摘要
目前使用城市污水再生作为电厂循环水的电厂多数采用石灰处理工艺,也有的采用超滤工艺,本文则介绍采用混凝+MF连续微滤膜+臭氧+部分RO反渗透膜的处理工艺。该工艺有效地解决了冬季出水水质溶解性总固体TDS指标和总硬度指标偏高的问题。因此特别适合于污水水质随季节变化明显的城市。
Reuse of treated municipal sewage as circulating cooling water of fossil-fired power plants is a very theme worthy to be studied and spread because of the water shortage in most areas of China.This paper presents a process using coagulating +MF+ozone+partial RO to deal with the recycled sewage after treated preliminarily in sewage treatment plant.The process solves effectively the problem of higher TDS and higher total hardness in product water in winter,thus is especially fit for cities where sewage quality changes obviously with seasons.
