Abstract: The tested rice field in the Changsha County is an typical acidic Cd-polluted paddy field , and the rice has a high accumulation of Cd from the soil[1]. The production of cadmium rice will bring a risk to food safety and human health. In this paper, the characteristic of the selected Cd-polluted paddy field was analyzed and the risk of pollution was evaluated. Then, according to the analysis and evaluation results, the restoration and treatment research was carried out, which used the whole-process control mode (front-end irrigation water purification, middle-end stabilization control, and end-end plant enrichment). The results showed that the experimental rice field was a high-risk field, and the Cd in rice decreased by 67.24% after the application of whole-process control mode. Available Cd of soil decreased by 38.10% and the yield of rice increased by 8.85%.The removal rate of total Cd was 3.17%~8.45% in soil, and the bio-concentration factor (BCF) of Cd in the rape plant was 2.69~3.43. By estimation, the direct remediation cost of this case is 5100 yuan /hm2 per quarter. This study is of great significance for the establishment of a complete set of whole-process control integration technology for the remediation of contaminated rice fields and its promotion and demonstration.
