Abstract
The present invention relates to a kind of methods of Combined Treatment industrial emissions, belong to post-processing technology field.Its waste water discharged to bodied ferric sulfate, aluminium polychloride and waste oil recovery process, exhaust gas, noise and immobilized waste carry out Combined Treatment.Independent process bodied ferric sulfate, aluminium polychloride and waste oil recovery process is different from the prior art in the present invention, three kinds of offal treatment techniques are uniformly set in same production district, and the secondary industrial emissions discharged to it are uniformly processed, it is monitored conducive to equipment working condition, cost is reduced, and reduces the pollution to environment.
Description
Technical field
The present invention relates to a kind of methods of Combined Treatment industrial emissions, and in particular to bodied ferric sulfate, aluminium polychloride
With the method for waste oil recovery process Combined Treatment industrial emissions, belong to post-processing technology field.
Background technology
It needs to consume a large amount of raw material and the energy in industrial processes, also be brought while obtaining required product a large amount of
Pollutant.Industrial products are varied, and the industrial waste of generation is also not quite similar, and the waste of industrial output can divide according to form
For solid waste, liquid wastes and gaseous waste are referred to as " three wastes ", its processing method of the waste of different shape is also different.Work
Industry treatment of wastes produced and disposal of commercial waste must also be handled and disposed by the requirement of general waste.Because it gives up with general
Object is quite different in character, so must also consider respective characteristic when processing and disposition.Especially for harmful substance
Processing, it is necessary to strive absolutely reliable.
The processing of industrial waste and disposal of commercial waste must also be handled and disposed by the requirement of general waste.Because
It is quite different in character with general waste, so must also consider respective characteristic when processing and disposition.Especially to "
In the processing of harmful substance, it is necessary to strive absolutely reliable.
Liquid wastes refer to the waste liquid of poisonous and hazardous the harm people and animals and natural environment that are discharged in production process.Waste liquid passes through
The requirement that can be only achieved industrial reuse water and urban water supply after multistep treatment, is generally divided into three-level.Coagulation is pretreatment,
Primarily to removing the floating material and suspended matter in waste liquid and adjusting pH value, BOD, COD etc., to carry out two stage treatment, lead to
The method being often used has tamisage, the precipitation method, floating method and aeration etc..The waste liquid of coagulation is unable to direct reuse or row
It puts.Two stage treatment is that a large amount of organic matters are removed on the basis of coagulation, is traditionally often used activated sludge process and biomembrane
Method just gradually promotes the use of physical-chemical process now with the continuous research and development of chemical reagent especially high molecular material.
Waste liquid after two stage treatment substantially can be with troubleshooting or industrial reuse, if to need to carry out three-level as the supplement of water resource
Processing, therefore tertiary treatment is also referred to as advanced treating or advanced processes.Tertiary treatment is further removal waste liquid（At this time
It is properly termed as processing water）The substance not removed in preceding two-stage treatment, including the undegradable organic matter of microorganism and dissolubility
Phosphorus and nitrogen etc., if also needing to removal poisonous substance, germ and pathogen etc. as domestic water.
Gaseous waste refer to production in discharge it is various to people and animals and the harmful exhaust gas of environment.It can be divided by its composition organic
The industrial waste gas of object and the industrial waste gas of inorganic matter；By the existing forms of nuisance can be divided into harmful exhaust containing solia particle and
Gaseous state harmful exhaust.Pollutant in air is more than a certain concentration, will cause the deterioration of air quality, threaten human body health and
The existence of biology.Industrial waste gas may contain inflammable, explosive low-boiling organic matter, such as aldehyde, ketone, hydrocarbon；There may also be stimulation
The inorganic gas such as property, corrosivity, sulfur dioxide frowzy, nitrogen oxides, chlorine, hydrogen chloride, hydrogen fluoride；Also a large amount of powder
The particulate materials such as dirt, flue gas, acid mist.If gaseous waste without handle or deal with improperly and into National People's Congress's gas, caused by ring
Border influences to be sizable.
Industrial solid wastes refer to the waste residue generated in industrial production, process, dust, clast, sludge and
Barren rock, tailing for being generated in mining process etc..Industrial solid wastes are mainly derived from mining industry, electric power, metallurgy, chemical industry, light industry etc.
Industry, wherein metallurgical solid waste refer mainly to the residue being discharged during various metal smelts, such as slag, blast furnace slag, have coloured gold
Belong to slag, ferroalloy slag etc.；Electric power solid waste includes mainly the flyash and clinker, flue dust that coal burning is discharged
Deng；Other industrial solid wastes include the metal fragment of mechanical processing, leftover pieces, the sawdust etc. of timber processing, grain processing
Waste residue, the body refuse etc. of bone bits, dregs and chemical industry, papermaking etc..
For bodied ferric sulfate, aluminium polychloride and waste oil recycle three kinds of techniques, itself just need processing certain
Industrial emissions, also will appear secondary emission object during recycling, how to secondary emission object carry out Comprehensive Control with
Prevent it from polluting environment, and the cost for reducing enterprise becomes the task of top priority.
Invention content
It is an object of the present invention to overcome the above deficiencies, provides a kind of to bodied ferric sulfate, aluminium polychloride and useless
The method of oily recovery process Combined Treatment industrial emissions, processing mode is reliable, environmentally friendly.
According to technical solution provided by the invention, the method for Combined Treatment industrial emissions, it is characterized in that：Combined Treatment is poly-
The method for closing ferric sulfate, waste water, exhaust gas, noise and the immobilized waste that aluminium polychloride and waste oil recovery process are discharged；Step
It is as follows：
（1）Wastewater treatment：Waste water includes ground flushing water, cooling tower condensed water, acid fog absorption tower waste water, initial rainwater and oil-containing
Sewage；Ground flushing water is that acid waste water is back to production bodied ferric sulfate after being precipitated into wastewater collection pond；Cooling tower is cold
