Abstract
The article presents the studies of a sorption-mechanical filter with a combined loading of zeolite and activated charcoal. As a result of the study, the sorption properties of this load in relation to the chemical elements in the wastewater were studied. The experiment showed that the optimal filtration time was 12 hours, and during the chemical analysis, data were obtained on reducing the concentration of impurities to the maximum permissible. Therefore, the use of sewage sludge makes it possible to use it as fertilizer. We propose the introduction of mineral fertilizers (activated sludge) with irrigation water on irrigated crop rotation areas using sprinkler irrigation. The implementation of the above measures will make it possible, with great economic effect, to completely utilize the sludge from the treatment facilities of agricultural enterprises as fertilizer, which indicates great opportunities to use this method of treatment in the national economy.
Highlights
One of the topical issues is the search for cost-effective, improved methods of wastewater treatment, as well as new technological schemes for the treatment and disposal of sludge
On the basis of the studies carried out, in order to simplify and reduce the cost of the technological scheme of wastewater treatment, it is proposed to use a sorption-mechanical filter with a combined loading of natural zeolite and activated charcoal
Filtration time is 12 hours; the absorption percentage of all chemical impurities is over 90%
Summary
One of the topical issues is the search for cost-effective, improved methods of wastewater treatment, as well as new technological schemes for the treatment and disposal of sludge. Many agricultural enterprises, such as poultry farms, pig farms, and cattle farms, do not have proper treatment of animal waste. Sorption-mechanical wastewater treatment with the use of various sorbents is gaining momentum. Environmentally friendly, natural origin, and durable sorbents are selected as loading. There are a very large number of natural sorbents around the world, and every research scientists find more and more effective and durable materials for loading sorption filters. The most famous and already proven ones are such natural absorbers as zeolite, vermiculite, activated charcoal, analcime, brucite, and so on [2, 3, 4, 5]
