Description
Technical field
The present invention relates to a kind of wastewater and waste liquid treatment system, particularly to a kind of waste water triple effect concentrating and treating system.
Background technology
Along with the very big of energy-saving and emission-reduction is paid attention to by the increasing and country of industry and human lives's draining, how to realize
The resource of waste water and waste liquid becomes focus of concern.
It is to utilize physics, chemical and biological method to process waste water that waste water processes, and makes purification of waste water, reduces dirt
Dye, so that reaching waste water reclamation, multiplexing, makes full use of water resource.But the Waste Water Treatment of specialty is to common processing type enterprise
For industry, no matter for the equipment cost of occupied ground and cost, it is all relatively difficult to reach requirement, therefore, causes perhaps
Many industry direct discharging of waste water, not only produce the waste of water resource, but also there is the shortcoming that discharge water is the most up to standard, to environment band
Pollute.
At present, solving the waste discharge problem that above-mentioned middle-size and small-size processing enterprise faces, have two ways, one is by chemistry
The method processed, needs to be reacted by multi-step chemical, therefore often introduces substantial amounts of chemicals and system process is complicated；Two is to pass through
Being carried in cell therefor, the waste water treatment plant of transport to specialty goes process, so can reach the requirement of environmental protection, but this
Sample needs again to solve transportation problem, and substantial amounts of waste liquid, waste water there will be again problem in transport, the most very inconvenient, once reveal
Will result in again the pollution to environment, meanwhile, freight also will increase business processes waste liquid, the cost of waste water.
If after substantial amounts of waste water being concentrated, then the process of waste water process points is delivered in concentrated solution carrying, be thus
Solving above-mentioned problems faced, generally concentrating waste water needs to use vaporizer, and the female of separator so can be by the water in waste water
Separate, discharge or recycle further, but during processing at this, vaporizer heats, after reaching the boiling point of waste water
Evaporating, this will consume the substantial amounts of energy, and the most how reducing energy consumption is the direction that we need to consider.
For above-mentioned phenomenon, patent CN 202529878 U discloses a kind of Waste water concentrating processing system, including vaporizer,
Separator, cooler, concentration liquid bath and connecting pipe road, also include a water-ring vacuum system, and described water-ring vacuum system is main

The mouth of a river is connected with described condensate draining；The present invention is by arranging water-ring vacuum system, it is achieved is evaporated under reduced pressure, reduces the boiling of material
Point, decreases the energy consumption of whole system.
But this Waste water concentrating processing system still suffers from certain shortcoming: (1) shows the vaporizer used, through concentration and evaporation
After gas, gas can be immediately discharged to aerial containing certain impurity, pollute the environment, and then need to by separator again
Separate, but this poor removal effect；(2) this Waste water concentrating processing system, only carries out once concentration evaporation process, thus dense
Contracting evaporation process weak effect；Meanwhile, then the concentrated solution obtained by concentration and evaporation carries out filter pressing process, and concentrated solution typically need to be sent by filter pressing
Process to single pressure filter, system load pressure so can be caused excessive, cause energy loss；(3) after concentration and evaporation
The gas of gained, still containing acid impurities, if directly discharged, polluting the environment in gas, and then by the gas of evaporation gained
Body is emitted into liquid seal trough and carries out fluid-tight, but the gas temperature after evaporation is higher, directly carries out fluid-tight, and fluid-tight effect is bad；Simultaneously
Liquid after fluid-tight can not recycle, and causes the wasting of resources.
