Description
Technical field
The present invention relates to the zero-emission of technical field of waste water processing more particularly to a kind of high calcium waste water and resource reusing sides
Method.
Background technique
Larger acid waste water processing is typically all to be neutralized using lime or carbide slag, water outlet in alkalinity,
Calcium concentration reaches 1000mg/L or so, and discharge needs to carry out sour neutralization, and reuse needs to carry out decalcification processing.Traditional decalcification processing
Method be do neutralization medicament with sulfuric acid, sodium carbonate does decalcification medicament.On the basis of the calcium content in waste water, even if according to molar ratio
Sodium carbonate is added in 1:1, and the effect of waste water decalcification is still limited, is discharged calcium concentration many places between 50~100mg/L, total salt quantity base
This is not reduced.More important is the processing cost of this method is higher, is restricted its application range.
Calcium ion in high calcium waste water is difficult to completely remove, existing removal technique cannot all accomplish very to go deliming from
Son, for this purpose, the present invention proposes the zero-emission and resource reusing method of a kind of high calcium waste water.
Summary of the invention

It puts and resource reusing method.
To achieve the goals above, present invention employs following technical solutions:
A kind of zero-emission and resource reusing method of high calcium waste water, include the following steps,
High calcium waste water is discharged into progress preliminary sedimentation filtering in sedimentation basin, determines to shed precipitating reagent in pond to heavy, stir when shedding by S1
It mixes, precipitates the calcium ion in waste water largely, obtain the filtered waste water of preliminary sedimentation；
S2, filtered waste water is discharged into reaction tank again, and multiple rows of adsorption layer is arranged in reaction tank, is filled with life in adsorption layer
Object adsorbent, the biological adsorption agent are made of zeolite, sodium alginate and active carbon particle, and zeolite, sodium alginate and activity
The weight ratio of charcoal particle is 20:3-5:5-8；
S3, then the waste water of primary absorption biological adsorption agent is discharged into clarifier-tank, multiple grid is provided in clarifier-tank, grid
Inner wall be circumferentially provided with adsorption layer identical in S2, biological adsorption agent is filled in adsorption layer；
Purified waste water is finally filtered processing using security personnel's filtering technique, then uses micro-filtrate membrane filtration technique by S4
It is filtered processing, then processing is filtered using ultrafiltration membrance filter technique, the discharge water for meeting environmental protection standard can be obtained.
Preferably, the weight ratio of the zeolite, sodium alginate and active carbon particle is 20:3:8.
Preferably, the weight ratio of the zeolite, sodium alginate and active carbon particle is 20:5:8.
Preferably, security personnel's filtering technique uses cartridge filter, and the micro-filtrate membrane filtration technique uses microfiltration membranes mistake
Filter, the ultrafiltration membrance filter technique use ultrafiltration membrane filter.
Preferably, the grid gap of the multiple grid is gradually reduced.
Compared with prior art, the beneficial effects of the present invention are: being carried out tentatively by the way that high calcium waste water to be discharged into sedimentation basin
Precipitating filtering is determined to shed precipitating reagent in pond, be stirred when shedding to heavy, precipitates the calcium ion in waste water largely, obtains just
Step precipitates filtered waste water, and filtered waste water is discharged into reaction tank again, multiple rows of adsorption layer is arranged in reaction tank, adsorbs
Biological adsorption agent is filled in layer, the calcium ion that can further adsorb in waste water is since biological adsorption agent has service life
It avoids the failure and replacement problem of biological adsorption agent, and devises clarifier-tank, dual absorption, it is ensured that calcium ion adsorbs completely,
The present invention is ingenious in design, and method is reasonable, can accomplish fully absorbing for calcium ion, is suitble to promote the use of.
