This thesis is made for ANDRITZ China Technology to find out sludge incineration potential in China. ANDRITZ is looking for markets and customers for ANDRITZ sewage sludge incineration technology in China. In addition ANDRITZ China manufactures centrifuges, skeleton model filter presses, belt presses and rotatory drums to treat the sludge.
Sludge in China has become a major problem. It is considered to be toxic waste, because it contains pathogens, which are dangerous for human health. Therefore the disposal to environment as untreated waste sludge has caused severe damage. China government has stricken sludge disposal regulations in order to protect environment and water resources.
The thesis is divided to wastewater basics, sludge treatment methods, sludge treatment apparatuses, China government vision about sludge treatment and future views. The thesis aims to give information about sludge business, governmental status and supporters. The thesis includes alternative sludge disposal methods and compares them in order to find the best possible situation for sludge incineration in China. There is an estimation the sludge business begins rapidly growing in few years, but sludge incineration is still big question. The best sludge processing methods and answers for future sludge treatments depend on government’s regulations.
Sludge incineration causes air pollution and landfill area scarcity makes it more attractive method to dispose sludge with combustion technology. Landfill as sludge disposal method is causing emission problems to soil and water resources. The Chinese government is responsible for controlling of sludge disposal, which is the most desirable way to protect environment by alternative sludge treatments enforcements.
Furthermore studying sludge energy markets and researching them; this thesis includes a proposal for a patent in China. The patent information and details are not listed or shown in this thesis; the blank area contains secret classified information which hinders a person to read any details.
