Abstract
A kind of incineration of refuse flyash wastewater zero discharge and recycling unit and treatment process, the technique include four most of ten steps:Pretreatment, the concentration of Multistage Membranes sub-prime, film and sub-prime crystallize four parts.Equipment is mainly formed by connecting by incineration of refuse flyash wastewater equalization pond, heavy metal desorption apparatus, film softening plant, sludge dehydration device, cationic switch, multi-stage separation film device, chemically-cleaning device, scale inhibitor feeding device, regenerative agent throwing device, regenerating unit, hyperconcetration device, electrodialysis plant, sub-prime crystallization apparatus, mother liquor solidification equipment and auxiliary device through pipeline.It is an advantage of the invention that for generated waste water during incineration treatment of garbage, pass through the combination of multiple water treatment technique, realize wastewater zero discharge, the fully salinities such as recycling sodium chloride, potassium sulfate, and the valuable heavy metal such as efficiently separate copper, zinc is for centralized recovery, system operation cost and operation risk are reduced, economic benefit is obtained.
Description
Technical field
The present invention relates to a kind of environment protection equipment and treatment process, more particularly to a kind of incineration of refuse flyash waste water zero-emission
It puts and recycling unit and treatment process.
Background technology
In garbage incinerating power plant operation, the generation of landfill leachate is to receive the environmentally friendly hot spot of common concern at present,
Its processing also receives increasing attention.In addition to landfill leachate, flying ash waste water is equally urgently administered, such waste water usually has
The features such as capacity is big, suspension content is high, salt content is high, hardness is high, content of beary metal is high.Treatment process can only will suspend at present
Object, salinity, heavy metal all cure, and become dangerous waste, and disposal costs are expensive.How " heavy metal ", " salt recycled from this strand of waste water
Point " and " water " three substance, realize that zero-emission and recycling are the important of urgency problem to be resolved and sustainable stable development
Link.
Not only salt content is high for flying ash waste water, and salinity composition is complicated, maximum rich in potassium, sodium, chlorine root, sulfate radical etc.
Degree isolates the valuable salinity tool such as sodium chloride, potassium sulfate and acquires a certain degree of difficulty.In addition, also containing in flying ash waste water higher
The heavy metal of concentration, stringent limitation of the substance by national wastewater discharge standard, it is necessary to effectively remove.If but with precipitation form
Removal then becomes dangerous waste, and processing economy can just be highlighted by recycling heavy metal to greatest extent.
Currently, being directed to dense salt wastewater minimisation reuse both at home and abroad until the method for zero-emission is numerous such as reverse osmosis, just oozes
Thoroughly, electrodialysis, membrane distillation, evaporative crystallization etc., but be applied to flying ash wastewater zero discharge and recycling have it is certain
