Description

一种防结垢电渗透电极板装置Anti-scaling electro-osmosis electrode plate device 技术领域Technical field
本申请涉及污水处理行业,特别是一种防结垢电渗透电极板装置。This application relates to the sewage treatment industry, in particular to an anti-scaling electro-osmosis electrode plate device.
背景技术Background technique
目前,我国各城镇污水处理厂的工艺仍然以活性污泥、生物法为主,在污水的各级处理过程中,需要对含有细菌及各种寄生虫卵等有害物质进行处理。污水处理中,污水的主要水主要分为毛细水、间隙水、表面附着水和内部水。At present, the process of sewage treatment plants in cities and towns in my country is still based on activated sludge and biological methods. In the process of sewage treatment at various levels, it is necessary to treat harmful substances such as bacteria and various parasite eggs. In sewage treatment, the main water of sewage is mainly divided into capillary water, interstitial water, surface adhesion water and internal water.
单纯的机械脱水方式主要可以去除的是毛细水和间隙水,其余的水分需要通过消耗热量或者通过进一步的物理、化学、生物等方法去除。因而,即使经过机械脱水之后,由于仍然含有大量水分,污泥的体积仍然很大。因此,需要寻找一些合理有效的脱水方式来脱除污泥中的剩余水分,以尽可能的减小污泥的体积,从而为污泥的后续处理及运输、排放等降低成本。The pure mechanical dehydration method can mainly remove capillary water and interstitial water, and the remaining water needs to be removed by consuming heat or by further physical, chemical, biological and other methods. Therefore, even after mechanical dehydration, the volume of sludge is still large because it still contains a lot of water. Therefore, it is necessary to find some reasonable and effective dewatering methods to remove the remaining moisture in the sludge, so as to reduce the volume of the sludge as much as possible, so as to reduce the cost for the subsequent treatment, transportation, and discharge of the sludge.
电渗透脱水技术,就是利用外加的直流电场,从而增强物料脱水性能的方法。其最早被应用于土壤的原位修复中,主要是用于去除土壤中的有机污染物以及重金属物质。由于电渗透技术具有良好的脱水性能,因而近来年越来越多的研究人员将其应用于污泥脱水当中,达到对污泥进行深度脱水的目的。Electro-osmosis dehydration technology is a method that uses an external DC electric field to enhance the dehydration performance of materials. It was first used in in-situ soil remediation, mainly to remove organic pollutants and heavy metal substances in the soil. Due to the good dewatering performance of electroosmosis technology, more and more researchers have applied it to sludge dewatering in recent years to achieve the purpose of deep dewatering of sludge.
但是电渗透脱水过程中,存在污泥加被加热且阴极呈碱性,进而会在阴极网的一侧出现结垢的情况,这样直接导致电阻升高、工作效率明显降低和过滤性能变差的情况。实际使用过程中可能1~3天就需要进行一次清洗除垢过程。However, in the electro-osmosis dehydration process, the sludge is heated and the cathode is alkaline, which will cause fouling on one side of the cathode net, which directly leads to an increase in electrical resistance, a significant decrease in work efficiency and poor filtration performance. Happening. In actual use, a cleaning and descaling process may be required for 1 to 3 days.

该方案的具体组成及原理是:The specific composition and principle of the program are:

The fouling condition or the water content of the mud cake after desliming under the actual working conditions of the plate and frame filter press determines the fouling condition of the cathode plate. When it is determined that the scale needs to be cleaned up, the control cabinet controls the friction vibration system to move to a suitable position on the walking frame, the folding structure turns the friction plate 90° to contact the front of the cathode mesh, and starts the rotation head and the cathode mesh to rub for about 10 seconds. Remove the solid dirt of the cathode mesh. After cleaning the first piece, the folding structure turns the friction plate up and moves to the next plate frame, and again turns the friction plate 90° to contact with the front of the cathode net to start the rotation head to drive the friction plate and the cathode plate to rub against to achieve the function of descaling. A descaling work requires multiple cycles of the above steps to complete the descaling work of the cathode plate of the electroosmotic plate and frame filter press.
