- the first annular protrusions 307 then between the first annular protrusions 307 and the second rolling disc 303, and so on, that is, moving to the edge of the second rolling disc 303 through various gaps, and finally from The material port 306 is discharged.
- the treatment method of the sewage treatment device specifically includes the following steps:
- Step 1 The water source to be treated enters the primary filtration unit 1 through the water inlet pipe, and the suspended solids are filtered and discharged inside the primary filtration unit 1: the water to be treated enters directly from the water inlet 102 of the first cylinder 101 into the primary filter unit 1.
- the inside of the separation net 106 at the same time, driven by the drive motor 104, the separation net 106 rotates together with the conveying plate 105, and a water flow is generated to the water source located inside the separation net 106. Under the action of the water flow, the water will With very small particles thrown out of the separation net 106, while the suspended matter with larger particles is still enclosed in the separation net 106;
- step 2 the suspended matter located inside the separation net 106 is transported into the sewage outlet under the action of the rotating conveying plate 105. Considering that the end of the transmission shaft 103 and the conveying plate 105 close to the sewage outlet extends to the outside of the separation net 106, That is, the suspended solids will be accurately transported to the sewage discharge unit 3 connected to the sewage outlet for processing, and step 4 is performed;
- Step 3 The water thrown out to the separation net 106 is smooth under the action of the flow of the plurality of cylinders 108 on the two side walls of the annular ring 107 or under the action of the pressure difference produced by the separation net 106 in the circular truncated structure.
- the water flows to the first water outlet, and is transferred to the secondary filter unit 2 through the connecting pipe, and step 5 is performed;
