Technical solutions for cleaning drainage water from irrigated areas

Abstract

In recent years, there has been an increasing shortage of fresh water suitable for irrigation, which does not subsequently cause soil salinization. To solve the above problem, it is necessary to reconstruct the collector-drainage system into a circulation system. Using the example of open collectors, the dynamics of the chemical composition during the growing season was studied, which showed its dependence on the intensity of irrigation, the salinity of irrigation water, and the seasonal amount of precipitation. A comprehensive assessment of the suitability of water from open collectors for irrigation in terms of salinity, chloride salinity, sodium and magnesium alkalinization and soda formation has been carried out. The necessity of additional treatment of drainage and waste waters to exclude soil salinization has been established. Technical solutions for the purification of the drainage runoff in the stream and with the help of a mobile treatment plant are proposed. A diagram of a removable filter cassette operating in a honeycomb type for water purification in a stream is presented.

Diversity Analysis of Soil Microbial Population Abundance Before and After Planting JunCao "Oasis No. 1" in Saline-Alkali Soil

“…The most signi cant feature of saline-alkali soil is the increase of soil alkalinity, which can lead to the precipitation of soil salts from the inside of the soil and cover the surface of the soil, resulting in the appearance of frosty white soil. At the same time, soil compaction is also accompanied by soil particles condensed into blocks due to the interaction between soil ions, resulting in soil compaction [3] . Soil compaction can seriously damage the soil structure, resulting in the change of soil properties [4] .…”
