Qingyan Environmental has developed a set of process technology and equipment suitable for high-concentration organic wastewater such as kitchen waste leachate, livestock and poultry breeding wastewater, and landfill leachate, which have the characteristics of small water volume, high pollutant concentration, high solid and oil content, etc. The technology ensures that the effluent reaches the sewage discharge standard (GBT31962-2015) for urban sewage, and effectively solves the problems of large land area occupied by existing treatment processes, low degree of equipment integration, unstable process operation, and difficult stable compliance with standards.
