Description
Technical field
The invention belongs to technical field of industrial sewage treatment, more particularly, to a kind of trade effluent recovery and treatment method.
Background technique
With the rapid development of economy, the total emission volumn of fluorine-containing industrial wastewater is growing, fluoride pollution is caused to get worse.
Therefore, people start the processing method of positive research fluoride waste, recycle, that is, drop after fluorine-containing waste water is handled
The low pollution to environment, and realize the recycling to resource.But the processing method treatment effect of traditional fluoride waste compared with
Difference, treated, and often there is fluorine ion and sulfate ion residual in waste water, and pollution is equally easily caused after discharge.If lengthening pair
The processing time of fluoride waste increases processing step, then working efficiency is low, and processing cost is high.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides a kind of trade effluent recovery processing side that work efficiency is high
Method.
To achieve the goals above, the invention adopts the following technical scheme: a kind of trade effluent recovery and treatment method, including
Following steps:
(1) industrial wastewater is after flocculation basin and sedimentation basin, by waste water lifting to reaction tank；Add in waste water into reaction tank
Add quick lime, be stirred to react 2-6h, the filtrate A of containing sulfate radicals is obtained after filtering；
(2) white lime is added into filtrate A, is stirred to react 0.5-4h, calcirm-fluoride wet slag and tail washings, tail washings is obtained after filtering
It may be recovered utilization.
Further, the residue being obtained by filtration in the step (1) is calcirm-fluoride wet slag, takes fluoride waste, is given up to fluorine-containing
The calcirm-fluoride is added in water, after being stirred to react 3-5h, calcirm-fluoride and liquor B is obtained by filtration.
Further, calcium sulfate is added in backward liquor B, after being stirred to react 1-3h, gypsum and sulfuric acid are obtained after filtering
Solution.
Further, the input amount of the quick lime is 50-80kg/L.
Further, the input amount of the white lime is 40-70kg/L.
Further, the input amount of the calcirm-fluoride is 45-85kg/L
Further, mud-scraping apparatus is equipped in the sedimentation basin；Solid matter in sedimentation basin is drowned into precipitating bottom of pond portion,
Convenient for reprocessing process in turn to sewage convenient for subsequent except a large amount of solid pollutant in decontaminated water；It is arranged in sedimentation basin and scrapes
Mud device can scrape the mud for sinking to precipitating bottom of pond portion to the center of sedimentation basin, by the spoil disposal pipeline for being set to precipitating bottom of pond portion
By the mud discharge in sedimentation basin, then it is uniformly processed, avoids mud and accumulate in sedimentation basin, cause in sedimentation basin
A large amount of microorganism is bred, avoids aggravating water pollution.
Further, the mud-scraping apparatus includes rotating member, the supporting element being connected with the rotating member and is arranged at intervals at
Multiple on the supporting element scrape mud component；The mud component of scraping includes cleaning shoe and scrapes mud part, and the mud part of scraping connects by one
Relay part is detachably connected with the cleaning shoe；Rotating member and supporting element are set, rotate to drive supporting element by rotating member
It rotates with, scrapes mud component effectively for mud scraped clean to drive；Mud component will be scraped to be arranged to scrape mud part and cleaning shoe,
Cleaning shoe can realize and fix to scraping mud part, can also obstruct the mud swept and cross and scrape mud part and fall into again to original position, set simultaneously
Setting cleaning shoe can also effectively limit flow direction of the mud when being swept, and accumulate mud mutually and towards in sedimentation basin
It is flowed at the heart；And setting scrapes mud part and can scrape the mud of bottom, the mud that will precipitate bottom of pond portion removes；It is Wear-resistant plastic that this, which scrapes mud part,
Material, wearability is good, not easy to wear, therefore long service life, strong to the mud scraping abilities of precipitating bottom of pond portion；And connection is set
Component can be installed convenient for that will scrape mud part to cleaning shoe, scrape mud part convenient for replacing after long-term use, scrape mud part in connecting component
Upper convenient for disassembly and assembly, installation effectiveness is high；Connecting component can also float up and down, therefore have convex block etc. meeting precipitating bottom of pond portion
It, can be effectively to movement, so that ensuring equipment is stable in the case where stuck；Arcwall face will be set on cleaning shoe, therefore scraped
The mud risen can be moved upwards along arcwall face and mud can be fallen to again after movement along the arcwall face
The side that cleaning shoe pushes, and arcwall face setting can shovel the mud of bottom, and original mud of scraping is changed as shovel mud, is scraped
Mud effect is strong；Convex ribs, which are arranged, can reinforce the intensity of cleaning shoe, and the service life that mud is pulled is scraped in extension, and the setting of convex ribs can also reduce
Adhesive capacity of the mud on cleaning shoe, convenient for sending mud to the center of sedimentation basin.
In conclusion the present invention is by the difference of calcium chloride and calcium sulfate solubility product, the fluorine ion in precipitation and separation waste water,
Guarantee that fluorine ion is separated with sulfate ion, and calcirm-fluoride can be obtained；It, can be with sulfate radical by the addition of quick lime/white lime
Reaction obtains gypsum, continues to use in investment sewage treatment, resource utilization is high.