- Step 4 The separated suspended matter enters the connecting body 301 through the sewage outlet. Because the second rolling disc 303 rotates relative to the first rolling disc 302 under the action of the rotating motor 305, and during the rotation, it is also The second annular protrusion 308 rotates in the slot between the adjacent first annular protrusions 307; the suspended matter is first transferred between the second annular protrusion 308 and the first annular protrusion 307 through the through hole 309, and then Then pass between the first annular protrusion 307 and the second rolling disc 303, and so on, that is, move to the edge of the second rolling disc 303 through various gaps, and finally discharge from the material port 306.
- Step 5 reaching the water in the secondary filtration unit 2, first passes through the water quality filter element 207 in the first cavity, and adsorbs the fine particles that are not processed in the primary filtration unit 1;
- Step 6 then enter the multi-layer filter membrane in the second cavity to carry out adsorption treatment to remove chlorine and microbes in the water;
- the filters used in Steps 5 and 6 are three-dimensional filters with a porous structure and a large specific surface area. , the characteristics of uniform pore size distribution, to achieve high-precision filtration.

使用如上所述的过滤网的污水处理装置的处理方法，具体包括以下步骤：
步骤一、待处理的水源通过进水管进入到一级过滤单元，在一级过滤单元内部实现对悬浮物的过滤并排出：待处理水从第一筒体的进水口直接进入到分离网的内部，同时分离网在所述驱动电机的驱动下，和所述输送板一起发生自转同时会对位于分离网内部的水源产生水流，在水流的作用下，水会带着极小颗粒被甩出到分离网外，而颗粒较大的悬浮物则仍在被圈在分离网内；
步骤二、位于分离网内部的悬浮物在自转的输送板的作用下，被输送到排污口内，考虑到所述传动轴和输送板靠近排污口的一端延伸至分离网外，即悬浮物会准确的被输送到与排污口相连的排污单元内进行处理，执行步骤四；
步骤三、甩出到分离网的水，在环形圈的两侧壁上的多个柱体产生流动的作用下或者在呈圆台结构的分离网产生的压力差的作用下，顺畅的流向第一出水口处，并通过连接管转移到二级过滤单元中去，执行步骤五；
步骤四、被分离出来的悬浮物经排污口进入到连接体内，由于第二碾压盘在转动电机的作用下，相对第一碾压盘转动，且转动的过程中，也是第二环形凸起在相邻的第一环形凸起之间的卡槽内转动；悬浮物首先经过通孔转移到第二环形凸起与第一环形凸起之间，然后再经过第一环形凸起与第二碾压盘之间，依次类推，即通过各种缝隙向第二碾压盘的边缘处移动，最终从物料口排出，当物料从通孔进入到第一碾压盘与第二碾压盘重叠的部分直至排出，整个过程都是受到第一环形凸起和第二环形凸起的碾压作用，将大颗粒变成极小颗粒并排出；
步骤五、达到二级过滤单元中的水，先进过第一容腔内的水质滤芯，对在一级过滤单元中没有处理到的细小颗粒进行吸附；
步骤六、随后进过第二容腔内的多层滤膜进行吸附处理，去除水中的氯、微菌；步骤五和步骤六中使用的滤网为三维滤网，具有多孔结构，比表面积大，孔径大小分布均匀的特点，实现高精度过滤。
本发明的污水处理装置中使用的过滤网为三维编织网，由两种网径不同的网丝编织而成的三维多孔结构，具有孔隙率高、比表面积大、孔径大小分布均匀等特点，解决了现有技术中的过滤不彻底或者因流量小导致的堵塞问题。

下面结合附图说明和具体实施例对本发明做进一步的描述。
发明人发现：现有的水处理过程中，一般是通过过滤网进行多层过滤实现对水的处理，达到高效的过滤效果，或者是由滤网包裹成滤芯进行过滤。但是现有的滤网都是二维网，二维网在交叉编织时网丝与网丝之间的重叠度较大，与水流相互垂直的实际过滤面积相对于计算出来的过滤面积小很多，也就是真正过滤的效果实际是远远低于预期的过滤效果的。
如图1所示，一个过滤网的结构如下，具体包括：第一网丝4和第二网丝5。所述第一网丝4和所述第二网丝5的数量为若干个且相同。为了能够增加过滤网的孔隙率高和比表面积，所述第一网丝和第二网丝的网径不相等，且所述第一网丝与所述第二网丝的编织结构如下：
