Decontamination of Sewage Sludge Using Lime Materials
Keywords:
sludge, lime, decontaminationAbstract
In recent years, built and entered into operation a large number of treatment plants for waste water. In biological purification, there are large of sludge. Due to insufficient decontamination and stabilization limited their implementation in practice, as required by law. A study on the use of lime as a means of disinfection and stabilization of sewage sludge Plovdiv. Tested are different rates of treatment with lime - 15, 20 and 30% „quicklime of the dry matter of the sludge. It was found that 20% of sludge treatment with fine lime is obtained sludge decontamination effect can be utilized in practice.
