WASTE WATER TREATMENT PLANTS EFFICIENCY IN TEXTILE INDUSTRY
摘要
Water pollution under the influence of the textile industry is becoming a global problem. According to statistical data, 20-25% of wastewater originates from the textile industry. Waste water treatment is carried out to a level that corresponds to emission limit values or to a level that does not violate environmental quality standards. The prevention of deterioration of the water recipients quality is carried out in accordance with the regulations regulating the limit values of pollutants in surface and underground waters, limit values of priority, hazardous and other polluting substances and the regulation regulating the limit values of the emission of pollutants into water, taking stricter criteria than these two. From textile factories, water containing various chemicals for finishing and dyeing fabric is released into waterways. The paper describes the generation of technological waste water in textile industry plants, where dyeing, drying and ironing of final products are carried out, as well as waste water generated after the starching process and after laboratory tests. Also, an assessment of the efficiency of the waste water treatment plant based on the samples quality parameters of technological waste water samples from the textile plant before and after purification is presented.
