Description
技术领域Technical Field
本发明涉及一种污水净化处理装置，特别涉及一种采用磁分离方法净化处理污水的设备，属于污水处理设备领域。The invention relates to a sewage purification treatment device, in particular to a device for purifying sewage using a magnetic separation method, and belongs to the field of sewage treatment equipment.
背景技术Background Art
目前一般采用以生活污泥法为代表的生化工艺处理城镇污水，该工艺对CODcr、BOD5有良好的去除效果，但脱氮除磷效果欠佳，难以达到国家一级排放标准，必须采取进一步的化学强化处理才能排放。另外，生化处理还存在污水停留时间长、单位面积处理能力小、污水处理厂建设与扩容受空间限制等问题。At present, the biochemical process represented by the domestic sludge method is generally used to treat urban sewage. This process has a good removal effect on COD cr and BOD 5 , but the nitrogen and phosphorus removal effects are poor, and it is difficult to meet the national first-level emission standards. Further chemical enhanced treatment must be taken before it can be discharged. In addition, biochemical treatment also has problems such as long sewage retention time, small treatment capacity per unit area, and space limitations on sewage treatment plant construction and expansion.
针对普通化学沉淀法除磷水力停留时间较长、设施占地面积等问题，自20世纪70年代起，人们就开展了一系列磁种絮凝-高梯度磁分离去除污水中磷的研究，并取得了很好的结果。此方法即先在污水中投加磁粉和药剂，使磁粉与污水中的污染物絮凝成团，再利用磁分离设备从污水中将絮凝成团的杂质吸附分离出来，以实现污水的净化。In view of the long hydraulic retention time and facility footprint of phosphorus removal by conventional chemical precipitation, a series of studies on the removal of phosphorus from sewage by magnetic flocculation-high gradient magnetic separation have been carried out since the 1970s, and good results have been achieved. This method is to first add magnetic powder and reagents to the sewage to flocculate the magnetic powder and pollutants in the sewage, and then use magnetic separation equipment to adsorb and separate the flocculated impurities from the sewage to achieve sewage purification.
高梯度磁分离与传统工艺相比，处理速度快，处理能力大；对磷、细菌有良好的去除效果，出水水质好；设备紧凑(仅为传统系统的1/3)，占地面积少，容易实现工艺一体化、自动化。Compared with traditional processes, high-gradient magnetic separation has faster processing speed and greater processing capacity; it has a good removal effect on phosphorus and bacteria, and the effluent quality is good; the equipment is compact (only 1/3 of the traditional system), occupies less space, and is easy to achieve process integration and automation.
磁分离水体净化技术的关键是设备本身的性能。目前，工程应用中的磁分离水体净化设备按永磁材料的集成方式主要分三种，一是磁棒分离净化设备，二是磁滚筒分离净化设备，三是磁环分离净化设备。磁棒分离净化设备磁场强度高，适合于超细磁性杂质的分离，但卸渣过程比较烦杂，难以适应大水量连续处理要求；磁滚筒分离净化设备由一个磁滚筒和污水槽、刮渣片组成，污水流经磁滚筒外表面，污水中的磁性颗粒物(或磁性絮团)被磁滚筒吸附分离；磁环分离净化设备由多个磁环组合而成，所用永磁材料为稀土永磁磁块，污水流经磁环空间隙，污水中的铁磁性颗粒物被磁环吸附，污水得到净化。以上三种装置共同的缺点是流经时间较短，吸附能力有限，影响磁种回收效果。The key to magnetic separation water purification technology is the performance of the equipment itself. At present, the magnetic separation water purification equipment in engineering applications is mainly divided into three types according to the integration method of permanent magnetic materials: magnetic rod separation purification equipment, magnetic drum separation purification equipment, and magnetic ring separation purification equipment. The magnetic rod separation purification equipment has a high magnetic field strength and is suitable for the separation of ultrafine magnetic impurities, but the slag unloading process is relatively complicated and difficult to adapt to the requirements of large-scale continuous water treatment; the magnetic drum separation purification equipment consists of a magnetic drum, a sewage tank, and a scraper. The sewage flows through the outer surface of the magnetic drum, and the magnetic particles (or magnetic flocs) in the sewage are adsorbed and separated by the magnetic drum; the magnetic ring separation purification equipment is composed of a plurality of magnetic rings, and the permanent magnetic material used is a rare earth permanent magnetic block. The sewage flows through the gap between the magnetic rings, and the ferromagnetic particles in the sewage are adsorbed by the magnetic rings, and the sewage is purified. The common disadvantages of the above three devices are that the flow time is short and the adsorption capacity is limited, which affects the magnetic seed recovery effect.
