【摘要】：自然水體生物膜是影響重金屬在水環(huán)境中行為的重要因素。不同環(huán)境生長(zhǎng)的生物膜其性質(zhì)、狀態(tài)差異很大,生物膜吸附重金屬的量不僅與生物膜的數(shù)量,而且與生物膜的性質(zhì)有關(guān)。本論文首次系統(tǒng)研究確定了不同時(shí)間、不同深度、不同季節(jié)和不同水體培養(yǎng)的生物膜上鐵、錳氧化物、有機(jī)質(zhì)的生長(zhǎng)規(guī)律及吸附特性,比較了有機(jī)質(zhì)的不同表征方法及相關(guān)關(guān)系,獲得了膜上微生物物種、生物量及其變化信息,討論了水中懸浮顆粒物對(duì)生物膜上鐵、錳氧化物含量、形成和鉛、鎘吸附特性的影響,及pH 值、水溫、溶解氧、光照等環(huán)境條件對(duì)生物膜上主要組分生長(zhǎng)和吸附特性的意義和影響,對(duì)于深入了解自然水體生物膜的形成機(jī)制及水環(huán)境中重金屬的形態(tài)、分布及遷移轉(zhuǎn)化規(guī)律具有重要意義。
[Abstract]:Natural water biofilm is an important factor affecting the behavior of heavy metals in water environment. The properties and states of biofilms grown in different environments vary greatly. The amount of heavy metals adsorbed by biofilms is not only related to the amount of biofilms but also to the properties of biofilms. For the first time, the growth and adsorption characteristics of iron, manganese oxide and organic matter on biofilms cultured in different time, different depth, different seasons and different water bodies were studied systematically in this paper. Different characterization methods of organic matter and their correlation were compared. The microbial species, biomass and their variation information were obtained. The effects of suspended particulate matter on iron and manganese oxide content, formation and lead in biofilm were discussed. The effects of pH value, water temperature, dissolved oxygen and light on the growth and adsorption characteristics of major components on the biofilm. It is of great significance to understand the formation mechanism of biofilm and the speciation, distribution, migration and transformation of heavy metals in water environment.
