Řešení problematiky biologického oživení odpadních vod Lovochemie a.s.

Abstract

Diploma work is engage in specification of occurrence reason and recommendation for solving a problem with biological activation of waste water with Sphaerotilus natans. Work contains analysis of problem from technological point of view and influence of physical and chemical stimulation. Key parameters are mainly oxygen content in tail water – course, pH of waste water and origin of waste water incoming to sewage treatment. Final part contains recommendation for solving this problem.

On base of monitoring occurrence of organism and producing of production units of Lovochemie, wasn´t found any connection between producing waste water from units and presence of organism. Production conditions haven´t essential influence on presence of Sphaerotilus natans in outlet of waste water to river Labe. In contrary, essential influence on this problem have chemical and technological properties of waste water. Alkaline pH and low level of waste water is main reason of occurrence Sphaerotilus natans. As a likeliest solution of reduction of biological activation of waste water is permanent decrease of pH value of waste water and replace of concrete tail water – course.
