Connection structure of filter material wave tube for saline-alkali land treatment

Abstract

The invention relates to the field of saline-alkali soil treatment, specifically to a filter-material corrugated pipe used for saline-alkali soil treatment and a connecting structure thereof. The filter-material corrugated pipe used for saline-alkali soil treatment comprises corrugated pipes, wherein holes are arranged on each corrugated pipe in uniform distribution; the outer side of each corrugated pipe is provided with a filter screen layer; the interior of each corrugated pipe is provided with a reverse osmosis membrane pipe; each corrugated pipe and each reverse osmosis membrane pipe are connected through a support; micropores are arranged on each reverse osmosis membrane pipe; and a reverse osmosis membrane is arranged on the outer surface and / or the inner surface of each reverse osmosis membrane pipe. The connecting structure of the filter-material corrugated pipe comprises a first connecting mechanism and a second connecting mechanism which are respectively arranged at two ends of the filter-material corrugated pipe. The filter-material corrugated pipe provided by the invention has the advantages of simple structure, convenient operation, low cost, convenient use, and applicability to large-area popularization and application.

Description

Technical field [0001] The invention relates to the field of saline-alkali soil treatment, in particular to a filter material wave tube for saline-alkali soil treatment and its connection structure. Background technique [0002] At present, the area of ​​saline-alkali land is constantly expanding, including arable land, forest land, etc. The area of ​​saline-alkali land in the world is close to 1 billion hectares, and the area of ​​saline-alkali land in China is 100 million hectares, accounting for one-tenth of the world's share; many universities and colleges at home and abroad Research institutes have been studying the treatment of saline-alkali land. Most of the water conservancy engineering methods, biological treatment methods, chemical reagent methods and Chinese scholar Xu Zhikun also proposed in the early 1980s that the order of flushing and drainage should be “first priority then light,” That is, the heavy saline-alkali land is washed first, and then the light saline-alk...

Problems solved by technology

However, these methods have also achieved certain effects on a certain basis, but many technical solutions and construction techniques are relatively lagging behind, and the land resources that need to be developed in my country are relatively slow, and the cost is high, and the effect of salt discharge is not obvious.
