Heavy metal pollution has pervaded many parts of the world, especially developing countries such as China. The discharge of wastewater containing heavy metals will cause soil pollution for a long time and harm to human health. Soil washing is an environmentally feasible and cost-effective approach for the clean-up of sites contaminated with heavy metals. As a relatively environmental protection agent, surfactants are widely used in soil washing. This paper generalized the methods of remediation of soil from heavy metals, expounded the mechanisms of soil washing by surfactant and the types of surfactants and summarized the application of different surfactants in washing heavy metals from soil. Finally, the application prospects and development trends of surfactant washing heavy metals from soil have been prospected.

In the recent years, antibiotics and heavy metals have become common pollutants in soil. Plant-microbial remediation is promising for the management of antibiotics and heavy metals pollution in soil. This paper talks about the mechanization of plant-microbial remediation, finds the advantages and disadvantages about plant-microbial technology, summarizes the method of selection of the plant and microbial, influential factors, and discusses the future research priorities of plant-microbial remediation.

The use of microbes to change the concentration of heavy metals in soil and improve the ability of plants to deal with elevated metals concentrations has significant economic and ecological benefits. This paper reviews the origins and toxic effects of heavy metal pollution in soil, and describes the heavy metal accumulation mechanisms of microbes, and compares their different bioconcentration abilities. Biosorption, which depends on the special structure of the cell wall, is found to be the primary mechanism. Furthermore, Escherichia coli are found to adsorb more heavy metals than other species. Factors influencing microbial treatment of wastewater and soil containing heavy metals include temperature, pH, and different substrates. Finally, problems in the application of microbial treatment of heavy metal contamination are considered, and possible directions for future research are discussed.

Remediation Of Soil

According to the primary study on the As contamination in soil and crops including potato and pea in tin tailings in Gejiu area, Yunnan Province, it has been found that concentrations of As in rhizosphere far exceed Chinese National Grade Ⅲ standard of soil environmental quality of China (GB 15618-1995). It also has been found that the Ferns were living in the tin tailings suffered from the contamination of heavy metals. Compared with the limit of national criteria for food sanitation in China, the concentrations of As in edible parts of ferns are 90 times. Therefore, the remediation of soil based on geochemical distribution characteristics of heavy metal in the tailings is demanded. And avoiding crops-planting in the tailings to reduce the diffusion of heavy metal contamination in food chain of mining area is necessary.

Heavy metal pollution in soil has seriously affected the living environment of human beings. Among all heavy metal pollution, cadmium (Cd) is one of the most difficult to migrate pollutants in soil. In China, more than 11 provinces and 25 regions are rich in cadmium in the soil. At present, many researchers are looking for a proper Cd pollution remediation method. Through literature review and comparative analysis, this study summarized the main repair methods, including physical repair (digging and filling, electro kinetic remediation, frozen soil remediation technology, stabilization technology), chemical curing technology (chemical healing technology, chemical extraction), bioremediation technology (Phytoremediation technology, microbial remediation technology, animal repair technology), and joint repair (Chelating agent phytoremediation, microbial remediation). Finally, we explored the principles of these methods and compared their advantages and disadvantages. It was found that the application and selection of different treatment technologies depended on Cd rich soil area, Cd pollutant content, treatment time and other factors. In the future, the remediation of soil cadmium pollution should be scientifically selected according to the local actual situation and pay attention to the joint application of various methods.