其中一部分第一网丝4和第二网丝5等距离的交错分布在X轴向上，剩余的第一网丝4和第二网丝5等距离的交错分布在Y轴向上，位于Y轴向上的第一网丝呈正弦依次穿过位于X轴向上的第一网丝和第二网丝，位于Y轴向上的第二网丝呈余弦依次穿过位于X轴向上的第一网丝和第二网丝，具体的可见图2。
如图12所示，设定第一网丝的网径为R1，第二网丝的网径为R2，所述R1和R2之间满足以下关系：
R1＞0.3mm，R2/R1=1.4~2.4；
定义第一网丝处与第二网丝的交叉角为二面角α1，第二网丝处于第一网丝的交叉角为二面角α2，
则，α1=tan^(-1)[(1/2 R2+R1)/d]，α2=tan^(-1)[(1/2
R1+R2)/d]，其中，d为第一网丝与第二网丝之间的距离，且d的取值应当满足α1、α2的取值范围在5-15°之间。
满足上述条件的过滤网中的第一网丝与第二网丝之间的交叉角度在5-15°之间，既能满足强度需求同时还能保证实际水流过滤的面积为最大，过滤的效率是最高。如果第一网丝与第二网丝之间的交叉角度超过15°，则第一网丝与第二网丝之间的贴切度大，弯折度也随之增大，过滤的有效面积变小。同时本发明的过滤网相对有现有技术过滤网而言具备较好的柔性，不同网径之间的交叉构成必不可少的弹性空间，因此本发明的过滤网适合任何形状的叠加，使用范围广。克服了现有技术中的过滤网过硬的问题。
上述过滤网被使用到下文的污水装置中，具体表现为：目前在水处理时，为了能够提高对水处理的力度，增加过滤后的水的清洁度，设置为多级过滤，但是不管是几级过滤，位于第一、二级的过滤单元中的过滤器是需要进行固液分离的，好比淤泥、颗粒等。为此发明人基于上述过滤网，对现有的污水处理装置做了以下改进：
如图3所示，过滤网的污水处理装置，包括：所述一级过滤单元1与进水管直接连通，所述二级过滤单元2通过连接管与所述第一过滤单元的出水口相通，同时所述一级过滤单元1还与排污单元3相连通。所述一级过滤单元1不仅仅是用于固液分离同时还能将分离出来的固体排出到排污单元3，通过排污单元3进行处理和高效排出。
整个系统的工作流程如下：待处理的水源通过进水管进入到一级过滤单元1，通过一级过滤单元1对其进行固液分离，且被分离出来的水通过连接管转移到二级过滤单元2内进行吸附处理，被处理后水质从二级过滤单元2的排水口205排出；在一级过滤单元1中被分离出来的悬浮物经排污单元3排出。
在进一步的实施例中，为了能够将固、液进行有效的分离并将分离出来的固定或者悬浮物输送到指定位置处便于排污单元3处理。如图4和图5所示，所述一级过滤单元1包括：横向放置的第一筒体101，所述第一筒体101的一端开有进水口102。所述第一筒体101靠近所述进水口102的一侧固定安装有驱动电机104，所述驱动电机104的输出轴上传动连接有传动轴103，所述传动轴103沿所述第一筒体101的长度方向设置在所述第一筒体101的内部；所述传动轴103靠近所述进水口102的一端固定有固定圈，所述固定圈位于进水口102与所述驱动电机104之间。同时所述固定圈上沿所述传动轴103的长度方向固定有分离网106，所述进水口102的一端设置在所述第一筒体101的外部，另一端则向固定圈所在的方向弯折并延伸至固定圈的另一侧。所述分离网106则是用于将固液混合的液体分离成：悬浮物等固体位于分离网106内，液体则位于所述分离网106的外侧。为了能够将位于分离网106内部的悬浮物等固定输送到排污单元3内，故在所述传动轴103上设置有输送板105，所述输送板105呈螺旋状缠绕在所述传动轴103上，同时所述分离网106的内壁与所述输送板105之间构成线接触。所述输送板105既能够将悬浮物等固体输送到排污口处，又能够在混合液中产生对流，便于将液体甩到分离网106外部去，达到更好的分离效果。
进水口102与所述分离网106的内部相连通，即待处理水通过进水口102后直接进入到分离网106的内部；所述分离网106的另一端延伸至排污口内，同时所述传动轴103和输送板105靠近排污口的一端延伸至分离网106外，将位于分离网106的内部物体直接输送到排污口内；
同时，因为既要排出固体悬浮物又要将分离出来的液体排出，故两个出口是相互没有关联，应当满足以下需求：第一筒体101远离进水口102的一端对称开设有第一出水口，所述第一出水口通过连接管与所述二级过滤单元2的进口相连通，第一出水口位于第一筒体101的筒壁与分离网106之间，用于转移经过初级过滤的水。
在进一步的实施例中，为了能够使分离后的液体更好的、更顺畅的从一出水口中排出，发明人做了以下改进：所述分离网106的外侧壁等距离的固定有环形圈107，所述环形圈107的两侧壁上设置有多个柱体108，当分离网106在驱动电机104的作用下自转时，所述环形圈107和所述柱体108在液体能够增加水的对流，加强水的流动，流向第一出水口，并排出。
在进一步的实施例中，所述分离网106为圆台结构，所述分离网106的直径从进水口102至排污口逐渐减小。即分离网106到第一筒体101之间的距离从进水口102至第一出水口逐渐增加，因此考虑到压力之间变小，所以水流则更倾向于向第一出水口处流动，便于排出。
在进一步的实施例中，所述二级过滤单元2包括：第二筒体201，所述第二筒体201的内部从上至下依次设置有第一吸附腔202和第二吸附腔203。所述第一吸附腔202上开设有进水口102，所述进水口102通过连接管与所述第一出水口相通。所述第二吸附腔203的底部开设有排水口205，用于排出处理后的水。
