Adsorption And Degradation Behavior Of Phenol On Natural Sediment And Typical Minerals

With the high speed development of industrialization, more and more organicpollutants were discharged into water, resulting in the water pollution in major riversand lakes in China. The shortage of water resources and the pollution of rivers andlakes are increasingly serious,which began to restricts the development of the humanrace. This paper studies the adsorption behavior of the pollutant in the river whiletransfer with the river water in the river sediments, and analysis environmentalbehavior of the pollutants in water-sediment, water-suspended particles betweendifferent phase.Phenol is a typical of the highly toxic organic compounds which be widelyapplied in the industrial production, it has a very great harm to environment due to itdischarged into the water as industrial effluents too much. In this paper, phenolwastewater was simulated discharged into water, and the adsorption of sediment alsobe influenced by many kinds of factors. Study the effect factors on phenol adsorptionof sediments, the combination of organic matter can obviously reduced bioavailabilityof pollutants. Inorganic mineral components in sediment occupies a significantportion, which is also a key factor in adsorption effect.This paper is divided into three sections, the first section is study on distributionbehavioral research of water-sediments phases of phenol in river water, consideringthe actual environmental factors such as water temperature, pH value, surface activeagent, sediment properties, and explain the distribution and adsorption behavior ofpollutants in the river water environment. The second section is through the synthesisof common inorganic mineral manganese dioxide as oxidant to study theenvironmental behaviors of phenol in water-suspended particles, and exploreadsorption behavior of such compounds in two phases of solid and liquid, andinvestigate different influence factors on the phenol degradation by manganesedioxide. In the third section, the representative mineral montmorillonite was choosedto study adsorption effect of phenol, investigate the general rule of adsorptionbehavior of compounds in two phases of solid and liquid. Through simulating some factors in actual water, some effect factors like water temperature, pH, ionic strengthand coexistence surfactant were investigated. The main mechanism of phenoladsorption effect was analysed,which has positive significant to environmentevaluation and pollution management.
