Treatment and disposal of residual sludge from biological treatment of dyeing wastewater

Biological treatment of wastewater from dyehouse will produce a lot of sludge. This paper systematically introduced treating and disposal methods for residual sludge and their advantages and disadvantages. Disposal methods include land use, incineration and sanitary landfill. Recent developed treatments include wet air oxidation, ultrasonic wave technology, highspeed bioreactor and mined area filling. The following processes can reduce the sludge production, such as membrane bioreactor, ozonization, micro organism predation, as well as hydrolysis and acidification process.