所述第一吸附腔202内设置有若干个水质滤芯207，所述水质滤芯207为PP棉滤芯，呈等距离的安装在两个承载盘之间，所述水质滤芯207用于去除经过一级过滤单元1处理后残留在水质中的细小颗粒；所述两个承载盘和水质滤芯207位于所述第一吸附腔202内如图5所示。所述滤芯由滤网包裹而成。
所述第二吸附腔203的内部设置有导流壳体206，所述导流壳体206与所述第一吸附腔202相互连通，所述导流壳体206的内径从上之下依次变小，且所述导流壳体206的内部设置有多层滤膜，所述导流壳体206的底端与所述排水口205相通；所述多层滤膜则是用于吸附水中的氯元素、微菌。导流壳体206的竖截面呈倒锥形，是为了是水在重力和压力的挤压下，增加与滤膜的接触面积和延长其过滤时间，加强过滤的力度。所述滤膜上填充有硅铝酸盐吸附剂、活性炭中的一种或者几种。所述滤网为多层，所述滤网的外径的变化趋势与所述导流壳体的内径的变化趋势相一致，所述滤网通过卡箍紧密固定在所述导流壳体的内部。
在进一步的实施例中，为了更好的清理被分离出来的固体悬浮物，如图9所示，所述排污单元3包括：连接体301，所述连接体301固定在所述排污口处并与所述排污口相通，所述连接体301的内部固定有第一碾压盘302，所述第一碾压盘302的中心位置为敞口结构，以所述敞口结构为中心从内至外在所述第一碾压盘302上设置有若干个直径不同的第一环形凸起307，所述第一环形凸起307与敞口结构为同心圆。所述连接体301的内部还设置有第二碾压盘303，以所述第二碾压盘303的圆心为中心从内至外在所述第二碾压盘303上设置有若干个直径不同的第二环形凸起308，所述第二环形凸起308与敞口结构为同心圆。所述第一环形凸起307与所述第二环形凸起308交错分布，相互卡接。为了能够驱动第二碾压盘303转动，故所述第二碾压盘303传动连接有转动轴304，所述转动轴304传动连接于转动电机305。为了能够将碾压破碎后的颗粒排出，所述连接体301上开设有物料口306。悬浮物经排污口进入到连接体301内，在转动的第一碾压盘302和第二碾压盘303的配合下实现对悬浮物的碾压变小，并从物料口306排出。
为了能够将物料从敞口结构中顺利的排出到物料口306处，发明人做了以下改进：所述第二环形凸起308上等距离的开设有向内部凹陷的通孔309，所述通孔309的深度等于所述第二环形凸起308的高度；当第一环形凸起307与所述第二环形凸起308相互卡接时，位于最内侧的为第二环形凸起308，位于最外侧的为第一环形凸起307。
同时，还满足以下条件：所述第一环形凸起307的高度略低于所述第二环形凸起308的高度，所述第一环形凸起307的厚度略小于两个相邻的第二环形凸起308之间的间距，所述第二环形凸起308的厚度略小于两个相邻的第一环形凸起307之间的间距。即在碾压时，固体悬浮物的路径如下：被分离出来的悬浮物经排污口进入到连接体301内，由于第二碾压盘303在转动电机305的作用下，相对第一碾压盘302转动，且转动的过程中，也是第二环形凸起308在相邻的第一环形凸起307之间的卡槽内转动；悬浮物首先经过通孔309转移到第二环形凸起308与第一环形凸起307之间，然后再经过第一环形凸起307与第二碾压盘303之间，依次类推，即通过各种缝隙向第二碾压盘303的边缘处移动，最终从物料口306排出，当物料从通孔309进入到第一碾压盘302与第二碾压盘303重叠的部分直至排出，整个过程都是受到第一环形凸起307和第二环形凸起308的碾压作用，将大颗粒变成极小颗粒并排出。
污水处理装置的处理方法，具体包括以下步骤：
步骤一、待处理的水源通过进水管进入到一级过滤单元1，在一级过滤单元1内部实现对悬浮物的过滤并排出：待处理水从第一筒体101的进水口102直接进入到分离网106的内部，同时分离网106在所述驱动电机104的驱动下，和所述输送板105一起发生自转同时会对位于分离网106内部的水源产生水流，在水流的作用下，水会带着极小颗粒被甩出到分离网106外，而颗粒较大的悬浮物则仍在被圈在分离网106内；
步骤二、位于分离网106内部的悬浮物在自转的输送板105的作用下，被输送到排污口内，考虑到所述传动轴103和输送板105靠近排污口的一端延伸至分离网106外，即悬浮物会准确的被输送到与排污口相连的排污单元3内进行处理，执行步骤四；
步骤三、甩出到分离网106的水，在环形圈107的两侧壁上的多个柱体108产生流动的作用下或者在呈圆台结构的分离网106产生的压力差的作用下，顺畅的流向第一出水口处，并通过连接管转移到二级过滤单元2中去，执行步骤五；
步骤四、被分离出来的悬浮物经排污口进入到连接体301内，由于第二碾压盘303在转动电机305的作用下，相对第一碾压盘302转动，且转动的过程中，也是第二环形凸起308在相邻的第一环形凸起307之间的卡槽内转动；悬浮物首先经过通孔309转移到第二环形凸起308与第一环形凸起307之间，然后再经过第一环形凸起307与第二碾压盘303之间，依次类推，即通过各种缝隙向第二碾压盘303的边缘处移动，最终从物料口306排出，当物料从通孔309进入到第一碾压盘302与第二碾压盘303重叠的部分直至排出，整个过程都是受到第一环形凸起307和第二环形凸起308的碾压作用，将大颗粒变成极小颗粒并排出；
步骤五、达到二级过滤单元2中的水，先进过第一容腔内的水质滤芯207，对在一级过滤单元1中没有处理到的细小颗粒进行吸附；
