Description
技术领域 technical field
本实用新型涉及污水处理设备领域，特别涉及一种地埋式无动力五格净化槽污水处理设备。 The utility model relates to the field of sewage treatment equipment, in particular to a sewage treatment equipment of an underground non-powered five-grid purification tank.
背景技术 Background technique
目前，我国农村对生活污水的处理多利用化粪池预处理，然后采用微生物处理技术的方式。化粪池的主要作用为消解粪便，另外还有一定的沉淀杂物作用。微生物处理技术是利用微生物的新陈代谢除去污水中的有机污染物。这种处理方式存在一定的缺陷。首先，化粪池只能做为粪便污水的预处理，其处理后的出水有机物浓度较高，仅能满足下水道水质标准。农村地区没有污水处理厂的情况下，其出水不经二级处理和三级处理，将会对周围水环境造成污染。 At present, the treatment of domestic sewage in rural areas of our country mostly uses septic tank pretreatment, and then adopts the method of microbial treatment technology. The main function of the septic tank is to digest the feces, and it also has a certain role of sedimentation. Microbial treatment technology is to use the metabolism of microorganisms to remove organic pollutants in sewage. There are certain flaws in this approach. First of all, septic tanks can only be used as pretreatment of fecal sewage, and the concentration of organic matter in the treated effluent is relatively high, which can only meet the sewer water quality standards. In the absence of sewage treatment plants in rural areas, the effluent will pollute the surrounding water environment without secondary and tertiary treatment.
其次，后续的二级处理和三级处理装置若采用钢筋混凝土结构，由于内部结构复杂、构筑物尺寸较小，施工难度较大。在施工经不足和管理不到位的情况下，容易导致结构漏水和进出水标高不准确，严重影响设施的运行效果。再次，采用分开设置的化粪池和后续处理设施，不仅增加占地面积和连接管网，而且运行管理维护工作量较大，增加了工程费用和维护费用。 Secondly, if the subsequent secondary treatment and tertiary treatment devices adopt reinforced concrete structures, due to the complex internal structure and small size of the structures, the construction will be more difficult. In the case of insufficient construction experience and inadequate management, it is easy to cause water leakage in the structure and inaccurate elevations of water in and out, which seriously affects the operation effect of the facility. Thirdly, the use of separate septic tanks and subsequent treatment facilities not only increases the floor area and connects the pipe network, but also increases the workload of operation, management and maintenance, which increases the engineering cost and maintenance cost.
由此，有必要针对农村等特定环境，提高污水处理，特别是生活污水处理设备的小型化，并在此基础上提高污水处理能力。 Therefore, it is necessary to improve sewage treatment for specific environments such as rural areas, especially the miniaturization of domestic sewage treatment equipment, and improve sewage treatment capacity on this basis.

具体实施方式 Detailed ways
下面结合实施例对本实用新型作进一步的详细描述。 Below in conjunction with embodiment the utility model is described in further detail.
实施例1 Example 1
一种地埋式无动力五格净化槽污水处理设备，如图1-3所示，该设备被设计用于处理生活污水，尤其是粪便等污水，包括一个用于作为生活污水处理容纳空间的罐体100以及设置于所述罐体100上的进水管101和出水管102。罐体100可以采用任何现有的具有足够强度的材料制成，例如复合材料，其内部的下述的其他结构可以使用PVC或者类似的材料制得。罐体100为圆柱体结构，或 者其他类似的扁圆柱体结构。 An underground non-powered five-grid purification tank sewage treatment equipment, as shown in Figure 1-3, the equipment is designed to treat domestic sewage, especially feces and other sewage, including a storage space for domestic sewage treatment The tank body 100 and the water inlet pipe 101 and the water outlet pipe 102 arranged on the tank body 100 . The tank body 100 can be made of any existing material with sufficient strength, such as a composite material, and other internal structures described below can be made of PVC or similar materials. The tank body 100 is a cylindrical structure, or other similar oblate cylindrical structures.
