Use of Pistia Stratiotes (Araceae) in Water Quality Management in Khorezm Region (Uzbekistan)

Abstract

In this article there is described about Khorezm region conditions Pistia water cabbage (Pistia stratiotes)scientific and practical significance and methods of plant biology, reproduction in biological pools and their use in biological treatment of waste water. The results of the study are mentioned. Research work was carried out In flowing water of the effluent from the Khiva Carpetplant in Khiva, based on the cultivation of the pistiya plant. When studying the physicochemical composition of wastewater in the mouth, the temperature of the experimental water rose from 27.50C to 33.80C, the water (Ph) medium increased from acidic to alkaline (6.8-7.6), the color changed from reddish-yellow to colorless, the odor disappeared. , decreased amount of suspended solids (107.5-72.5 mg / l), increased amount of oxygen (1.4-12.3 mg / l), decreased amount of KBS5 (123.5-28.7 mg / l), During the oxidation process, the amount of O2 decreased from 118.4 mg / l to 28.9 mg / l and the amount of ammonia to 9.0-1.8 mg / l, as well as the loss of nitrites, nitrates and sulfates 121.0-67.0 mg / l, chlorides 113.0-54.8 mg / l, phosphates 8.3-1.4 mg / land it was determined that this water could be reused.
