With the continuous development of economy in our country, the discharge of sewage and pollutants is increasing with each passing day, and the pressure on them to handle and release pollutants continues to increase. There is an urgent need to find new ways to dispose of waste. At this year's NPC and CPPCC National Committee members, Li Ziying, member of the CPPCC National Committee and dean of the Beijing Institute of Geosciences, submitted a proposal on "strengthening the research on technology of deep well disposal of wastewater and opening up new avenues for handling pollutants".
Li Ziying introduction, wastewater deep well disposal technology is a new sewage treatment technology, is the case of suitable geological conditions, the use of multiple sealed materials to build a deep well, the high pressure pump will be injected into the closed wastewater, there is still a great use of space Of the geological storage space, underground drinking water resources to maintain a sufficient safe distance, so that polluted water or pollutants and the biosphere isolated, so as to achieve the purpose of disposal of safe waste water.
Li believes that no matter from the geological conditions or from the experience of deep well construction, our country has the foundation for deep well disposal of wastewater. Sedimentary rocks in China are widely distributed. Cenozoic and Mesozoic basins are mostly continental sediments. Most of the Paleozoic basins are marine sediments, with good permeability of sand and conglomerate, and have a thick and stable aquifuge with upper drinking aquifers, large Geological conditions are stable in most areas and are the ideal pollutant disposal layer. A great deal of engineering activities such as geological prospecting and mineral resources exploitation are carried out, and a large contingent of professionals with rich deep well drilling technology and experience can provide for the construction and operation of deep wells. Engineering and manpower support; a set of regulations, management methods and procedures for the management of geo-environment and geological disasters have been established, which can also provide security for carrying out deep-well disposal activities.
Li Ziyin suggested that the research work on wastewater deep well disposal should be carried out in time. The pilot study on geo-site selection, geological characteristics and engineering technology, environmental impact monitoring technology, laws and regulations and standards Research and formulation or revision of other research work, the establishment of deep well disposal demonstration sites. On this basis, to carry out research and promotion of other deep-water waste disposal technology.