所述罐体100内部被分隔为沿着污水的流动方向排列且依次连通的发酵池200、厌氧池300以及沉淀消毒池400；进一步地，作为一种可选的方案，可以在发酵池200与进水管101之间设置一个前置发酵池200a作为一级发酵池使用，形成多级发酵池200，可以在厌氧池300与发酵池200之间连通一个前置厌氧池300a作为一级厌氧池300使用，形成多级厌氧池300。多级的厌氧池300以及多级的发酵池200提高了罐体100内的有效容积，并且减少了污水在每个池子内的停留时间，有利于提高污水的流动性。发酵池200、厌氧池300以及沉淀消毒池400之间通过管道连通，尤其是，发酵池200与发酵池200之间，厌氧池300与沉淀消毒池400之间的连通管道均设置有垂直段，具体而言，如图所示，进水管101的出水端，一级发酵池200与二级发酵池200之间的连通管道的进水端，二级发酵池200与一级厌氧池300之间的连通管道的进水端均设置有垂直段。需要指出的是，本实施例所记载的五格净化槽是为了处理生活污水包括洗涤用水、餐厨用水及卫浴用水等污水进行特别设计的。包括在三格式化粪池的基础上，增加了二级发酵池200与二级厌氧池300并组成本实施例所记载的五格净化槽，此外，经使用发现，单一一个发酵池200和厌氧池300与两格式的发酵池200、厌氧池300在净化效率和处理量等几个方面存在较大的差别，与单一发酵池200和厌氧池300相比，本实施例所记载的两格式的发酵池200和厌氧池300在污水处理量上提高了约55％，处理后的污水中悬浮物的含量下降了大约23％，化学需氧量下降了30％。此外，使用本实施例所记载的五格净化槽尤其适用于处理生活污水，相比而言，只有单一发酵池200和厌氧池300的净化槽在处理粪便等生活污水显得尤为不力，经常会出现发酵池和厌氧池堵塞的问题，且由于污水在发酵池200和厌氧池300内的停留时间过长，容易造成堵塞。 The interior of the tank body 100 is divided into fermentation tanks 200, anaerobic tanks 300, and sedimentation disinfection tanks 400 arranged along the flow direction of sewage and connected in sequence; further, as an optional solution, fermentation tanks 200 can be A pre-fermentation tank 200a is set between the water inlet pipe 101 and used as a primary fermentation tank to form a multi-stage fermentation tank 200, and a pre-anaerobic tank 300a can be connected between the anaerobic tank 300 and the fermentation tank 200 as a primary fermentation tank. The anaerobic tank 300 is used to form a multi-stage anaerobic tank 300 . The multi-stage anaerobic tank 300 and the multi-stage fermentation tank 200 increase the effective volume of the tank body 100 and reduce the residence time of the sewage in each tank, which is beneficial to improve the fluidity of the sewage. The fermentation tank 200, the anaerobic tank 300 and the sedimentation disinfection tank 400 are connected by pipelines, especially, between the fermentation tank 200 and the fermentation tank 200, the communication pipelines between the anaerobic tank 300 and the sedimentation disinfection tank 400 are all provided with vertical section, specifically, as shown in the figure, the water outlet end of the water inlet pipe 101, the water inlet end of the connecting pipeline between the primary fermentation tank 200 and the secondary fermentation tank 200, the secondary fermentation tank 200 and the primary anaerobic tank The water inlet ends of the communication pipes between 300 are all provided with vertical sections. It should be pointed out that the five-compartment purification tank described in this embodiment is specially designed to treat domestic sewage, including washing water, kitchen water and bathroom water. Including on the basis of the three-format septic tank, the secondary fermentation tank 200 and the secondary anaerobic tank 300 are added to form the five-grid purification tank described in this embodiment. In addition, it is found through use that a single fermentation tank 200 and The anaerobic tank 300 is different from the two-format fermentation tank 200 and anaerobic tank 300 in several aspects such as purification efficiency and processing capacity. Compared with the single fermentation tank 200 and the anaerobic tank 300, the present embodiment records The two formats of the fermentation tank 200 and the anaerobic tank 300 increase the sewage treatment capacity by about 55%, the content of suspended solids in the treated sewage decreases by about 23%, and the chemical oxygen demand decreases by 30%. In addition, the use of the five-grid septic tank described in this embodiment is especially suitable for treating domestic sewage. In comparison, the septic tank with only a single fermentation tank 200 and anaerobic tank 300 is particularly ineffective in treating domestic sewage such as feces, and often The problem of clogging of the fermentation tank and the anaerobic tank occurs, and because the residence time of the sewage in the fermentation tank 200 and the anaerobic tank 300 is too long, it is easy to cause clogging.
