Abstract: The development of water treatment technology and equipment all undergo long-term development and play an important role in water resources. We also need to constantly improve the needs of the times. Through the application of advanced technology and equipment to overcome the shortcomings of the traditional methods, to protect the environment, energy saving effect, but also to ensure the orderly conduct of water treatment. In each link of the process also reached the appropriate standards, forming a virtuous circle, to curb misconduct in the operation, improve processing efficiency and efficiency. In view of this, this paper analyzes and discusses the application and development of environmental water treatment technology, for reference only. Key words: water treatment technology; water treatment plant; development; application First, the development of water treatment technology 1, the conventional water treatment Conventional treatment methods used more in sewage treatment, coagulation, sedimentation, filtration and disinfection as the main steps of treatment, is China's traditional treatment. Over time, the drawbacks of common approaches have become increasingly apparent and need to be optimized and new treatment technologies developed to reduce waste of resources and environmental pollution. To optimize the conventional treatment methods, different pretreatment and advanced treatment technologies need to be applied according to different water quality, and other treatment methods can be appropriately combined to improve the quality of treated water. 2, membrane processing technology Membrane processing or pharmaceutical treatment is the necessary treatment of water treatment in China, most of the water will be liquid chlorine disinfection. In developed countries will also use pharmaceutical water treatment, its research and development of pharmaceutical efficient and low toxicity, treatment costs are not high. In terms of industrial water treatment, China is close to pollution-free and non-toxic areas. Biodegradable pharmaceuticals are the main aspect of industrial water treatment in our country. Membrane processing technology requires the use of high-end equipment to overcome some of the shortcomings of traditional water treatment, through the specific membrane permeability, the filter membrane machinery as a basis, the water ions, impurities and molecules are screened out. 3, the depth of water treatment progress In the depth of water treatment, ozone - activated carbon adsorption technology is widely used, has a broad application prospects. In the high temperature and high algae period of raw water treatment, the application of ozone - biological activated carbon technology reflects its unique advantages, you can efficiently remove disinfection byproducts, precursors, algae, etc., to control bromate and effluent safety, to ensure that drinking water Safe depth processing technology. In the water pretreatment stage, the use of ozone pre-oxidation technology to reduce the burden of post-treatment. To ensure that the treated water reaches the effluent quality standard, the activated carbon needs to be added after the pre-oxidation of ozone or the biological filtration process is used. Which affect the technical treatment of many factors, ozone dosage, exposure to oxidation time, pH and the substrate and the properties of activated carbon. In the process of treatment, adjustments can be made in real time according to the corresponding standards of values ​​and specific biological communities in order to give full play to the role of ozone and activated carbon. 4, water quality engineering science The current water treatment technology is subject to various constraints, did not play a role in application, water treatment level also needs to be improved. The phenomenon of water pollution and shortage of water resources is becoming increasingly apparent and has a certain impact on the development of our country. The establishment of water quality engineering disciplines and other professionals, and constantly research and development of new water treatment technologies to meet water quality requirements and people's use requirements. All kinds of water treatment problems that emerge at this stage need to be solved through the development of this discipline and help to improve the technology and quality of water treatment. Second, the application of water treatment equipment 1, degassing and multi-functional device development Degassing device is to remove harmful odorous gases in water, its application effect far exceeds the conventional treatment equipment, a key part of the water treatment system, the more common is the CO2 appliance. In the current new degassing device, the new deaerator, CO2 removal device, such as the CO2 device has a better purification effect, according to the cyclone principle, the liquid gas separation. The application of multifunctional equipment in water treatment simplifies the structure of water treatment system. Its simple operation and high degree of automation can effectively reduce salt content and suit water quality with high alkalinity and hardness. If applied to boiler water treatment, can reduce the dirt displacement and improve boiler water quality. 2, reverse osmosis technology and electro-osmosis equipment Reverse osmosis membrane technology is the focus of water treatment, full application of pressure difference, with zero pollution, energy efficient advantages. Reverse osmosis technology can achieve intelligent and continuous operation, improve operator productivity. The technology can reduce the dosage of medicaments and reduce the environmental impact of water treatment. In China's water treatment research, reverse osmosis technology can be traced back to the last century 60's, the establishment of specialized agencies engaged in the technology and equipment research. Electro-osmosis technology is a desalination technology, different water contains different levels of salt, salt ions in the electric field to move in the opposite direction. Two ion exchange membranes are inserted into the electrodialyser. Anion exchange membranes allow the passage of anions freely, isolating the cations. The cation exchanger allows the passage of cations, isolates the anions, the directed migration of the ions reduces the salinity, and the compartment near the electrodes becomes the ion concentration pool, completely desalting the desalination chamber. In specific applications, the electrodialysis device is composed of hundreds of pairs of exchange membrane, to facilitate systematic treatment and improve work efficiency. 3, water filter structure Water treatment technology is constantly changing development, with its water treatment equipment updated. Different types of filters applied to the effect of water treatment will be great. Such as the new water filter, GR series filter high efficiency, the advantages of simple structure, the processing speed and carrying capacity than the traditional filter better.
