Decontamination of dense nonaqueous-phase liquids in groundwater using pump-and-treat andin situchemical oxidation processes: a field test

Abstract

The combination of pump-and-treat and in situ chemical oxidation processes can effectively accelerate the remediation of DNAPL pollutant in groundwater.

Ti/CoTiO3-TiO2 for Efficient Degradation of Refractory Organic Dyes: Synthesis, Characterization, and Electrocatalytic Properties

“…With the rapid growth of population and development of industrialization process, enormous organic dyes wastewater commonly originated from textile, printing, cosmetics and pharmaceutic industries have triggered severe negative impact on the ecosystem and human health. Due to its high toxicity, refractory, and variability in composition, it is difficulty to be effectively treated by some conventional methods, such as biological oxidation, 1 adsorption, 2 chemical oxidation, 3 and so on. By comparison, advanced oxidation processes (AOPs) such as photocatalysis, Fenton oxidation and electrocatalytic oxidation technique show desirable removal performance for the refractory organic pollutants.…”
