Description
Technical Field
The invention relates to the field of environmental management, in particular to a sludge harmless treatment system.

The sludge is cohesive soil which is deposited in still water or slow flowing water environment, is formed by biochemical action, has natural water content larger than a liquid limit and has natural pore ratio larger than or equal to 1.5. The modern sediment is formed under the condition of participation of microorganisms, is rich in organic matters, is generally gray black, and has low mechanical strength and strong compressibility. Its shock resistance is poor. Under the action of strong earthquake, the foundation of the building is easy to sink.
The organic pollutants contained in the sludge are not easy to degrade, the toxic residual time is long, and the toxic and harmful substances enter water and soil to cause environmental pollution. Pathogenic microorganisms and parasitic ova in the sludge can enter the sludge after treatment, and the pollution ways of pathogens in the sludge to human or animals comprise direct contact with the sludge, direct contact with the sludge through a food chain, water source pollution by the pathogens, water body pollution after soil pollution by the pathogens, and the like. In the sewage treatment process, 70 to 90 percent of heavy metal elements can be transferred into the sludge through adsorption or precipitation. Some heavy metal elements are mainly derived from industrial discharged wastewater such as cadmium, chromium and the like. In addition, heavy metals are derived from household plumbing systems such as copper, zinc, and the like.
The secondary pollution of the sludge to the environment also comprises pollution of salt of the sludge and pollution of nutrients such as nitrogen, phosphorus and the like. The higher salt content of the sludge can obviously improve the conductivity of the soil, destroy the nutrient balance of plants, inhibit the absorption of the plants to the nutrients and even cause direct damage to plant roots. After a large amount of sludge rich in nitrogen, phosphorus and the like is applied to a soil area with large rainfall and a soil loosening land, when the decomposition speed of organic matters is greater than the absorption speed of plants on nitrogen and phosphorus, nutrients such as nitrogen, phosphorus and the like can enter surface water along with water loss to cause eutrophication of the water, and enter the ground to cause pollution of underground water. Therefore, it is necessary to develop a sludge harmless treatment system.
