Description
Technical field
The present invention relates to a kind of wastewater treatment equipments, are exactly a kind of devices of Processing Ag ammonia waste water.
Background technique
During chemical silvering, silver-colored ammonia is gradually reduced and fails, and generates silver-colored ammonia waste liquid, silver is mainly with [Ag (NH3)2]+
[Ag (NH3)]+Form exists.Soluble silver salt and collargol are easily absorbed by blood of human body, generate serious prestige to human health
The side of body.Sulphide precipitation is common silver-containing waste water processing method, but sulfide may excessively generate colloid or more sulphur networks
Object is closed, is not suitable for selection critical point in engineer application and adds, cause the concentration of mercury out not up to standard.
Summary of the invention
The purpose of this utility model is, in order to improve the treatment effeciency of silver-colored ammonia waste water, proposes a kind of efficient silver-colored ammonia waste water
Processing unit, using contact break-precipitating-united method of absorption-UF membrane to realize the qualified discharge of silver-colored ammonia waste water and returning for silver
It receives.
To solve problems of the prior art, the purpose of this utility model can be accomplished by the following way: a kind of
Silver-colored ammonia waste water processing unit, including intake pump, waste pipe through intake pump connection settling vessel top water inlet, settling vessel it is upper
Clear liquid connects the water inlet on membrane separator top through intermediate lift pump, and the hollow-fibre membrane in membrane separator passes through outlet pipe and liquid
Flowmeter body, water outlet pump connection；Precipitating reagent adds the feeding opening that pump connects settling vessel top by chemical feed pipe, and it is logical that PAC adds pump
Cross the feeding opening on chemical feed pipe connection membrane separator top；Aeration tube of the air blower through gas flowmeter junctional membrane separator bottom.
The settling vessel top is installed by blender.
The utility model has the advantages that
The utility model has the following advantages compared with prior art: equipment operation is simple, and treatment effeciency is high.Vulcanized sodium and trip
From silver ion form silver sulfide precipitating, due to the adsorbable remaining Trace Silver of Powdered Activated Carbon, by Middle hollow fiber membrane,
Removal efficiency can be improved.The utility model wastewater treatment equipment comes using contact break-precipitating-united method of absorption-UF membrane
Remove the silver ion in desilver ammonia waste water.To make the processing up to standard of silver-colored ammonia waste water and discharge, while realizing the recycling of silver.

Specific embodiment
As follows referring to attached drawing 1: a kind of silver-colored ammonia waste water processing unit of continuous operation, it is heavy that waste pipe is connected through intake pump 1
The water inlet on 2 top of shallow lake device, the supernatant of settling vessel 2 connect the water inlet on 5 top of membrane separator, film point through intermediate lift pump 4
It is connect by outlet pipe with fluid flowmeter 7, water outlet pump 8 from the hollow-fibre membrane 6 in device 5；Precipitating reagent adds pump 13 by adding
Pencil connects the feeding opening on 2 top of settling vessel, and PAC adds the feeding opening that pump 15 connects 5 top of membrane separator by chemical feed pipe；Drum
Blower 11 connects the aeration tube 9 of 5 bottom of membrane separator through gas flowmeter 10；2 top of settling vessel is installed by blender 3.
Settling vessel is Organic glass column,Blender is stainless steel material, and stirring intensity is
182s-1；Membrane separator is Organic glass column,Inside is equipped with 1 hollow-fibre membrane, nominal pore size
It is 0.22 μm, effective area 0.5m2.Intake pump is pipeline pump, and vulcanized sodium adds pump, PAC adds pump and water outlet pump is compacted
Dynamic pump, fluid flowmeter and gas flowmeter are spinner flowmeter.Device using PLC (programmable controller control) control,
Fully automatic operation, PLC are programmed using general technology.Device be daily continuous operation 12h, wherein settling vessel be 7 intermittent water inflows and
Water outlet, by Liquid level；Membrane separator is that interval is discharged, and in every 10 minutes circulations, is discharged 8 minutes, sky aeration 2 minutes.
Test result shows: the dosage of vulcanized sodium is 6.5mg/L, and the dosage of active carbon is 0.2g/L, and settling vessel is anti-
20min between seasonable, when precipitating 5min, the silver concentration of UF membrane water outlet is being 0.3mg/L, removal rate 98%, and water outlet reaches " dirt
Water comprehensive discharge standard " (GB 8978-1996) requirement, provide the new and effective device of one kind for the processing of silver-colored ammonia waste water.
