Abstract
One of the complex and urgent geoecological problems requiring timely solution is the accumulation of industrial and household waste in the aquatic environment, that is, wastewater from cities and industrial facilities requiring safe disposal. This problem is closely related to hydroecological rationing, on the basis of which the parameters of the state, the intervals of their natural fluctuations are determined, the identification of threshold and critical values of parameters that ensure the preservation of the portrait of natural systems.
Analysis of wastewater discharged by cities and industrial enterprises of the republic shows that most of them are quite suitable for irrigation of agricultural crops in terms of the content of polluting ingredients.
The practice of farms has shown that the design of irrigation systems using wastewater is a very profitable and promising direction, both in environmental and economic terms. Wastewater is rich in substances useful for plants. Experts have estimated that 60% of all wastewater in our cities is equivalent to 200 million tons of manure in its fertilizing properties. Annually, Kazakhstan discharges normatively clean and biologically treated wastewater only in cities up to 1.5 billion m3/year, which at an irrigation rate of 5000 m3/ha can water 30,000 hectares of land.
In the article, the state of wastewater disposal systems is considered as a factor of environmental safety and sustainability of the natural complex. Solving the problem of preventing the negative impact of wastewater disposal systems on the environment and eliminating a number of environmental problems is directly related to the need to retechnologize most sewage treatment plants built in the middle or second third of the last century.
