Abstract

The invention discloses a method for pretreating source water with combined pollutants of high-concentration ammonia nitrogen, high-concentration organic matter and manganese, belonging to the field of drinking water treatment and aiming at solving the problem of the combined pollution of high-concentration ammonia nitrogen, high-concentration organic matter and manganese in the source water. The method includes the steps as follows: firstly, adding potassium permanganate composite (PPC) in the source water for chemical preoxidation; and secondly, introducing the source water after chemical preoxidation into a biological aerated filter for treatment, wherein the biological aerated filter takes volcanics as fillers, so that pretreatment of the source water is realized. The method achieves permanganate index removal rate of 20%-35% and ammonia-nitrogen removal rate of above 80%, and obviously relieves pollution-removal load of a follow-up technology.

Description

technical field

[0001] The invention belongs to the field of drinking water treatment, and in particular relates to a method for pretreating source water with high ammonia nitrogen, high organic matter and manganese compound pollution. Background technique

[0002] With the rapid development of industry and agriculture, the problem of water pollution caused by human factors has become increasingly prominent. The overall water quality of the seven major water systems in my country, including the Yangtze River, Yellow River, Pearl River, Songhua River, Huaihe River, Haihe River and Liaohe River, is seriously polluted. The water quality of many river networks is used as drinking water sources for people. threat to life and security. It is difficult to treat source water containing high ammonia nitrogen, high organic matter and manganese complex pollution by conventional processes. Contents of the invention

[0003] The invention provides a method for pretreating source water ...
