Description
Technical field
The utility model relates to acid waste water process for producing field, especially phosphorus-containing wastewater and produces the calcium hydrophosphate fodder device.
Background technology
In the treating processes of existing present high-density phosphorus, fluoric acid wastewater, adopt secondary lime acid-base neutralisation method more.And a large amount of sewage slag that will produce after the processing waste water, and the part addition material as phosphate fertilizer used after sewage slag can only adopt the slag dam heap to fill out or dry at present.
But these methods all do not have and can thoroughly use sewage slag, particularly in the slag contain a large amount of phosphor resources, not only caused the waste of resource, possibly cause simultaneously the pollution of environment.
Summary of the invention
The purpose of this device is the weak point to prior art; Provide a kind of acid waste water that is used for to handle the device of producing calcium hydrophosphate fodder; This device can effectively carry out sedimentation to acidic substance in implementation process; Guarantee that the water outlet quality reaches the requirement of calcium hydrophosphate fodder, the calcium hydrophosphate fodder of its production is up to state standards.
The technical scheme that the utility model adopts: a kind of device of producing calcium hydrophosphate fodder with acid waste water; It is made up of equalizing tank, defluorinate, arsenic reactive tank, high rate settling A, filtering centrifuge A, neutralization reaction groove, high rate settling B, filtering centrifuge B and pipeline; Wherein the inlet of equalizing tank is connected with pond, slag field; The outlet of equalizing tank is communicated with defluorinate, arsenic reactive tank; The inlet of high rate settling A is communicated with through pipeline with the outlet of defluorinate, arsenic reactive tank, and the outlet of high rate settling A connects the neutralization reaction groove, also has pipe connection filtering centrifuge A between said high rate settling A and the neutralization reaction groove; The outlet of neutralization reaction groove is connected with high rate settling B, and the outlet of high rate settling B connects filtering centrifuge B.
All be provided with pH meter and charging opening on above-mentioned defluorinate, arsenic reactive tank and the neutralization reaction groove.
The recyclable utilization of water after above-mentioned filtering centrifuge B filters.
Product after above-mentioned filtering centrifuge B filtration is centrifugal can obtain calcium monophosphate product after the drying machine drying.
The use flow process of this device is: phosphate fertilizer plant's waste water is added in the equalizing tank, add silicon-dioxide and sodium-chlor then, with supernatant liquid adding defluorinate, the arsenic reactive tank of preliminary defluorinate; Add defluorinate, dearsenic agent then, get into high rate settling A and add the flocculation agent sedimentation after reaction is accomplished, the overflow water of high rate settling A joins in the neutralization reaction groove and uses; Simultaneously; Filtering centrifuge A crosses the leaching supernatant liquid and also adds in the neutralization reaction groove, and to wherein adding milk of lime, reaction finishes the back and gets into high rate settling B sedimentation; Last centrifuging, drying obtains product.
The utlity model has following advantage: the Vanadium Pentoxide in FLAKES that adopts this device fully effectively to reclaim in phosphate fertilizer plant's waste water prepares calcium hydrophosphate fodder, improves the utilization ratio of resource; And this apparatus structure is simple, low production cost, and value-added content of product is high, has the stronger market competitiveness, for enterprise brings great economic benefit.
