Degreasing 150L is removed in steady room, the step；
2nd, break steady room carries out broken steady process to waste liquid, with destroying waste liquid and stability, and will it is broken it is steady after waste liquid send into and flocculate
Device；
3rd, flocculation plant carries out liquid waste processing to waste liquid, adds 13kgPAC and 11kgPAJ as flocculant, and stir toward waste liquid
After mixing reaction 20min, flocculate and liquid are obtained；To liquid measure, in waste liquid, bichromate reduces 73%, then by waste liquid
Send into defecator；
4th, defecator is filtered to waste liquid, and flocculate is sent into mixing storeroom, and liquid sends into reactor；
5th, the hypochlorite of 90mg is added in a kettle., is irradiated and after stirring reaction 30min, to which in being placed in Burdick lamp
Measure, the bichromate in waste liquid reduces 81.3% on the basis of before, and liquid is sent into electrolysis unit then；
6th, electrolysis unit adopt Fe/C micro-electrolysis methods, Fe/C volume ratios be 1.5, ferrum Resina Draconis degree be 60-80 mesh, ammonium chloride dosage
For 1850mg, Jing after with Fe/C light electrolysis, liquid chroma removal rate 95%, bichromate is reduced on the basis of previous step
58%, liquid is sent into into reverse osmosis unit then, the impurity adsorbed on electrolysis unit electrode sends into mixing storeroom；
7th, the water in liquid can be appeared, water with pressure as motive force by reverse osmosis unit by means of the skill of permselectivity membrane
In impurity, such as ion, Organic substance etc. are trapped within the influent side of film, then directly discharge the water for appearing, containing impurity
Water sends into mixing storeroom.Finally, process complete can qualified discharge water be 1.8L, the material accounting not directly discharged is very
It is little.
The 8th, the 500L mixture of repeatedly accumulation storage is sent into the reaction in negative pressure of vacuum dewatering system from mixing storeroom
Kettle, vacuum pump are evacuated to reactor, and the atmospheric pressure in reactor is changed into 0.5 atmospheric pressure, and then reactor is in which
Mixture heating, when being heated to 50 DEG C, the moisture in mixture be changed into vapor from condenser flow out；Mixture is deviate from
After processing 20min, moisture is had been processed substantially, and mixture forms caking because of dehydration, and caking is sent into pulverizer, caking then
Gross weight be 300kg；
9th, the caking sent is ground into powder by pulverizer, and sends into combustor；
10th, the greasy dirt processed out in underground work liquid waste treatment system is sent into into combustor from greasy dirt storeroom, as combustion adjuvant
Use, while air pump provides sufficient air for combustor, be easy to what is burnt to be smoothed out；Ashes and cigarette are formed after dust-firing
Dirt, and certain moisture is carried, ashes and flue dust are sent into into rotary drier；
11st, rotary drier is dried to the product after clod burning, is sent to discharge chamber after the completion of being dried；
12nd, discharge chamber carries out discharging to the material sent, and ashes are sent into storage ashpit, and flue dust sends into the rotation in air treatment system

13rd, the solid particle and gas in flue dust is separated by cyclone separator by centrifugal force, solid particle is sent into and is store
Ashpit, feeds gas into air purifier；According to measurement, show that the 500L mixture is produced Jing after processing, burn in flue dust
Solid particle weight be 0.5kg, by cyclone separator, not only the solid in flue dust can be collected, be easy to follow-up
Process, also add the service life of air purifier, without be replaced as frequently as or scavenging air depurator the correlation such as filter element
Device；
14th, air purifier is purified to the gas sent, and adsorbs the material for being not easy to direct discharge in gas, then
Gas is discharged in air；
15th, the mixture for storing the solid particle of the ashes and cyclone separator of ashpit self-discharging in future room is sent into into composition detection dress
Put, the material for being not easy to discharge of environment in component detection apparatus detection mixture, whether is polluted containing heavy metal etc.；After testing,
There are the heavy metals such as chromium, copper in mixture, it is impossible to directly discharge, therefore mixture is sent into into brickmaking machine.Jing is measured, 500L mixture
Ultimately form the ashes of 300kg.Although the material containing heavy metal is although harmful, and it is then to make use of weight by its brickmaking
Standard of the dissolution of metal less than Environmental Protection Administration, therefore the products such as harmless haydite, water-permeable brick can be manufactured.
Above-described specific embodiment, has been carried out further to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail, the be should be understood that specific embodiment that the foregoing is only the present invention is not intended to limit the present invention
