable and reliable operation, the ammonia nitrogen or total nitrogen in the final biochemical effluent is still maintained at a high level.

带有硝化和反硝化功能的连续流砂过滤器是“提标改造”,进一步去除氨氮或总氮的最佳解决方案;而依靠絮凝反应和本身的物化分离功能,连续流砂过滤器也可以将废水中的磷去除到很低的水平。这些脱氮除磷的功效使得连续流砂过滤器在市政废水“提标改造”中被广泛使用。同时,在整个脱氮除磷过程中,连续流砂过滤器本身强大的自清洗过滤作用可以使得出水悬浮物和浊度获得一个很低的水平。The continuous flow sand filter with nitrification and denitrification functions is the best solution for "standard improvement" to further remove ammonia nitrogen or total nitrogen; and relying on flocculation reaction and its own physical and chemical separation function, continuous flow sand filter can also treat wastewater Phosphorus is removed to a very low level. The effectiveness of these denitrification and phosphorus removal makes the continuous flow sand filter widely used in the "standard improvement" of municipal wastewater. At the same time, during the whole denitrification and phosphorus removal process, the strong self-cleaning and filtering effect of the continuous quicksand filter itself can make the suspended matter and turbidity of the effluent obtain a very low level.

然而,现有流砂过滤器存在的一个主要缺陷是成本高,其主要原因是大部分构件都是一体式结构,损坏之后需要整体更换,导致维修成本高。比如说:洗砂器的主要由内螺旋管和外螺旋管组成,在长期使用中,内螺旋管和外螺旋管易磨损,导致处理效果不好,而维修时需要整个更换内螺旋管和外螺旋管,导致维修费用大。However, a major defect of the existing quicksand filter is high cost. The main reason is that most of the components are integral structures, which need to be replaced as a whole after damage, resulting in high maintenance costs. For example: the sand washing machine is mainly composed of inner helical tube and outer helical tube. In long-term use, the inner helical tube and outer helical tube are easy to wear, resulting in poor treatment effect, and the whole inner helical tube and outer helical tube need to be replaced during maintenance. Spiral pipe, resulting in high maintenance costs.

另外,现有洗沙器的螺旋通道洗砂效果差,导致需要去除的悬浮物随流动的砂重复回到系统之内,影响出水效果。In addition, the sand washing effect of the spiral channel of the existing sand washing device is poor, causing the suspended solids to be removed to return to the system repeatedly with the flowing sand, affecting the water discharge effect.

The outer wall of the inner casing 9-2 and the outer casing 9-3 are connected by a central plate 9-6, and the central plate 9-6 is provided with a water outlet seam 9-7, and the opening at the end of the water inlet main pipe 3 is set at In the water collection container 9-5 at the top of the sand washer 9, the upper end of the water collection container 9-5 is connected with the clean water outlet pipe 10, and the lower end is connected with the sewage discharge pipe 11. The air lift pump 7 is arranged in the bottom cone bucket 5, and the bottom The cone bucket 5 is fixed in the casing 1, and a sand guide bucket 12 is arranged between the bottom cone bucket 5 and the water distributor 4.

所述中心管8和其下端连有空气提升泵7以及洗砂器的内套管9-2可以在不拆卸其他构件前提下方便提出。The central pipe 8 and the inner casing 9-2 connected with the air lift pump 7 and the sand washer at its lower end can be conveniently raised without dismantling other components.

洗砂器9包括内套管9-2、外套管9-3和凸起9-4,凸起9-4呈螺旋状设置,当滤砂下降经过凸起的曲径时,滤砂被迫做涡流运动,同时遇到上升的滤液流,滤砂中的杂质将被冲洗干净,并且随上升的清洗水流出。The sand washer 9 includes an inner sleeve 9-2, an outer sleeve 9-3 and a protrusion 9-4. The protrusion 9-4 is arranged in a spiral shape. When the filter sand descends through the labyrinth of the protrusion, the filter sand is forced to Do vortex movement, and at the same time meet the rising filtrate flow, the impurities in the filter sand will be washed away, and flow out with the rising cleaning water.

本实用新型使用时,过滤器内放置有滤砂料,其主要使用原理如下,1.原水过滤:原水经过进水主管3进入过滤器内部,通过布水器4均匀的向上喷出,水向上逆流通过滤料层,使得水中的污染物含量降低;同时石英砂滤料中污染物的含量增加,下层滤料层的污染物含量高于上层滤料。滤后水依靠重力自流从净水出水管10排出。2.滤料清洗:过滤器底部的滤砂依靠空气提升泵7的提升到达位于过滤器顶部的洗砂器9,通过紊流作用使脏颗粒从活性砂中分离出来,杂质排出,清洗后的滤砂回落到砂床上层,砂子的循环在中心管8内进行。When the utility model is used, filter sand material is placed in the filter, and its main operating principles are as follows: 1. Raw water filtration: raw water enters the filter through the water inlet main pipe 3, and is evenly sprayed upwards through the water distributor 4, and the water is upwards. The reverse flow filter material layer reduces the pollutant content in the water; at the same time, the pollutant content in the quartz sand filter material increases, and the pollutant content of the lower filter material layer is higher than that of the upper filter material. The filtered water is discharged from the clean water outlet pipe 10 by gravity flow. 2. Filter material cleaning: the filter sand at the bottom of the filter is lifted by the air lift pump 7 to the sand washer 9 at the top of the filter, and the dirty particles are separated from the active sand by turbulent flow, and the impurities are discharged. The filter sand falls back to the upper layer of the sand bed, and the circulation of the sand is carried out in the center pipe 8 .

