Abstract
The present invention is a kind of photovoltaic industry sewage classification processing method, is concretely comprised the following steps：Categorised collection is carried out to sewage using different pipelines in the sewage collecting stage, sewage is divided into organic wastewater, particle waste water, conductance waste water high and acid-bearing wastewater；Organic wastewater is processed using MBR techniques, its water outlet is reached reuse standard；The method being combined using press filtration and sand filtration is processed particle waste water, its water outlet is reached reuse standard；Conductance waste water high is processed using double film extracting and concentrating technologies, its water outlet is reached reuse standard；Acid-bearing wastewater is processed using white lime combination depositing technology, its water outlet is reached discharge standard；The water for being up to reuse standard imports reuse pool, the water source as industrial water, cooling tower moisturizing water；The water for being up to discharge standard is directly discharged.Traditional dilution discharge thinking is adjusted to treatment for reuse thinking by the present invention, reduces sewage discharge, realizes the recycling of water resource, reduces production cost.
Description
Technical field
The present invention relates to the technical field of photovoltaic industry sewage disposal, more particularly to a kind of photovoltaic industry sewage classification treatment
Method.
Background technology
The silicon chip working process of photovoltaic industry can produce organic wastewater, particle waste water, acid-bearing wastewater, conductance high to give up
Water etc..The common processing method of these waste water is first to mix water, if mixing water can reach discharge standard, mixes heel row
Put；If certain index is unsatisfactory for discharge standard, the index for the standard that is unsatisfactory for is processed, rear discharge up to standard.This treatment side
Although method realizes sewage qualified discharge, but the demand for development of green circulation economy is simultaneously not implemented, and causes the waste of water resource.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of photovoltaic industry sewage classification processing method is provided.
The present invention to achieve the above object, using following technical scheme：
A kind of photovoltaic industry sewage classification processing method, concretely comprises the following steps：
(1) by the analysis to silicon chip working process and sewage quality, different pipelines pair is used in the sewage collecting stage
Sewage carries out categorised collection, and sewage is divided into organic wastewater, particle waste water, conductance waste water high and acid-bearing wastewater；
(2) processed using different processing methods for different types of waste water：
Organic wastewater is processed using MBR techniques, its water outlet is reached reuse standard；
The method being combined using press filtration and sand filtration is processed particle waste water, its water outlet is reached reuse standard；
Conductance waste water high is processed using double film extracting and concentrating technologies, its water outlet is reached reuse standard；
Acid-bearing wastewater is processed using white lime combination depositing technology, its water outlet is reached discharge standard；
(3) will adopt and organic wastewater, particle waste water and the conductance waste water high of reuse standard are reached after being treated variously for lead
Enter reuse pool, the water source as industrial water, cooling tower moisturizing water；The acid-bearing wastewater that discharge standard is reached after treatment is straight
Run in and put.
Described pair of film extracting and concentrating technology includes ultrafiltration membrane treatment technique and reverse osmosis membrane processing technique.
The beneficial effects of the invention are as follows：Traditional dilution discharge thinking is adjusted to treatment for reuse thinking by the present invention, is reduced
Sewage discharge, realizes the recycling of water resource, reduces production cost.
Brief description of the drawings
Fig. 1 is schematic flow sheet of the invention；
It is described in detail referring to the drawings below with reference to embodiments of the invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of photovoltaic industry sewage classification processing method, concretely comprises the following steps：
(1) by the analysis to silicon chip working process and sewage quality, different pipelines pair is used in the sewage collecting stage
Sewage carries out categorised collection, and sewage is divided into organic wastewater, particle waste water, conductance waste water high and acid-bearing wastewater；
(2) processed using different processing methods for different types of waste water：
Organic wastewater is processed using MBR techniques, its water outlet is reached reuse standard；
The method being combined using press filtration and sand filtration is processed particle waste water, its water outlet is reached reuse standard；
Conductance waste water high is processed using double film extracting and concentrating technologies, its water outlet is reached reuse standard；
Acid-bearing wastewater is processed using white lime combination depositing technology, its water outlet is reached discharge standard；
(3) will adopt and organic wastewater, particle waste water and the conductance waste water high of reuse standard are reached after being treated variously for lead
Enter reuse pool, the water source as industrial water, cooling tower moisturizing water；The acid-bearing wastewater that discharge standard is reached after treatment is straight
Run in and put.
Described pair of film extracting and concentrating technology includes ultrafiltration membrane treatment technique and reverse osmosis membrane processing technique.
Traditional dilution discharge thinking is adjusted to treatment for reuse thinking by the present invention, reduces sewage discharge, realizes that water is provided
The recycling in source, reduces production cost.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented and do not receive aforesaid way
Limitation, as long as employing method of the present invention design and the various improvement that carry out of technical scheme, or not improved direct application
In other occasions, within protection scope of the present invention.
