一种废水处理系统及废水处理工艺

A Kind of Wastewater Treatment System and Wastewater Treatment Process

摘要: 随着现代工业的不断发展，大量难以分解的固体颗粒、重金属、有机废弃物等被排放入水中，现有的污水处理工艺主要依靠传统工艺，处理效率低下，设备损耗严重，导致非常高的处理成本。本技术建立了一种新型废水处理系统，包括沉淀装置、过滤装置、消毒和净化装置。在关键净化装置中采用基于活性炭的过滤剂处理污水中难以去除的有机小分子污染物、重金属和固体颗粒。活性炭与硅藻土、沸石通过共混合、烘干工艺，活性炭和硅藻土可以均匀的覆盖在沸石的表面，大大增加了污水处理剂的表面积，同时充分利用活性炭和硅藻土的吸附效果，对难以出去的固体颗粒、有机污染物处理效果更好。

Abstract: With the rapid development of modern industry, a large number of solid particles, heavy metal ions, and organic waste are discharged into the water. The current used wastewater treatment process encounters low efficiency and serious equipment loss, which leads to high treatment cost. This paper discloses a wastewater treatment system, which comprises a settling device, a filtering device, a sterilizing and purifying device. In the key purifying device, an active carbon-based filter agent is used to remove the solid particles, heavy metal ions, and organic waste presented in wastewater. Activated carbon, diatomite and zeolite are combined and dried to produce the sewage treatment agent, by which the activated carbon and diatomite can be uniformly covered on the surface of the zeolite. This method greatly increases the surface area of sewage treatment agent and enhances the adsorption effect of activated carbon and diatomite, thereby resulting in high efficiency to remove the solid particles and organic pollutants in wastewater.