由于石英砂滤料在过滤器中呈自上而下的运动状态,对原水起搅拌作用,因此搅拌絮凝作用可在过滤器内完成。过滤器内滤料清洁及时,可承受较高的进水污染物浓度。当混合物离开空气提升泵的出口时,速率下降,滤砂将落入洗砂器。滤砂的杂质将随洗砂水从清洗水排水管排出。吸入空气提升泵的滤砂量通过控制空气流量控制。较大的气流将提升起更多的滤砂,反之亦然。Since the quartz sand filter material is in a top-to-bottom motion state in the filter, it agitates the raw water, so the agitation and flocculation can be completed in the filter. The filter material in the filter is cleaned in time and can withstand high concentration of pollutants in the water. When the mixture leaves the outlet of the air lift pump, the velocity drops and the filter sand will fall into the sand washer. The impurities in the filter sand will be discharged from the washing water drain along with the sand washing water. The amount of filter sand sucked into the air lift pump is controlled by controlling the air flow. Greater airflow will lift more filter sand and vice versa.

作为优选,所述导砂斗12下端设有四个支撑装置6,支撑装置6包括横截面为三角形的支撑架13,支撑架13上设有U型支撑件14,U型支撑件14与导砂斗12下沿通过螺栓相连,支撑架13一面与底部锥斗5内壁接触。支撑装置6可以比较好的固定导砂斗12,且当导砂斗12或者固定装置6出现故障的时候,比较容易检修,可以更换其中的任何一个部件,减少维修成本。As preferably, the lower end of the sand guide bucket 12 is provided with four support devices 6, the support device 6 includes a support frame 13 with a triangular cross section, and a U-shaped support 14 is arranged on the support frame 13, and the U-shaped support 14 is connected with the guide. The lower edge of the sand bucket 12 is connected by bolts, and one side of the support frame 13 is in contact with the inner wall of the bottom cone bucket 5 . The support device 6 can better fix the sand guide bucket 12, and when the sand guide bucket 12 or the fixing device 6 fails, it is easier to overhaul and any part can be replaced, reducing the maintenance cost.

所述凸起9-4是横截面为三角形的固定板,凸起9-4通过螺栓连接的形式固定在内套管9-2、外套管9-3上,由于长期使用过程中,滤砂上下移动,容易磨损凸起,本实用新型将凸起与内套管9-2、外套管9-3分开采取活动连接的形式设计,比较便于洗砂器的维修,减少维修成本。The protrusion 9-4 is a fixed plate with a triangular cross section, and the protrusion 9-4 is fixed on the inner casing 9-2 and the outer casing 9-3 through bolt connection. Moving up and down, it is easy to wear and tear the protrusions. The utility model separates the protrusions from the inner casing 9-2 and the outer casing 9-3 and adopts a movable connection design, which is more convenient for the maintenance of the sand washer and reduces the maintenance cost.

所述外壳1上设有上下两个视镜16,外壳1上还设有人孔15。通过视镜16可以及时观察过滤器内部情况,通过人孔15可以方便的对装置进行检修。The casing 1 is provided with upper and lower viewing mirrors 16 , and the casing 1 is also provided with a manhole 15 .

如图5所示,优选的,所述布水器4上设有八个布水支管4-1,八个布水支管4-1均布在进水主管3上。这种设置方式使得布水更加均匀,有利于提高除污效果。As shown in FIG. 5 , preferably, the water distributor 4 is provided with eight water distribution branch pipes 4 - 1 , and the eight water distribution branch pipes 4 - 1 are evenly distributed on the water inlet main pipe 3 . This setting method makes the water distribution more uniform, which is conducive to improving the decontamination effect.

作为再一步优选,所述集水外壳9-1固定在调节板17上,调节板17与锁紧旋钮相连。清洗水流由过滤器内滤出液的液位和液位控制容器之间的液位差产生。由液位差产生的压差将推动一小部分滤液。As a further preference, the water collecting shell 9-1 is fixed on the adjusting plate 17, and the adjusting plate 17 is connected with the locking knob. The wash water flow is generated by the level difference between the filtrate level in the filter and the level control vessel. The pressure difference created by the head difference will push a small portion of the filtrate.

如图3所示,所述底部锥斗5由八个等腰的梯形板18组成,梯形板18下端设置在外壳1底部,梯形板18上方设置在梯形板内壁上。这种设计方式便于底部锥斗5的组装、维修。As shown in FIG. 3 , the bottom cone bucket 5 is composed of eight isosceles trapezoidal plates 18 , the lower end of the trapezoidal plates 18 is arranged at the bottom of the shell 1 , and the top of the trapezoidal plates 18 is arranged on the inner wall of the trapezoidal plates.
