Abstract
The present invention relates to technical field of sewage, particularly relate to a kind of method processing heavy metal wastewater thereby.The present invention provides a kind of method processing heavy metal wastewater thereby, comprises the following steps: step A: removes major part oils and fats through oil interceptor, by sodium hydroxide, acid waste water is adjusted to neutrality in homogenizing pond；Step B: promoted such as air-float integral equipment by pump, add PAC, PAM and carry out coagulation-flocculation precipitation；Step C: sedimentation tank water outlet mixes heel row at mixing point with mold clean waste water and enters municipal pipeline.Present invention process is simple, removal efficiency of heavy metals is high and environmental friendliness, it is easy to popularization and application.
Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of method processing heavy metal wastewater thereby.
Background technology
Along with developing rapidly of China's industry, thing followed problem of environmental pollution highlights day by day.Owing to heavy metal can only
Converting and migrate and can not degrade, therefore its problem of environmental pollution is especially prominent.
The minimizing technology of heavy metal ion mainly has at present: Physical, chemical method and bioanalysis, and these methods are respectively arranged with excellent lacking
Point.Chemical method is traditional and the heavy metal pollution treatment technology of practicality, by adding precipitant in water body, makes heavy metal be sunk
Form sediment and remove.This method processing cost is low, convenient management, but owing to needs add chemical agent, therefore easily causes secondary pollution.Raw
Thing method strong adaptability, equipment is simple, selectivity good, but owing to biology needs domestication, and general to process the cycle relatively long.Physical
In absorption method owing to environmental pollution is little, be easily achieved a large amount of process, therefore promise well in the process of heavy metal wastewater thereby etc..
At present, more adsorbent is applied to be mainly various Carbon Materials, such as activated carbon, Carbon fibe, CNT, Graphene etc., these
The preparation cost of material is higher, limits its application in terms of waste water process to a certain extent.Nanometer Mn2O3 is due to tool
Have the electricity of excellence, magnetics, adsorb, the characteristic of the aspect such as catalysis causes the extensive concern of people.The nanometer material of loose structure
Expect, due to features, relatively solid material such as density are little, specific surface area is big, there is more preferably performance, therefore as sides such as adsorbing materials
Face shows huge application potential.
Summary of the invention
For defect or deficiency present in prior art, the technical problem to be solved is: provide at a kind of
The method of reason heavy metal wastewater thereby, the method is the most effective, cheap, environmental friendliness.
To achieve these goals, the technical scheme that the present invention takes is a kind of method processing heavy metal wastewater thereby of offer,
Comprise the following steps:
Step A: remove major part oils and fats through oil interceptor, by sodium hydroxide, acid waste water is adjusted to neutrality in homogenizing pond；
Step B: promoted such as air-float integral equipment by pump, add PAC, PAM and carry out coagulation-flocculation precipitation；
Step C: sedimentation tank water outlet mixes heel row at mixing point with mold clean waste water and enters municipal pipeline.
As a further improvement on the present invention, described step A increases winding shaft, pump be promoted to homogenizing pond and mold clean
Waste water mixes,
As a further improvement on the present invention, the inflow of the air supporting water outlet in described step B MBBR pond carries out aeration.
As a further improvement on the present invention, being additionally provided with second pond after described step sedimentation tank, MBBR water outlet flows into two and sinks
Pond carries out solid-liquid separation, and base sludge is back to MBBR unit to maintain system sludge concentration, excess sludge to sludge concentration tank,
After carry out processed.
The invention has the beneficial effects as follows: present invention process is simple, removal efficiency of heavy metals is high and environmental friendliness, it is easy to promote
Application.
Detailed description of the invention
The present invention provides a kind of method processing heavy metal wastewater thereby, comprises the following steps:
Step A: remove major part oils and fats through oil interceptor, by sodium hydroxide, acid waste water is adjusted to neutrality in homogenizing pond；
Step B: promoted such as air-float integral equipment by pump, add PAC, PAM and carry out coagulation-flocculation precipitation；
Step C: sedimentation tank water outlet mixes heel row at mixing point with mold clean waste water and enters municipal pipeline.
Described step A increases winding shaft, pump be promoted to homogenizing pond and mix with mold clean waste water,
Air supporting water outlet in described step B flows into MBBR pond and carries out aeration.
Being additionally provided with second pond after described step sedimentation tank, MBBR water outlet flows into second pond and carries out solid-liquid separation, base sludge
Be back to MBBR unit to maintain system sludge concentration, excess sludge to sludge concentration tank, after carry out processed.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
