| Abstract: | Situ remediation on contaminated soil is an important part for environment pollution control. To deal with purification efficiency and lower water quantity caused by soil pollution in sewage treatment process, this paper studied technology of situ remediation by adding ash, planting, physical rehabilitation and adding rare earth element. The results showed that several repair techniques had a certain effect on sewage land treatment system where soil pollution occurred. For the sewage land treatment facility, the removal efficiency of NH3-N,TP and BOD5 increased respectively by 3.07 percent to 12.55 percent,2.03 percent to 10.59 percent and 4.07 percent to 13.7 percent. The repair capacity of aeration technology was best, the next was planting and adding rare earth element, and the worst was adding ash. |
