Fluidized bed incineration furnace (FBF) on the process performance is concerned, proved to be the best way in the burning of sludge (turbulent way, postbustion of up to 850 degree temperature). And it runs reliably (in the oven without turning section). In 40 years time, Vivendi has built a worldwide dozens of fluidized bed incinerator (such as the European Union, Russia, Turkey). Typically, in a stable state does not require adding extra fuel, the continuity of heat balance can be achieved. If the calorific value of sludge LCV is too low (such as low volatile solids, and / or solid content), exhaust / gas heat exchanger should be large enough to increase the wind room temperature. If you fail (such as extended aeration sludge containing 20% DS), you need to in front of heating and drying. On the dry ash disposal, industrial pollution is not purely for the municipal sludge, heavy metals, not a problem. Because gray is the form of oxides, their permeability is not strong, so it can be reused as cement, used for industrial and road construction. The final step acid byproduct is removed. As the heavy metal pollution, they can only be buried in a special place, but in small quantities. Coincineration of municipal solid waste. In order to reduce investment, urban waste and municipal sewage sludge is usually a burning furnace. Typically, a population equivalent of daily production of 150 to 250 grams of dehydrated viscous sludge and 1 ~ 3 kg of garbage. According to the design of incinerators, can be 10 ~ 25% (soil / litter) and viscous sludge to control the temperature of the stove. In order to achieve optimum bustion, and is not due to unbrunt organic sludge contaminated clinker can be used as a processing capacity 1m3 / h of PyromixTM equipment, through the pressed air to turn into a drop of sludgelike mud. In fact, this method only if the wastewater treatment plant is running away from the municipal solid waste incinerator close when the benefit, otherwise the cost of transportation will be high. Sludge in the system at this time only when necessary to use as the control flow. Wet air oxidation. Vivendi Water Systems R amp。s requirements, need to be considered is that the process to be able to protect the environment, the benefit of people, to be able to optimize the material and energy recycling to achieve sustainable development purpose.
