Polycrystalline silicon photovoltaic subsidies serious pollution solar panels?

Now everybody's environmental protection consciousness is more and more strong, the points of attention more and more, in the field of new energy, the solar panels, the problem of pollution, everyone have different opinions, points are summarized below small make up an objective for everybody, for your reference. 1, after

now everyone's environmental protection consciousness is more and more strong, people more and more attention. In the field of new energy, solar panels from everyone pollution problems have different views. Here are some key points are briefly summarized, for your reference. 1. Through calculation, the whole process can consume energy in a few months by solar energy equivalent recovery. 2. The pickling waste acid in the process of production by other companies as a hazardous waste recycling, Companies in strict accordance with the environmental protection standard operation, it is not a problem) 3. Production process of nitrogen, fluoride, dust and hydrogen chloride by spray tower and dust collector for reduction. Wastewater by flocculation and precipitation usually handle, reach gb8978 standards. Most of slag is a silicate slag, belong to solid waste. 4. There is no enterprise buried silicon tetrachloride. 1. Landfill silicon tetrachloride show that the factory do not have chlorine hydride ( Silicon tetrachloride is converted to chemical) , the cost will be far more than its peers. It will shut down. 2, silicon tetrachloride can be sold. On silicon materials: 1. It is a manufacturing and processing industry. Polycrystalline silicon melt in the crucible, ingot casting is cut into pieces, film formation. Is basically acid and dust. They are to deal with it very well. 5. In addition, there is no direct emissions cross-linked with the possibility of hydrogen silicone, because the water in the empty gas will be broken down into hydrogen chloride smoke and silica powder. To sum up, the old polysilicon production process the pollution caused by a relatively large. In order to control cost, domestic small factory also save a lot of post-processing links and labor protection measures, thus caused a lot of pollution and harm. However, the true standardized big factory production of polysilicon can achieve environmental protection, low emissions and low cost. Hetian new energy co. , LTD adhere to this principle. To the quality strives for the survival, to the quality strives for the development; Idea, we in the production of 100% comply with ISO9001 quality standards, each process has a strict quality control.
