Prospects of China's water treatment industry - 04

costs 2 2 Landscape Water Treatment Technology At present the physical landscape of water treatment technology is relatively simple consisting mainly of the processing technology point source processing in order to change the water based cutting pollution point source to handle air flotation filtration mainly endogenous to handle oxygen dredging for Lord For the landscape and environmental management of water bodies commonly used methods are 1 to filtering and oxygenation as the main characteristics of the physical methods 2 to put in drug control as the main characteristics of micro chemical methods 3 to increase the contact area with air the main features of the biological treatment method and 4 to on a regular basis the role of microorganisms inoculated with water as the main features of the ecological approach 2 3 Rainwater Treatment Technology Rainwater rainwater that belong to micro polluted water Collection of links dealing with relatively simple technology mainly to resolve the storage and water to maintain the problem the part of the governance landscape water treatment technology and

there is no essential difference 2 4 Technology Development Trend of Integrated Water Resources Management At present a single processing technology can not meet the requirements of the field of integrated water resources management in order to bioremediation purification compound represented by a variety of techniques is an inevitable trend of development Its core is the use of high performance composite microbial or hydroponic cultivation of plants the metabolic activity of aquatic animals and plants on the water environment in the ammonia nitrogen nitrite organic matter and other harmful substances transfer conversion and degradation reducing COD concentration of pollutants in water value the same time photosynthetic bacteria can use light and type a simple inorganic substances in water for photosynthesis fixed nitrogen and phosphorus in water and other elements at the same time producing oxygen increase the oxygen content of water so that aerobic micro organisms through its own role in the metabolism of organic pollutants in water and broken down into simple inorganic compounds to further absorb and use of the water ammonia nitrogen total phosphorus and other nutrients and other soluble pollutants reduce the degree of eutrophication allowing water to be purified

and restored to reach a new the ecological balance From a technical nature such purification technology of bioremediation is a natural resilience and self purification capacity of an enhanced Third China s rapidly growing water treatment industry market size 1 the industry development of the overall market size 2005 China circulating water system of governance and integrated water resources management industry the market scale of 31 52 billion yuan in 2008 to reach 53 04 billion yuan an increase of the speed continued to increase now nearly 20 The rapid growth of market size is a double pull the inevitable result of demand factors First under the control of a rigid national policy needs which is mainly manifested in the country promote the cause of water pollution control and promote the implementation of energy saving emission reduction emphasis on water recycling to solve water shortage regional water policy issues arising needs second is economic development and improved living standards resulting from internal demand mainly in urban upgrading and real estate development in the upscale community building people s demands for improvement in their living environment led to the park gr
