Abstract
The present invention relates to a kind of processing method of port cabin washing wastewater, mainly solve easily to pollute in the prior art, the problem of economy is bad.The present invention is by using a kind of processing method of port cabin washing wastewater, sequentially pass through regulating reservoir processing, the technical scheme that biological fluidized bed is handled, ozonation aerated biofilter integrated apparatus is handled and preferably solve above mentioned problem, available in the processing of port cabin washing wastewater.
Description
Technical field
The present invention relates to a kind of processing method of port cabin washing wastewater.
Background technology
Harbor chemical wastewater means that Liquid Chemicals in Bulk cargo ship needs cleaning or change the sewage produced during cargo type (such as to wash
Cabin, cleaning of evaporator etc.).Major pollutant in water is sweeping, the residual substance of cleaning of evaporator after unloading.The sewage is not only because it contains
There are the chemicals for being difficult to biological treatment, the cleaning agent as used in styrene, acrylonitrile, formaldehyde, cleaning cabin, and
Make wastewater flow rate and concentration that there is polytropy and randomness because dispersion single user wharf intermittent action, pollutant are various in style etc..One
As it is thought that the larger waste water of a class intractability.
Domestic liquid chemical freight volume is larger for Shanghai, Ningbo, Dalian, α Cygni Port, and chemical wastewater is by code
Head receive conveying tank field storage after enter wastewater treatment equipment, its wastewater treatment mainly using materialization-biochemistry combination process as
Main, most of materialization uses air supporting, biochemical then have the techniques such as biomembrane, oxidation ditch according to different water quality.China's harbour gives up
The processing of water has waste water processing station also in starting stage, only four Ports, according to the requirement of sustainable development, it is necessary to big
The process range into harbor chemical wastewater is pushed, makes shipping safer, ocean is more cleaned.
Chinese patent application CN104355383A discloses a kind of composite flocculation agent solution for being used to handle harbor oil-containing wastewater,
The formula of the flocculant solution is：Aluminum sulfate 4%-8%, ferric sulfate 4%-10% and chitosan 0.5%-2.5%.This hair
The bright preparation method for also disclosing above-mentioned composite flocculation agent solution.Effect using present invention processing waste water is significantly larger than single type
The treatment effect of flocculant, efficiency high, consumption is few, has the advantage of aluminum salt flocculant and Ferric Salt Flocculants concurrently, while having height
Molecular flocculant consumption is few, flco is formed soon, the advantage that settling property is waited well, and compensate for that each component is single to be used
It is not enough.It is particularly suitable for use in the coagulating treatment of harbor oil-containing wastewater, water ballast, tank washings.
It is more single for current handling process, it can only meet the processing requirement of specific water quality, Difficulty, and it is existing big
Most harbour sewage disposal systems are big due to that can not adapt to chemical cleaning of evaporator water change of water quality, the characteristics of strong toxicity, cause harbour dirty
Water treatment system, which can not be stablized, normally to be run.The characteristics of for current China's harbour chemicals cleaning of evaporator water, develop a kind of shock resistance
Ability is strong, is adapted to the group technology of different chemical product waste water, reaches economic, efficient processing, disposable waste water is entered
Row reuse, meets the trend of current construction conservation-minded society.
