The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As illustrated, a kind of processing system of machining cleaning waste water of the present invention, including wastewater disposal basin 1, in addition to according to
The precipitation process pond 2 of secondary connection, hydrolysis acidification pool 3, contact-oxidation pool 4, secondary precipitation processing pond 5, filtering ponds 6, reverse osmosis membrane
Unit 7 and low temperature crystallization evaporator 8；The filtering ponds 6 include the first filtering ponds 61 and the second filtering ponds 62, first filtering
Quartz filter 9 and active carbon filter 10 are disposed with pond 61, ultrafiltration membrance filter is provided with the second filtering ponds 62
Device 11.
Further, the quartz filter 9 includes framework 91, and quartz sand 92, institute are provided with the framework 91
Stating the particle diameter of quartz sand, particle diameter distributes step by step from top to bottom, from the coarse to fine.Increase the retaining power of quartz filter 9, produce water
Ability is big, and impurity penetrates depth, and the rate of filtration is improved on the premise of effluent quality is ensured, mainly go water removal in suspension,
Colloid, organic matter.Meanwhile active carbon filter 10 uses and the identical structure of quartz filter 9.
Further, second filtering ponds 62 include pond body 63, and described cross in the two lateral walls of pond body 63 is provided with
Bar groove 64, the both sides of ultrafiltration membrane filter 11 are provided with the card article 12 for stretching into bar groove, set on the ultrafiltration membrane filter 11
It is equipped with handle 13.By card article 12 and bar groove 64, ultrafiltration membrane filter 11 can be dismantled easily out of second filtering ponds 62, from
And conveniently clean and change.
Further, the ultrafiltration membrane filter 11 includes the first frame 14 and the second frame 15, first frame 14 and
Milipore filter 16 is installed, first frame 14 is connected with the second frame 15 by screw 17 between two frames 15.
Further, the secondary precipitation processing pond 5 includes dosing pond 51 and sedimentation basin 52, is set in the dosing pond 51
Agitating device 53 is equipped with, the bottom of sedimentation basin 52 is taper, and sediment outlet 54 is provided with the bottom.Filled by stirring
53 are put, waste water is quickly combined with flocculant, is precipitated into sedimentation basin 52.
Further, it is provided with baffle plate 55 in the sedimentation basin 52.Waste water produces shock with baffle plate 55, accelerates precipitation.
Further, air flotation slot 18 is additionally provided between precipitation process pond 2 and hydrolysis acidification pool 3.
The technological process of the processing system processing waste water of the present invention is as follows：
Waste water in wastewater disposal basin 1 enters precipitation process pond 2, and coagulant is added in precipitation process pond 2 so that caused outstanding after oxidation
Floating molecule condenses together, while adds sodium hydroxide and sulfuric acid regulation wastewater pH, and the pH for keeping waste water is neutrality；Again plus
Entering a certain amount of flocculant PAM makes particulate matter further polymerize the flco as larger particles, staticly settles.Coagulated particles thing sinks
Form sediment to bottom land, filter-press dehydration processing, mud cake outward transport are carried out after sludge shifting pump squeezes into sludge concentration tank.Precipitation water outlet enters gas
Floating trough 18, the micro-bubble of high degree of dispersion is formed in the reclaimed water of air flotation slot 18, adhere to the solid or liquid of hydrophobic group in waste water
Grain, water-gas-particle three-phase mixed system is formed, after particle adheres to bubble, form apparent density and be less than the flco of water and float to
The water surface, form scum layer and be stripped off, so as to realize the process of solid-liquid or Liquid liquid Separation.
Waste water after separation enters hydrolysis acidification pool 3, and hydrolysis acidification is outstanding by the antirust agent of the residual in sewage, complexant etc.
Floating pollutant and dissolved organic matter are hydrolyzed to organic acid, larger molecular organicses is decomposed into small organic molecule, insoluble
Organic matter changes into dissolved organic matter, when these products through anaerobic hydrolysis, which enter Aerobic Pond, carries out Aerobic Process for Treatment, improves
The biodegradability of sewage, improve the efficiency of oxygen；
In catalytic oxidation groove 4, biological metabolism is carried out in the presence of oxygen with degradation of organic substances, stabilizes it, is harmless
The processing method of change.Microorganism is that substrate carries out aerobic metabolism using organic pollution present in water, by a series of life
Change reaction, the organic pollution and other impurities significantly gone in water removal.Secondary precipitation processing pond 5 will produce in biochemical reaction process
Raw biological sludge flco is collected and precipitated.
Waste water after separation enters filtering ponds 6, sand filtration and active carbon filtration from different specific weight and the filtrate of particle diameter, filtrate
For quartz sand and activated carbon, particle diameter distributes step by step from top to bottom, increases the retaining power of filter layer, water-yielding capacity is big, and impurity is worn
It is thoroughly deep, the rate of filtration is improved on the premise of effluent quality is ensured, suspension, colloid, the organic matter mainly gone in water removal, is made
Pretreatment water outlet reaches RO inflow requirements, and supernatant flows automatically to rear end, and being pumped into self-cleaning filter by relaying enters a filtering
Remove the tiny particles content retained in water.Part residual organic matter is removed by the suction-operated of activated carbon, makes filtering water outlet
Meet into film requirement.Then ultrafiltration membrance filter is used, available for suspended particulates, colloid, microorganism gone in water removal etc..In hydraulic pressure
In the presence of hydrone and small-molecule substance pass through milipore filter, suspended particulates, colloid, microorganism in water etc. are then trapped within super
The inner surface of filter membrane.Due to the micropore very little on milipore filter, can effectively remove suspended particulate in various water, colloid, bacterium and
Larger molecular organicses etc..
Waste water after filtering enters reverse osmosis membrane unit 7, is completely removed Organic substance in water, and removes most of salinity,
Factory's recycle-water requirement can be fully achieved in reverse osmosis membrane water outlet.Concentrated water by reverse osmosis membrane unit 7 is finally by low temperature crystallization
Evaporator 8 is transported outward after concentrating.
Indices before wastewater treatment are：pH：10-12；COD（mg/L）：400-500；SS（mg/L）：200-300；
LAS（mg/L）：15-25；Ammonia nitrogen（mg/L）：30-40；Electrical conductivity（us/cm）：2500；Petroleum-type（mg/L）：40-50.By this
After the processing system processing of invention, pH：7-8；COD（mg/L）：≤30；SS（mg/L）：≤5；LAS（mg/L）：≤0.1；Ammonia nitrogen
（mg/L）：≤0.1；Electrical conductivity（us/cm）：≤200；Petroleum-type（mg/L）：≤0.1.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
