环境污染控制研究

摘要

(小一黑体)

二氧化氯作为预氧化剂的优越性已为共识,但是,二氧化氯在预氧化过程中产生的主要副产物为亚氯酸盐,一定浓度的亚氯酸盐对人体健康产生负面影响。ClO2用于预氧化处理并非如后消毒一样产生一定比例的亚氯酸盐,亚氯酸盐本身具有较强的氧化作用,它不仅可以与具有还原性的无机离子发生反应,生成氯离子,且对某些菌类具有良好灭活效果。研究预氧化过程中亚氯酸盐的反应规律,控制亚氯酸盐的量或者去除亚氯酸盐,并达到一定的精度要求,将是未来的一个研究方向。对于ClO2-预氧化水中的亚氯酸盐研究,一是可以充分利用,减少预氧化剂的投加量,降低制水成本;二是可为去除其提供参考,增加有机污染物去除的方案,提供更全面的去除方案。

本课题以某水库的原水为研究对象,以亚氯酸盐为预氧化剂,通过改变原水的水质指标,研究了亚氯酸盐预氧化微污染水过程中亚氯酸盐对水质的氧化效果。研究表明:ClO2-具有净化水质的能力,去除CODMn效果较高,对UV254的去除率影响较大,在一定范围内,使预氧化的水样pH稍微显酸性,那样有助于亚氯酸盐的预氧化,亚氯酸盐对水中的铁也有消减作用,所以ClO2-不可以单独作为饮用水的预氧化剂,但在ClO2-预氧化工程中可考察充分利用其氧化性,以达到减少ClO2投加量的目的。 关键词:亚氯酸盐,预氧化,CODMn,Fe2+,UV254

SUMMARY OF REPORTS ON WATER

TREATMENT METHODS(小一)

Abstract

Chlorine dioxide as a pre-oxidant has the advantages of a consensus, however, chlorine dioxide pre-oxidation process in the main by-product of chlorite, a certain concentration of chlorite have a negative impact on human health. ClO2 for pre-oxidation treatment is not as sanitized as a certain percentage of chlorite, chlorite itself has a strong oxidation, it not only with a reduction of inorganic ions react with chlorine ions, and inactivation of certain fungi with good results. Pre-oxidation process of the reaction rule in Central Asia perchlorate, the amount of control or removal of chlorite chlorite, and up to a certain precision, will be a future research direction. Pre-oxidation for ClO2-chlorite in water research, one can take advantage of to reduce the dosage of the pre-oxidant to reduce the cost of water; the second is to provide a reference for the removal of the increased removal of organic pollutants in the program provide more comprehensive removal program.

The topics to a raw water reservoir for the study, the chlorite to pre-oxidant, by changing the raw water quality indicators, pre-oxidation of the chlorite process of micro-polluted water in Central Asia chlorate oxidation effect of water quality. Studies have shown that: ClO2-has the ability to purify water, remove the effect of higher CODMn, UV254 removal of a greater impact within a certain range, so that pre-oxidation of water pH is slightly acidic, so helps to chlorite salts of the pre-oxidation, chlorite in water also reduce the role of iron, so can not ClO2-alone as pre-oxidant water, but the pre-oxidation in ClO2-engineering can take advantage of the oxidation study, in order to achieve reduced ClO2 dosage purposes.

Key words: chlorite, pre-oxidation, CODMn,Fe2+,UV254
