Abstract

According to the existing statistical data at the country level, over 65% of the wastewater (rural from agricultural livestock farms) is discharged without purification, 61% are insufficiently purified and only 10-15% are properly purified. The pollution effect of wastewater not purified or insufficiently purified on surface waters, is mainly manifested by the content of suspended matter, of organic matter, in nutritional salts, ammonium and in pathogenic microorganisms. It is well-known that the nutritional salts of nitrogen and phosphorus cause the eutrophication of surface waters, with the effect of consuming the dissolved oxygen needed to sustain the aquatic life. Ammonia is particularly toxic to aquatic life. Unsaturated or insufficiently purified wastewater pollutes groundwater, among others with nitrates, ammonium and bacteriologically. From the presented results, the purification of waste water is an essential requirement of the development of human civilization. Being a necessity with special social and ecological implications, the unitary regulation and the general provision of the necessary infrastructure is a priority, in this sense an article will be presented in an experimental treatment station that performs the collection of waste water from an agrozootechnical farm. The purification of water within this experimental model of treatment plant will be done autonomously from an energy point of view (electricity supply is carried out through a hybrid system based on photovoltaic panels and wind turbine), and the recovery. The use of purified water is done in a greenhouse, using a mixed irrigation system (dripping / spray irrigation).

Highlights

In the current stage of economic and social development, characterized by unprecedented dynamics, on the one hand, and the limited nature of natural resources, on the other hand, water, one of the most important natural resources, must be well managed, for to prevent the "water crisis", a term that appears more and more frequently in the forecasts of international organizations

In order to ensure the sewerage in some situations, the agrozootechnical farm can be connected to the sewerage system of the locality, but in order to achieve this, the water discharged from the farm must comply with the norm of NTPA 002

Summary

Introduction

In the current stage of economic and social development, characterized by unprecedented dynamics, on the one hand, and the limited nature of natural resources, on the other hand, water, one of the most important natural resources, must be well managed, for to prevent the "water crisis", a term that appears more and more frequently in the forecasts of international organizations. At EU level, and in Romania, there are certain regulations that prohibit the placing of livestock farms at short distances from the inhabited areas. In these conditions, it becomes necessary to make some inventions in order to ensure the water and sewage needs. A solution is the relocation of wastewater treatment technologies and the reuse of this water in agriculture