所述厌氧池300内设置有由可悬浮性材料组成的悬浮层310；该可悬浮性材料优选为采用多孔隙填料，便于微生物的附着与繁殖。通过厌氧微生物的活动与繁殖能将污水中污染物去除。多孔隙填料至少具有一定的浮力可以依靠自身 悬浮在污水的上层，作为一种可选的方案，可以将这种多孔隙填料通过粘合剂以及适当的包裹材料组成球形或者其他形状的浮球填料，所使用的粘合剂可以是任何的非水溶性的粘合剂，包裹材料选用具有多层结构的材料，例如废弃的多孔多层材料或者植物的坚韧表层部分。需要注意的是，附图1中，悬浮层310显示为弯曲状是为了能够更好地表示悬浮层310与栅格网之间的关系，并非显示悬浮层310的实际形状。 The anaerobic tank 300 is provided with a suspension layer 310 composed of suspendable material; the suspendable material is preferably a porous filler to facilitate the attachment and reproduction of microorganisms. The pollutants in the sewage can be removed through the activity and reproduction of anaerobic microorganisms. The porous packing has at least a certain buoyancy and can rely on itself to suspend in the upper layer of the sewage. As an optional solution, this porous packing can be formed into a spherical or other shaped floating ball packing through a binder and an appropriate wrapping material. The adhesive used can be any water-insoluble adhesive, and the wrapping material is selected from a material with a multi-layer structure, such as discarded porous multi-layer materials or tough surface parts of plants. It should be noted that, in FIG. 1 , the suspension layer 310 is displayed as a curved shape to better represent the relationship between the suspension layer 310 and the grid network, but not to show the actual shape of the suspension layer 310 .
所述悬浮层310被可调节地设置为具有足够的厚度且令所述厌氧池300内的污水经由所述悬浮层310才能够由所述厌氧池300流出。悬浮层310由设置于厌氧池300，包括前置厌氧池300a内的多级厌氧池300内的栅格网组成，上下两层栅格网将悬浮性材料保持在厌氧池300的中部，可以使用栅格网支撑架固定和调节悬浮层的位置，也可以设置浮力设备，令栅格网可以随着水位高低进行调节，特殊之处在于，悬浮层的高度应当位于厌氧池300的出水管处，厌氧池300内的污水只有在流经了悬浮层之后才能由出水管排出。若有多级厌氧池300，其内设的悬浮层310结构是类似的，不同之处在于，后一级厌氧池300的悬浮层310的厚度应当大于前一级厌氧池300内悬浮层310的厚度，且应当通过调整栅格网的高度令不同的厌氧池300内的悬浮层310的底部位于同一高度。进一步地，前一级的厌氧池300内的污水通过溢水口进入后一级的厌氧池300，与发酵池200以及沉淀消毒池400不同的是，厌氧池300内采用溢流式出水，污水沿着厌氧池300的侧壁缓缓流入并沉入厌氧池300底部，并逐渐上升，通过悬浮层310溢出，可选地，可以利用抽水泵将上层清液抽入下一级厌氧池300，但由于罐体100是埋入地底的，考虑到维修便捷性，通常不安装抽水泵，仅仅利用溢流将污水导入下一级的厌氧池300。 The suspension layer 310 is adjustable to have a sufficient thickness so that the sewage in the anaerobic tank 300 can flow out of the anaerobic tank 300 through the suspension layer 310 . Suspension layer 310 is made up of the grid network that is arranged in anaerobic tank 300, including the multi-stage anaerobic tank 300 in pre-anaerobic tank 300a, and the upper and lower layers of grid network keep the suspended material in the anaerobic tank 300 In the middle, the grid support frame can be used to fix and adjust the position of the suspension layer, and buoyancy equipment can also be set so that the grid grid can be adjusted with the water level. The special feature is that the height of the suspension layer should be at the anaerobic pool 300 At the water outlet pipe, the sewage in the anaerobic tank 300 can only be discharged by the water outlet pipe after flowing through the suspension layer. If there are multiple anaerobic tanks 300, the structure of the suspension layer 310 in it is similar, the difference is that the thickness of the suspension layer 310 of the rear anaerobic tank 300 should be greater than that of the suspension