Study on practical methods for treatment of oil-contaminated and domestic wastewater

Abstract

The implementation by small innovative enterprises of the LBR technology for household wastewater treatment, which is a complete cycle of urban wastewater treatment (WWTP), is one of the most perspective direction of strategic development of the regional economy, improving the parameters of its investment, environmental and social components. Each technological stage of technology is carried out on separate devices located indoors - a technological process of a closed hardware type. Such a process lends itself to automation, since each of the devices is technologically autonomous and can be replaced by another due to a malfunction or according to technological indications. In this way, high process stability and flexibility are achieved. All devices are of serial factory manufacturing, which ensures high quality, aesthetics and reasonable price parameters, as well as, if necessary, the ability to upgrade each unit individually. The hardware type of the technological process, being high-tech, energy-efficient and environmentally friendly, creates the prerequisites for a significant reduction in sanitary protection zones (2–6 times) and areas allocated directly to sewage treatment plants (7– 8 times). In addition, it becomes possible to flexibly change the capacity of WWTP (increase or decrease if necessary), as well as introduce purification stages necessary for specific conditions or remove unnecessary ones, without compromising the integrity of the technology and the efficiency of wastewater treatment. Implementation LBR technology by small innovative enterprises maximum environmental, social and economic efficiency and at prevent the waste of investment resources.
