残膜污染治理回收技术研究

A Study on the Treatment and Recycling of the Used Plastic Film

我国的地膜覆盖栽培技术从20世纪70年代未开始示范推广,目前,已广泛应用于蔬菜、棉花、小麦、玉米、马铃薯及甜菜等多种作物。由于塑料残膜难以降解,若不得以及时有效回收,就会对农田和生态环境造成严重影响,带来"白色污染"。从农膜生产、投入使用到清理回收和再生利用等多个环节,进行全方位地残膜污染治理回收技术研究,并提出加快发展残膜治理回收技术的建议。

The plastic covering farming technology began at the end of the 70s of the twentieth Century and is now widely used in the growing of vegetables, cotton, wheat and corn, etc. Due the difficulty in the degradation of the used plastic film, great damage will be done to the farm land and our ecologic environment by the ＂white pollution＂ if the used plastic film is not retrieved in time. This paper aims to study the technology of treating and retrieving the used plastic film in the whole process from its production, application to its retrieving and recycling. Some proposals have been put forward in terms of speeding up the development of the used plastic film retrieving technology.
