Abstract
This article proposes a solution to the urgent problem of treating oil-, fat-containing wastewater. A phase separator of dispersions for preliminary purification of industrial wastewater contaminated with fats is proposed, its effectiveness in the treatment of wastewater at local treatment facilities of an industrial plant for the production of sunflower oil is tested. In order to reduce the cost of acquiring reagents and increase the efficiency of purification of fat-containing wastewater, the use of carbide sludge and sodium hydroaluminate was studied. Laboratory studies conducted by the method of an active experiment.
Highlights
In the framework of import substitution, the issue of treating industrial wastewater (IWW) and waste disposal is more relevant
During the treatment of fat-containing wastewater, the phase dispersion separator (PDS) was located in the local treatment facilities of enterprises (LTF) industrial building of the industrial enterprise
To improve the quality of treated water to the levels established by regulatory documents and to reduce costs, retechnologization of treatment plants using the physicochemical scheme of wastewater treatment has been carried out
Summary
In the framework of import substitution, the issue of treating industrial wastewater (IWW) and waste disposal is more relevant. The deteriorating environmental situation is forcing stricter requirements for the discharge of waste and wastewater from enterprises (Table 1). The maximum allowable Unit of value of the indicator and measurement (or) concentration in a natural wastewater sample un.