发明内容Summary of the invention

The first cover and the second cover are fixed to the driving device and do not move, and the matrix ring rotates with the rotating shaft of the driving device so that each grid matrix enters the flushing water opening (i.e., the first flushing water inlet and the second flushing water inlet), the flushing water opening position remains unchanged, and each grid matrix is backwashed here as it turns.
前述的一种连续式高梯度磁分离装置中，所述第一盖体上设置有第一冲洗水出口和第二冲洗水出口，第一冲洗水出口和第二冲洗水出口位于第一盖体中心线的两侧。In the aforementioned continuous high-gradient magnetic separation device, the first cover body is provided with a first flushing water outlet and a second flushing water outlet, and the first flushing water outlet and the second flushing water outlet are located on both sides of the center line of the first cover body.
前述的一种连续式高梯度磁分离装置中，所述第一盖体上设置有多个开口，其中包括有第一进水口、第一出水口、第二进水口、第二出水口，相邻的第一进水口与第二进水口位于第一冲洗水出口的两侧，相邻的第一出水口和第二出水口位于第二冲洗水出口的两侧。In the aforementioned continuous high-gradient magnetic separation device, a plurality of openings are provided on the first cover body, including a first water inlet, a first water outlet, a second water inlet, and a second water outlet.

本发明的的工作原理：The working principle of the present invention:
如图2所示，带有磁性物质的水18由上盖的第一进水口6流入矩阵环3中，通过矩阵环3的一个设置在扇形矩阵4上方的过水口401进入填充有钢丝的该扇形矩阵4内，然后通过设置在相邻扇形矩阵下方的过水口流向下一个扇形矩阵，最终由第一出水口7流出。本发明这种带有过水口且内部填充有钢丝或铁丝的扇形矩阵4结构设计形式可增加污水流经路径，进而延长污水停留在矩阵环3中的时间，使污水中的磁性物质与高梯度磁场(高梯度磁场由设置在第一盖体1和第二盖体2上的永磁体16及填充在若干扇形矩阵4内的钢丝或铁丝形成)有更长时间的接触，以使更多的磁性物质能够被填充在若干扇形矩阵4内的钢丝或铁丝所捕获。As shown in FIG2 , water 18 with magnetic substances flows into the matrix ring 3 from the first water inlet 6 of the upper cover, enters the fan-shaped matrix 4 filled with steel wires through a water outlet 401 of the matrix ring 3 arranged above the fan-shaped matrix 4, then flows to the next fan-shaped matrix through the water outlet arranged below the adjacent fan-shaped matrix, and finally flows out from the first water outlet 7. The structural design form of the fan-shaped matrix 4 with a water outlet and filled with steel wire or iron wire in the present invention can increase the flow path of sewage, thereby prolonging the time that sewage stays in the matrix ring 3, so that the magnetic substances in the sewage have a longer contact with the high gradient magnetic field (the high gradient magnetic field is formed by the permanent magnets 16 arranged on the first cover body 1 and the second cover body 2 and the steel wire or iron wire filled in the fan-shaped matrix 4), so that more magnetic substances can be captured by the steel wire or iron wire filled in the fan-shaped matrix 4.
为冲洗扇形矩阵4内填充的钢丝捕获的磁性物质，使冲洗水17由第二盖体2的第一冲洗水进口11进入，然后从第一盖体1的第一冲洗水出口8流出，以便于去除矩阵中的磁性物质。To flush the magnetic material captured by the steel wires filled in the fan-shaped matrix 4, flushing water 17 enters from the first flushing water inlet 11 of the second cover body 2 and then flows out from the first flushing water outlet 8 of the first cover body 1, so as to remove the magnetic material in the matrix.
本发明这种带有过水口401且内部填充有钢丝或铁丝的扇形矩阵4结构设计形式，可以对每个扇形矩阵4单独进行冲洗，同时本发明这种磁分离装置可不停机运行；相邻的扇形矩阵4上过水口401的开设方向相反的结构设计可以改变污水的流经路径，增加流经时间，增强吸附能力，并且降低了堵塞的可能性。The structural design of the fan-shaped matrix 4 with water outlets 401 and filled with steel wire or iron wire in the present invention can flush each fan-shaped matrix 4 individually, and the magnetic separation device of the present invention can operate without stopping; the structural design of the water outlets 401 on adjacent fan-shaped matrices 4 with opposite opening directions can change the flow path of sewage, increase the flow time, enhance the adsorption capacity, and reduce the possibility of blockage.
