通过对中美两国城市工业废弃地污染治理的比较研究，认为中国对城市工业废弃地污染治理的重视程度低于城市大气污染、水污染的治理，存在相关法律法规不完善、污染责任认定不明晰、治理资金缺乏、风险等级评估不科学、公众与社区参与意识不强、治理方法与技术落后、污染信息不透明、治理后用途单一等问题，对此提出了相应的改进建议。

At present, film photocatalytic is studied mostly for treating with water pollution. Because the film will not bring the secondary pollution, and can be used again. ZnO film and TiO_2 film is mostly used as photocatalyzer, but they have some disadvantage, as they can only absorb little of the sun-light energy, the photoluminescence exciton compounds mostly, and they can be eroded easily by light. Complex semiconductor film is a good method to ravel out these problems.
