Abstract
The present invention relates to emergency field of waste water treatment, and disclose a kind of emergency wastewater treatment method.Present invention emergency waste water is delivered in raw water box, and the emergency waste water added in acid-base pair raw water box in raw water box carries out electrolyte, carrys out regulating water quality；The emergency waste water that water quality adjustment is completed, which enters, carries out electro-Fenton reaction in electrochemical reactor；Then the emergency waste water reacted enters tubular ultra-filtration membrane system and is separated；The waste water separated carries out the adjusting of pH value from flowing into PH conditioning tank；It adjusts the waste water finished to beat in into clear water reserviors, has reached the standard of discharge.The present invention can effectively remove the substances such as organic matter and ammonia nitrogen, reduce the injected volume of drug, so that the waste water of processing is not had the discharge of sludge, and occupied area is small, operates more convenient, conducive to promoting the use of in the market.
Description
Technical field
The present invention relates to emergency technical field of waste water processing, specially a kind of emergency wastewater treatment methods.
Background technique
As China's economic development and environmental pollution are increasingly serious, emergency water process demand is more and more, for example, transportization
Accident, the dam break of enterprise wastewater library, waste water station leakage, soil remediation place etc. occur for the vehicle or ship of product.Because large area is dirty
Surrounding body is contaminated, this usual emergency measure of event is exactly to shut off, collect.Several hundred tons for collecting in this way or even thousands of, up to ten thousand
Ton waste water, it is necessary to be handled using emergency processing facility to surface water quality standard, then qualified discharge.And this kind of water can only
Permission is disposed in 30~40 days, otherwise secondary pollution accident can occur because of Changes in weather.
The waste water quality at emergency event scene is complicated and changeable, and there are three types of specific classification: orgnic compound pollution, inorganization
Learn object pollution, heavy metal pollution etc., current most widely used equipment is that RO film etc. is implemented, still, RO film there are fouling membrane with
The insurmountable problem of concentrated water, and sludge can be generated.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, it the present invention provides a kind of emergency wastewater treatment method, solves in existing processing
The substances such as organic matter and ammonia nitrogen are not easy to remove, and sludge can be led to the problem of.
(2) technical solution
To achieve the above object, the invention provides the following technical scheme: a kind of emergency wastewater treatment method, including following step
It is rapid:
A. emergency waste water is delivered in raw water box, and the emergency waste water added in acid-base pair raw water box in raw water box carries out electricity
Xie Zhi carrys out regulating water quality；
B. the emergency waste water that water quality adjustment is completed, which enters, carries out electro-Fenton reaction in electrochemical reactor；
C. the emergency waste water then reacted enters tubular ultra-filtration membrane system and is separated；
D. the waste water separated carries out the adjusting of pH value from flowing into PH conditioning tank；
E. it adjusts the waste water finished to be drained into clear water reserviors, has reached the standard of discharge.
(3) beneficial effect
The present invention provides a kind of gel ink pens to sell box.Have it is following the utility model has the advantages that
The substances such as organic matter and ammonia nitrogen can be effectively removed, the injected volume of drug is reduced, do not have the waste water of processing
The discharge of sludge, and occupied area is small, operates more convenient, conducive to promoting the use of in the market.
Detailed description of the invention
Fig. 1 is present invention emergency wastewater treatment method figure.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1
As shown in Figure 1, a kind of emergency wastewater treatment method, comprising the following steps:
A. emergency waste water is delivered in raw water box, and the emergency waste water added in acid-base pair raw water box in raw water box carries out electricity
Xie Zhi carrys out regulating water quality；
B. the emergency waste water that water quality adjustment is completed enters in electrochemical reactor, and dioxygen is added in electrochemical reactor
Water carries out electro-Fenton reaction, and the principle of electro-Fenton reaction is similar with common Fenton, decomposes polluted source using hydroxyl radical free radical
In organic matter, reduce the COD of polluted source；
C. then the emergency waste water of reaction enters tubular ultra-filtration membrane system, puts into alkali in tubular ultra-filtration membrane system to adjust
The pH value of waste water is saved, molysite generation iron hydroxide can be passed through into tubular ultra-filtration membrane system under alkaline condition again and separated,
Below standard waste water is separated to be recycled by pumping to be re-fed into electrochemical reactor with this；
D. the waste water separated carries out the adjusting of pH value from flowing into PH conditioning tank；
E. it adjusts the waste water finished to beat in into clear water reserviors, has reached the standard of discharge.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
Claims (1)
1. a kind of emergency wastewater treatment method, which comprises the following steps:
A. emergency waste water is delivered in raw water box, and the emergency waste water added in acid-base pair raw water box in raw water box is electrolysed
Matter carrys out regulating water quality；
B. the emergency waste water that water quality adjustment is completed, which enters, carries out electro-Fenton reaction in electrochemical reactor；
C. the emergency waste water then reacted enters tubular ultra-filtration membrane system and is separated；
D. the waste water separated carries out the adjusting of pH value from flowing into PH conditioning tank；
E. it adjusts the waste water finished to beat in into clear water reserviors, has reached the standard of discharge.
