Drainage and moistening system
The invention relates to the field of agriculture and can find application in the irrigation of small areas due to the accumulation of local runoff and drainage water. Drainage and moistening system contains a drainage network joined with the containment pond 5 of the drainage, the drainage pump station 7 connected through a fine water filter 8 to the network of water distribution pipelines 9 connected to irrigation pipelines 10 with water drip emitters 11. The containment pond 5 is equipped a protective screen 6. Screen 6 is made of a number of panels of lighttight membrane material, one edge of which is mounted on floats of adjacent cables and other quick couplings connected to the adjacent material web. Through the line of quick-disconnect joints, the panels are fastened with bayonet joints in the form of bolts with axial holes and nuts. The system allows to reduce evaporation water losses from the surface of the containment pond and reduce the amount of dead water in it, as well as improve the reliability of the fine water filter.
The chemist of RUDN together with colleagues from Iran and Spain created a catalyst based on palladium and nickel for the oxidation of cyclohesane in the production of adipic acid, which is used for the production of cleaning products, food dyes and other substances. The new catalyst made it possible to double the consumption of cyclohexane.
RUDN University agronomists have proposed a new scheme for fertilizing winter wheat, which allows increasing the yield by 68%. The key to this is in the combination of nitrogen and growth regulators.
RUDN biologists have studied microorganisms that can survive in metalworking fluids. The results will allow “picking up” bacteria and fungi that can process toxic waste fluids into a harmless product.