layer 300 in the previous anaerobic tank 300. The thickness of the layer 310, and the bottom of the suspension layer 310 in different anaerobic tanks 300 should be at the same height by adjusting the height of the grid. Further, the sewage in the anaerobic pond 300 of the previous stage enters the anaerobic pond 300 of the latter stage through the overflow port. Unlike the fermentation pond 200 and the sedimentation disinfection pond 400, the anaerobic pond 300 adopts an overflow type water outlet , the sewage flows slowly along the side wall of the anaerobic pool 300 and sinks into the bottom of the anaerobic pool 300, and gradually rises and overflows through the suspension layer 310. Optionally, a pump can be used to pump the supernatant into the next stage The anaerobic tank 300, but because the tank body 100 is buried in the ground, considering the convenience of maintenance, a pump is usually not installed, and the sewage is only introduced into the next-level anaerobic tank 300 by overflow.
所述沉淀消毒池400还包括消毒槽410，如图4所示；所述消毒槽410与所述厌氧池300的出水管相连接，用于承接由所述厌氧池300导出的污水；所述消毒槽410的侧壁设置有出水孔411。作为一个优选的方案，消毒槽410为一个三面侧壁均开有出水孔411的正方体或者长方体结构，其内部中空，用于容纳由厌氧池300的出水管导出的污水，该出水管设置有一个垂直段，将污水自上 而下地引导进入消毒槽410。在使用过程中，沉淀消毒池400内的污水通常至少应当没过消毒槽410的顶端，或者其水位应当位于出水管的垂直段处，或者更高。为了能够最大限度地缩短罐体100的长度，需要能够尽可能地提高罐体100的垂直空间的利用率，为此，当厌氧池300的污水由出水管的垂直段进入消毒槽410后，污水首先触及消毒槽410底部，消毒剂或者消毒剂释放装置释放口可以被放置于此，从而达到消毒的效果。污水触及消毒槽410底部后，沿着消毒槽410侧壁上升，由于此时流速较大，因此遇到侧壁的出水孔411则会由出水孔411流出，达到降低流速的目的，减速后的污水继续上升，到达消毒槽410的顶部后，沿着消毒槽410顶部的开口溢出。由出水孔411流出的污水则会沿着水平方向继续前行并逐渐减速直至与沉淀消毒池400内的污水相对静止。由出水孔411流出的污水在沉淀消毒池400的中部形成一个水平的隔绝层，防止上部的污水流动搅动下部的沉淀物。此外，作为另一种可选的方案，消毒槽410的上部开口仅仅与厌氧池300的出水管相连接，污水仅能够由出水孔411流出，形成一个水平的冲刷层，并在冲刷的过程中，通过逐渐减速实现沉淀和分层。进一步地，为了能够进一步降低由出水孔411流入沉淀消毒池400的流速，出水孔411的边缘应当呈圆弧形，例如，可以是圆形或者是扁圆形的出水孔411，有利于分散水流，提高沉淀效果。 The sedimentation disinfection tank 400 also includes a disinfection tank 410, as shown in Figure 4; the disinfection tank 410 is connected with the outlet pipe of the anaerobic tank 300, and is used to receive the sewage derived from the anaerobic tank 300; The side wall of the disinfection tank 410 is provided with a water outlet hole 411 . As a preferred solution, the disinfection tank 410 is a cube or cuboid structure with water outlet holes 411 on three side walls, and its interior is hollow to accommodate the sewage led by the outlet pipe of the anaerobic pool 300. The outlet pipe is provided with A vertical section guides the sewage into the disinfection tank 410 from top to bottom. During use, the sewage in the sedimentation disinfection tank 400 should usually at least submerge the top of the disinfection tank 410, or its water level should be at the vertical section of the outlet pipe, or higher. In order to shorten the length of the tank body 100 to the greatest extent, it is necessary to improve the utilization rate of the vertical space of the tank body 100 as much as possible. The sewage first touches the bottom of the disinfection tank 410, where the disinfectant or the discharge port of the disinfectant release device can be placed, so as to achieve the disinfection effect. After