Since 2006, China PCB industry has maintained the world's first production scale.
Gradually expand from the continuous expansion, the impulse to bring energy and joy gradually dispersed, is in the fierce market competition, management strict restriction of various and environmental capacity.
Enterprises are the various does not adapt, psychological blank.
Even, some enterprises to invest in Vietnam, India and other countries.
But after the actual comparison, results show that China investment environment is first-rate, other countries can not match.
Then "a wind" like the China coastal "Pearl River Delta" "Yangtze River Delta" region into the mainland.
Now, to the mainland there exist many problems and difficulties, the outlook is not optimistic.
Where is the road of development and China PCB industry?
There are no measures to ensure the realization of sustainable and stable development of the PCB industry China?
Here, I want to environmental protection to ensure sustainable development view to talk about their own PCB industry.
To find out the balance point of economic development and environmental protection, science to develop environmental control standard.
In the aspect of sustainable development, we think that a positive attitude should be to achieve economic development, because the development is the hard truth, moreover PCB industry belongs to the state expressly to encourage the development of industry, on the other hand, attention should be paid to environmental cost, environmental cost, to realize the development with the minimum cost.
The "big eighteen" for our proposed building a modern beautiful China goal, is the scientific dialectical to bring the two together, the two are indispensable.
Our environmental protection departments must through a lot of investigation and research, find out the balance point of economic development and environmental protection, science to develop environmental control standard.
Scientific and forward-looking, overall, strategic and operational aspects in must.
In formulating or amending must study and Analysis on the standard of the above aspects of the control standard.
As the limit of copper ion in the wastewater discharge standard value, down to more stringent than developed countries, even more than the drinking water standard should be strictly, there is no need to?
Will not produce secondary pollution?
Enterprises paid a huge price to do standard worth?
Need serious consideration.
And as the standard limit of ammonia nitrogen from wastewater, repeatedly substantially reduced.
Ammoniacal cupric chloride etching PCB fabrication process with stable performance, convenient operation, control is simple, characteristics of etching effect is good, is widely used in PCB industry.
But this process has high content of liquid ammonia, which leads to ammonia nitrogen content also has high washing water.
At present industry of ammonia nitrogen treatment had no effective methods.
At the same time, the industry also no etching process mature alternative ammoniacal cupric chloride etching process.
Therefore, greatly reduce the ammonia nitrogen and total nitrogen emission limits, resulting in great pressure on enterprises, so before the formulation or revision of the standard should fully consider its operability.
We can learn from the EU in the launch of RoHS environmental protection standard, also not part of the material to substitute the immunity.
Associations are most concerned about environmental issues, hope by the National Central ASTRI led by China, Electronic Engineering Design Institute, and we do research, determine which criteria most favorable to the ecological balance, protecting the ecological environment.
The national finance, promote the progress and the promotion of environmental protection technology.
At present, PCB enterprise with intensified market competition, resource costs increase, enterprises operating difficulties, and many environmental protection technology is not mature enough.
If forced enterprises to meet the stringent requirements of environmental protection, not only for enterprises to increase the heavy economic burden, but also enable enterprises to increase of no small investment risk.
Science and technology is the first productivity!
Environmental protection index and strict must be based on environmental protection technology development.
On environmental governance issues we association also organized personnel to the Japanese study, the results found that the Japanese government is according to the environmental protection technology development gradually revision of environmental protection standards.
However, the development and promotion of environmental protection technology, and constantly improve the mature, require a longer process.
So, this process needs the strong support of the country, the country can even in this work to play a more important role.
Because once the advanced environmental technology widely used, of the largest gains among the government and the society, with the economic and social effect far-reaching.
Of course, our government is currently working on this, also has obtained the certain achievement!
We hope that the government departments to greater efforts in this regard, increase funding scale, reduce the "threshold", supported by the rapid development of progress and promotion of environmental protection technology, to meet the increasingly urgent environmental situation.
The development of circular economy, the waste feed waste, resource recovery of pollutants.
In the PCB production process, there are many process wastewater is generated due to the impurity content of water reaches a certain limit after the loss of the use of performance, must be discharged form wastewater.
If we can timely the impurities removed, so that the impurity content in the physic liquor in a certain standard, can make the potion repeatedly to obtain the full use, the amount of waste produced will also be greatly reduced, thereby reducing the difficulty of wastewater treatment.
In addition, the removal of the impurities, if can get efficient use, then achieve wastes the resources of the target, using waste environmental protection investment income balance, which is an effective way of sustainable development of PCB industry.
According to the author's experience, PCB technology, water reuse, recycling of copper or other metals can make the production of washing water, micro etching solution can be recycled, heavy metals extracted can realize resource.
However, there are many reuse technology is not mature, not long-term stable application, needs the enterprise and the technology company collaboration, risk sharing, make the new technology application and development in a timely manner.
A lot of precious metal used in our industry in the production process, we should increase the regeneration system in the production line equipment resource, which will not only can reduce the import of precious metals, and can greatly reduce the difficulty of sewage treatment and improve wastewater discharge standard.
Reasonable layout, look far ahead from a high plane, the PCB enterprise "live and work in peace".
Government departments should make full use of Scientific Outlook on Development, look far ahead from a high plane, reasonable layout, the correct guidance, scientific management, make PCB enterprise has stable operating areas and a good business environment.
If the enterprise improper location, causing many factory relocation movement, has great impact on the development of enterprises will be more talk, sustainable development.
For the PCB enterprises, we recommend choosing in coastal or estuarine location, abundant rainfall, away from the water source region.
We believe that with the right guidance and assistance to government departments, enterprises to actively explore innovation, technology service industry cooperation, we will be able to find the good response to the current difficulties, sustainable and stable development of the China PCB industry! |
