Abstract

The problem of wastewater disposal affects not only third countries, but also world giants such as China or the United States of America. The European Union and the Commonwealth of Independent States are no exception. The increasing use of organophosphate pesticides requires the search for new, more efficient and cheaper ways to dispose of their residual amounts. The existing methods of disposal of toxic waste are costly, ineffective, and environmentally hazardous. The optimal solution can be a chemical system for decontamination of wastewater directly at the place of their origin, for example, at the production of pesticide formulations and agro-industrial facilities. This article presents the results of studying the effectiveness of the chemical system for the destruction of organophosphorus compounds based on hydrogen peroxide and potassium hydroxide in relation to dimethoate. The results of the scaling of the decontamination process are presented and an installation for the technological process of wastewater disposal is proposed. The research results show a high reactivity of the system under study and a high efficiency level of the described technological process.

Highlights

  • Food supply is one of the key humanitarian problems

  • The aim of the research is to develop a method for industrial utilization of rinsing water contaminated with pesticides and / or to significantly reduce the volume of utilized waste

  • The existing methods for the disposal of pesticide products have a number of significant disadvantages: the need for large areas of land for polygons, high cost, low efficiency

Summary

Introduction

Food supply is one of the key humanitarian problems. This challenge is faced by the third world countries, and by the world's densely populated giants such as the People's Republic of China and the states of the Arabian Peninsula. The countries of the European Union and the Commonwealth of Independent States were no exception. The food problem primarily concerns the quality of drinking water and primary agricultural products, namely cereals and legumes. Pesticides are used to protect the latter, which are strategically important resources. These substances are used to combat insects, molds, weeds, and other pests