the sewage touches the bottom of the disinfection tank 410, it rises along the side wall of the disinfection tank 410. Since the flow velocity is relatively high at this time, it will flow out of the water outlet hole 411 when it encounters the side wall, so as to reduce the flow velocity. The sewage continues to rise, and after reaching the top of the disinfection tank 410, it overflows along the opening at the top of the disinfection tank 410. The sewage flowing out of the water outlet hole 411 will continue to move forward along the horizontal direction and gradually decelerate until it is relatively still with the sewage in the sedimentation disinfection tank 400 . The sewage flowing out from the water outlet hole 411 forms a horizontal insulating layer in the middle of the sedimentation disinfection tank 400 to prevent the sewage flow in the upper part from stirring the sediment in the lower part. In addition, as another optional solution, the upper opening of the disinfection tank 410 is only connected to the outlet pipe of the anaerobic tank 300, and the sewage can only flow out through the outlet hole 411, forming a horizontal scour layer, and during the scour process In , settling and stratification are achieved by gradual deceleration. Further, in order to further reduce the flow rate from the water outlet hole 411 into the sedimentation disinfection tank 400, the edge of the water outlet hole 411 should be arc-shaped, for example, it can be a circular or oblate water outlet hole 411, which is conducive to dispersing the water flow , improve the precipitation effect.
所述厌氧池300的出水管伸入所述消毒槽410，且该出水管的出水口至少位于所述消毒槽410的中部或者底部，有利于污水与消毒剂的混合，也可以减少污水直接通过消毒槽410的出水孔411流出导致的消毒不彻底和流速过快的问题。 The outlet pipe of the anaerobic tank 300 extends into the disinfection tank 410, and the outlet of the outlet pipe is at least located in the middle or bottom of the disinfection tank 410, which is conducive to the mixing of sewage and disinfectant, and can also reduce the direct discharge of sewage. The problems of incomplete disinfection and excessive flow rate caused by the outflow through the water outlet hole 411 of the disinfection tank 410 .
所述消毒槽410位于所述沉淀消毒池400垂直方向的中部。消毒槽410的一侧侧壁紧贴沉淀消毒池400的侧壁，尽量地位于沉淀消毒池400的一侧，另外三侧开口，污水由消毒槽410的出水孔411出发，由沉淀消毒池400的一侧向其另一侧流淌，能够提高对罐体100内空间的利用效率。 The disinfection tank 410 is located in the middle of the sedimentation disinfection tank 400 in the vertical direction. One side wall of the disinfection tank 410 is close to the side wall of the sedimentation disinfection tank 400, located on one side of the sedimentation disinfection tank 400 as far as possible, and the other three sides are open. One side of the container flows to the other side, which can improve the utilization efficiency of the space in the tank body 100 .
总之，以上所述仅为本实用新型的较佳实施例，凡依本实用新型申请专利范围所作的均等变化与修饰，皆应属本实用新型专利的涵盖范围。 In a word, the above descriptions are only preferred embodiments of the present utility model, and all equal changes and modifications made according to the patent scope of the utility model should fall within the scope of the utility model patent.
