土壤污染的原位修复是环境污染治理领域中重要部分，本文针对污水处理过程中土壤污染造成的净化效率、出水量降低，分别进行添加草木灰、栽种植物、物理修复及添加稀土元素等土壤原位修复技术试验研究。试验结果表明：上述几种修复技术对于已发生土壤污染的污水土地处理系统均有一定修复效果，经修复后的污水土地处理设施NH3-N去除效果提高3．07％-12．55％；TP去除效果提高2．03％～10．59％；BOD5去除效果提高4．07％～13．70％。修复能力最高的为曝气技术，其次为同时栽种植物和添加稀土元素，最差的为添加草木灰。

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.
