| titleOfInvention | Method for treating high-concentration ammonia-nitrogen landfill leachate |
| abstract | The invention discloses a method for treating high-concentration ammonia-nitrogen landfill leachate, comprising the following steps of (1) placing an even mixture consisting of clay and river sand in proportion of (5: 1)- (7: 1) in a refuse anaerobic landfill box, adding 1% of denitrifying bacteria, nitrifying bacteria and nitrite bacteria in proportion of 2: 1: 1 into the waste anaerobic landfill box, and adding landfill leachate to be treated to carry out anaerobic treatment; (2) causing the landfill leachate which undergoes the anaerobic treatment to flow into a first collection reservoir and pumping into an SBR (Styrene Butadiene Rubber) aerobic tank by a pump to carry out aerobic treatment, enabling one part of the landfill leachate which undergoes the aerobic treatment to flow back to the landfill anaerobic landfill box after collecting by a second collection reservoir, and putting the other part of the landfill leachate which undergoes the aerobic treatment into a coagulation tank to carry out wastewater treatment; and (3) adding basic aluminum chloride into the wastewater in the coagulation tank to carry out chemical treatment, and then discharging the qualified wastewater. According to the method, stable treatment and qualified discharge can be carried out on the landfill leachate of the refuse landfills. |
