Environmental Protection Measures With Regard To Implementation Of Wastewater Underground Injection Technology

At present, the main way of treating sewage is to reduce the harmful waste discharged, decrease the pollution to the water environment, and make the industrial waste suit to the discharged standard. But the projection of underground injection designed by Dupont has broken the tradition way of treating sewage, and the technology which injected sewage into the deep underground caused the amount of waste water discharged to zero discharge, and conformed to the waste water processing standard in our country.The present paper the underground injection project take the Dupont titanium oxide powder project in the domestic implementation as an example, the detailed introduction of the project underground injection in the domestic and foreign research progress, mainly take overseas to the application and the promotion which underground injection as the example. In view of underground injection project has related legal laws and regulations content which the project the technical level and underground injection, the present paper mainly selects material from US'S research progress and the development history.In the paper, the technology of underground injection has covered many various contents, just like the selected location, the injection well , inject the fluid into the level wall of a well the compatibility , the operation and the monitoring, the closure inject into specification and so on the well, these all injected problem which in the technology could not omit, especially take the selected location as the important content, once chose in the earthquake belt perhaps the geothermic not steady area, underground injection the technology could not be able to play the protection environment role. The present paper mainly is take the US technology of underground injection as the foundation. By studying the Dupont injection the project, cause lots of domestic issue that should be solved now. And then, advising a comfortable underground injection project for our country.This involves to our country sewage treatment policy, the solid fills in buries the policy, the technical feasibility issue, as well as the management and the risk guard question, is needs the content which at present the condition produces according to our country cannot be neglected, is technical question which the implementation underground injection needs to solve. The same question is the application of underground injection has also touched our country legal laws and regulations and inspector general management mechanism contents. For example, process of underground injection caused an accident which will concern the legal liability, and than, after the accident in which way should be toke to make down the influence and so on. These contents all are in our country law laws and regulations stratification plane blanks. Therefore the basis the present situation, proposed the suitable policy and the environmental protection measure to our country as well as surveillance management mechanism.The application of underground injection also has mentioned the law of trade, the department of management, such as the system of charging pollution and so on. Underground injection is not only the technology of treating sewage, but also the method of pollution, so there will be reset the principle of charging pollution. Who should take the duty if there was an accident during the operation. These contents have not appeared on the law, so we should according to the situation to making a suitable policy and environment protection measurement, which advanced the application and the promotion of underground injection in our country.Finally, as far as the underground injection project concerned, the paper makes a decision of the project should be suit to our country really situation, achieves humanist, realizes the economical, social and the environment coordinated development.
