Comprehensive Utilization of Sludge from Urban Sewage Treatment Plants
(1) Utilization of sludge in agriculture and forestry
Various organic matter and growth elements in municipal sludge are a very good fertilizer and improver. We can use sludge to grow flowers and lawns without polluting food production and reducing dependence on chemical fertilizers.
(2) Utilization of building materials
Some urban sewage plants cooperate with cement product factories or anvil factories to incinerate sludge together as admixtures, and finally produce building materials that meet the quality standards, such as bricks, ecological cement, ceramsite, fillers, etc.
(3) Other comprehensive utilization
Some urban sewage plants cooperate with heating and power generation units to use dehydrated sludge instead of part of coal, and achieve good efficiency. Sludge can be disposed of harmlessly during incineration, and the cost of heating production is also reduced.
In short, the sludge treatment and disposal of urban sewage plants adopts the disposal principles of “reduction, stabilization, harmlessness, and recycling” and adopts the method of comprehensive utilization. In this way, we can solve the problem of environmental pollution and at the same time achieve good results economic and social benefits.
