Original abstract
The contribution is devoted to the design of a sewage sludge disintegration unit with the capacity of 10.8 t/d of a liquid sludge (refers to a wastewater treatment plant capacity of 10,000 population equivalents). Used material properties and insights have been gained in experimental work. Based on measured data, a pressure vessel was proposed. Further, stress analysis, considerations concerning the vessel heating and an economical evaluation of the process was elaborated. In the evaluation, a payback period of approx. 15 y is determined, which emerges from the savings in sludge disposal.
Czech abstract
V příspěvku je prezentován návrh desintegrační jednotky určené pro ČOV s kapacitou cca 10 000 EO, což představuje hmotnostní tok cca 10,8 t/d vyhnilého kalu. Návrh jednotky vychází z předchozích experimentální prací. Jelikož je reakční nádoba koncipována jako tlaková, byla provedena i pevnostní analýla. Součástí příspěvku je rovněž ekonomické zhodnocení realizace navržené desintegrace kalu, které ukazuje, že za současných podmínek je doba návratnosti 15 let, což téměř převyšuje životnost techologie.
