PHYTOSTIMULATOR FROM THE WASTE OF CULTIVATION OF THE BLACK SOLDIER FLY

, , , ,
 95-105 p.
Abstract
The main chemical and sanitary indicators of waste formed during the cultivation of the fly Hermetia illucens were determined. The compliance of chemical and sanitary indicators with the requirements for waste for their use in agriculture is shown. Various methods for preparing a phytostimulator have been tested, the simplest and most effective method has been chosen - with the help of aqueous extraction. Proposed method allows to develop non-waste technology for production of biologically active substances. Based on data on the productivity of the growing process, phenological features of the development of primarily cereal and oilseeds after treatment with a phytostimulator, it can be concluded that it is advisable to use a phytostimulator obtained from Hermetia illucens fly cultivation waste.

ANALYSIS OF THE CHEMICAL COMPOSITION OF PRODUCED WATER

,
 5-14 p.
Abstract
Chemical composition and amount of produced water microorganisms of offshore oil production were investigated. An excess of the content of a number of chemicals was found. The most significant deviation is the excess of chemical oxygen demand (COD). The change in chromaticity, the presence of a specific odor and qualitative reactions to the presence of aromatic hydrocarbons indicate the presence of dissolved petroleum hydrocarbons in water. Hydrocarbons contained in reservoir waters are very toxic. Their acute toxicity for Daphnia magna was shown. In order to prevent harmful effects on the ecosystem of wastewater of this type, it is proposed to use a sorp-tion treatment method.
