摘要：

利用硅藻改性使硅藻表面不平衡电位能中和悬浮离子的带电性,加上硅藻巨大的表面积和较强的吸附力,使污水中细微和超细微物质吸附到硅藻表面,形成链式结构,凝集成较大的絮花,使污染物质和细菌迅速下沉与水体分离,在专用设备的作用下自然形成柔性过滤层,从而达到将污水处理为清水的目的。该技术占地少,投资小,运行费用低,耐冲击,出水水质稳定可靠,只需简单消毒即可达到中水回用标准的要求。

Abstract:

Using the modification of diatom can make the unbalanced potential energy of the diatom surface neutralize the electrification of suspended ions. In addition to it, the large surface and strong absorbency can make the fine and ultrafine substances be absorbed on the diatom surface, forming a chain structure, and coagulating bigger floccules. In this case, the polluted substances and bacteria can sink quickly and be separated from the water body. A soft filter layer will be formed naturally by the action of the special equipment, so as to make the sewage be treated and become clean water. This technique is characterized by occupying less area, needing less investment, enduring greater impact, spending lower running cost and having more stable effluent water quality. Only simple disinfection is needed in order to meet the requirement of the regenerated reused water standard.

Key words: diatomite water treatment agent, reuse of regenerated, water wastewater treatment
