Information

Sludge is almost always produced in an industrial Wastewater treatment system. If these sludges are not treated, the direct discharge will cause a certain degree of pollution to the surrounding environment and local soil.

Best Wastewater treatment from China manufacturer
There are many types of sludge produced by wastewater treatment, including heavy metals or hazardous chemical substances, etc.; the sludge produced in wastewater treatment should be handed over to qualified units for sludge treatment. Sludge treatment qualified units should mainly have the "Hazardous Waste Business License" or "Environmental Pollution Control Facilities Operation Qualification Certificate".
At present, most of the domestic sludge disposal methods are incineration, sanitary landfill, composting, drying and granulation, and throwing into the sea.
Wastewater treatment manufacturers tell you that incineration is the use of abundant biomass in sludge to generate heat. During the incineration process, all bacterial pathogens will be completely killed at high temperature and the toxic and harmful organic participants in the sludge will be thermally oxidized and decomposed . Incineration ash can be used as a raw material for cement production. Heavy metals are fixed in concrete to prevent heavy metals from polluting the environment again.
Wastewater treatment manufacturers tell you that sanitary landfill is the main method to deal with municipal waste at this stage; it is to transport the dehydrated sludge to the landfill to be treated with the municipal waste at the stage, and to treat the sewage according to the process of solid waste treatment in the sanitary landfill. Mud is processed.
Wastewater treatment manufacturers tell you that sludge drying and granulation is an emerging treatment method in recent years. The mud granules after drying and granulation can be used as fertilizer, soil conditioner and fuel, etc.
Wastewater treatment manufacturers tell you that the treatment of sludge into the sea has become less and less. For the protection of water resources, most of the sludge treatment methods at this stage are mature and non-polluting incineration technology.
