IMPROVED PROCESS AND EQUIPMENT FOR PURIFYING TREATMENT AND UTILIZATION OF WASTE-WATERS FROM THE DAIRY INDUSTRY

摘要

Process for the purifying treatment of waste-waters from the dairy industry through the coagulation of the fat and protein content by treatment with chemicals and through the removal, in given case through the re-processing of economic utilization purpose of the forming waste sludge as well as an equipment for the effectuation of the process. The essence of the process consists in that the waste-water is destabilized for a definitive time in presence of a suitable bacterial flora be­tween the formation and the chemical treatment and the destabilization is accelerated expediently by measures augmen­ting the contacting surface, in given case increasing the intensity of the contacting. The forming waste sludge or its solid content can be utilized by being burnt in furnace, being added to fodder or my ameliorating fertilization. The pre-purified waste-water can be advantageously after-purified by additionally applying an aero-biological (active-sludge) procedural phase.
