NOVELTY - Degrading organic chlorine with aerobic bacteria promoting waste water treatment comprises e.g. placing sodium alginate powder in an Erlenmeyer flask, adding distilled water, heating, stirring, dissolving, rising the temperature, adding agar and tryptone, stirring to obtain culture medium, irradiating with 2 Gx of X-ray, sterilizing, adding specific bacterial suspension, injecting potassium chloride solution, domesticating the culture, placing in freezing chamber, curing, washing, irradiating with 2 Gx of X-ray, placing in wastewater containing organic chlorine and treating.    USE - The method is useful for treating wastewater by degrading organic chlorine with aerobic bacteria (claimed).    ADVANTAGE - The method increases the degradation of organic chlorine, avoids microbial poisoning and overcome loss of activity.    DETAILED DESCRIPTION - Degrading organic chlorine with aerobic bacteria promoting waste water treatment comprises (i) placing 5-10 g sodium alginate powder in an Erlenmeyer flask, adding 30-80 ml of distilled water, heating to the temperature of 35-45 degrees C and stirring with glass rod for stirring for 10-15 minutes, (ii) dissolving, rising the temperature to 45-60 degrees C, adding 1-5 g agar and 20-50 ml tryptone into the Erlenmeyer flask, starting the electric mixer and stirring with electric mixer for 8-12 minutes to obtain culture medium, (iii) irradiating the obtained medium with 2 Gx of X-ray for 15-25 minutes and sterilizing, (iv) adding specific bacterial suspension into the medium under sterile conditions, injecting 30-50 ml potassium chloride solution every 30 minutes and domesticating the culture at temperature of 35-40 degrees C at pH 7-8 repeatedly under illumination for 10-20 hours, (v) placing the domesticated trained aerobic bacteria in freezing chamber, curing for 1-2 hours, washing with sterile water for 1-2 times, irradiating with 2 Gx of X-ray to obtain specific culture of aerobic bacteria, and (iv) placing the trained aerobic bacteria as filler in wastewater containing organic chlorine in the ratio 1:600-1200 and treating for 3-6 hours.
