Description
Technical field
The utility model belongs to industrial waste water treatment, is related to a kind of removing setting for spent acid and heavy metal in waste water
It is standby.
Background technology
Graphite is a kind of important resource nonmetallic mineral, have good anticorrosive, radioresistance, conduction, heat conduction, from
The performances such as lubrication, high-low temperature resistant, tool has been widely used and important role in China's economic development and science and technology modernization.Stone
Frequently with mixed acid process, acid-base method and high temperature method, these methods can generate largely the preparation method of ink during preparing graphite
Waste liquid containing spent acid and heavy metal, wherein spent acid mainly include hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, and heavy metal mainly includes
Cadmium, mercury, nickel, zinc, chromium.The direct emission of these waste liquids not only results in serious environmental pollution, and is also the waste of resource.
At present, the method for mainly taking spent acid method of disposal acid-base neutralization；Agglutinant pair is mainly commonly used to the method for disposal of heavy metal
Heavy metal is aggregated, and then removes heavy metal with filter membrane.These need to consume big to the minimizing technology of spent acid and heavy metal
The alkali and agglutinant of amount, cost is higher, and when particularly handling a large amount of industrial wastewater, costly, manufacturing enterprise bears expense
It is heavier；Agglutinant is ineffective to the heavy metal adsorption of low concentration, and heavy metal removing is not thorough.
Invention content
For the utility model in the prior art, graphite produces the processing of spent acid and heavy metal contained in the waste water generated
There are of high cost, halfway problem is removed, the equipment of spent acid and heavy metal in a kind of removal waste water is provided, concrete scheme is：
The equipment of spent acid and heavy metal in a kind of removal waste water, the interior top of filtering ponds of the equipment are equipped with filtering fence,
Filtering fence one end is designed with waterwater entrance, and waste water inlet pipe is equipped with above waterwater entrance, and the other end is designed with filtering water outlet,
Filtering ponds side below filtering water outlet was equipped with drainage outlet pipe, crossed drainage outlet pipe other end connection evaporator, evaporator
Bottom is equipped with waste water comb, waste water comb other end coupled reaction pond, and reaction tank bottom is equipped with reaction tank drainpipe, reaction
The pond drainpipe other end is connect with acid-base neutralization pond, is designed with filter screen in the middle part of acid-base neutralization pond, is designed on filter screen multiple
Filter hole, acid-base neutralization pond lower section side are equipped with drainpipe, are equipped with spent acid gas outlet pipe at the top of evaporator, spent acid gas goes out
The pipe other end is connect with absorption tower, and top is equipped with nozzle in absorption tower, and nozzle connects water inlet pipe, is equipped with and draws water on water inlet pipe
Pump, absorb the bottom of the tower are equipped with acid solution outlet pipe, and the acid solution outlet pipe other end is connect with acid solution collecting pit, the installation of acid solution collecting pit bottom
Have collecting pit acid solution outlet pipe, collecting pit acid solution outlet pipe is connect with acid-base neutralization pond, acid-base neutralization pond and reaction tank respectively with pH tune
Regulating device connects.
The filtering fence and filter screen can be unpicked and washed and be reused.
The beneficial effects of the utility model are：Filtering fence in filtering ponds carries out prefiltration to waste water, removes in waste water
Larger solid particulate matter；The waste water for removing solid particulate matter enters evaporator, and thermophilic digestion, acid solution are carried out in evaporator
Low boiling point quickly evaporate into absorption tower, in absorption tower under the spray effect of nozzle, forms mix acid liquor free from foreign meter, flows
Enter to acid solution collecting pit and preserved；It removes waste water comb of the waste water of acid solution through evaporator bottom end and flows into reaction tank, pass through pH
The pH in reaction tank is turned up in regulating device, and the heavy metal in reaction tank is made to generate heavy metal hydroxide；Contain heavy metal hydrogen-oxygen
The reacted pond drainpipe of waste water of compound enters acid-base neutralization pond, under the action of the filter screen of acid-base neutralization pond, heavy metal hydrogen
Oxide is located on filter screen, and the higher aqueous of aggregation pH value below filter screen regulates and controls acid solution collecting pit by pH regulating devices
Interior mixed acid is entered in the aqueous below filter screen, is in neutrality aqueous, can reach the discharge standard of industrial wastewater.
Filter screen can be taken off, and facilitates the heavy metal hydroxide of heavy collection on removal filter screen, can inhibit a generated huge sum of money
Belong to hydroxide to anchor in acid-base neutralization pond, realize the thorough removal of heavy metal.
The equipment can handle the largely industrial wastewater containing spent acid and heavy metal, and practical value is high, sewage disposal into
This is low, removes thorough, and the mix acid liquor of preparation can neutralize the aqueous in acid-base neutralization pond with recycling, improve mixing
The use value of acid solution avoids waste.
