At present, organic pollution and heavy metal pollution, replacing microbial pollution has become the biggest hazard. The census found that the waterworks with surface water as the water source failed, mainly because the total amount of organic compounds exceeded the standard. However, many water plants with groundwater as the water source have also exceeded the standards of fluorine, arsenic, iron and manganese. The total amount of organic compounds refers to the COD value in water measured by using potassium permanganate as an oxidizing agent. COD is commonly known as chemical oxygen demand, which indicates the amount of reducing substances (various organic compounds, nitrites, sulfides, etc.) in water.
Development status of water treatment technology:
According to the specific conditions of water quality, our water treatment technology is also constantly improving. The circulating water system treatment industry mainly includes equipment production and sales in several market segments of medium energy-saving central air-conditioning cooling circulating water treatment, refrigerating circulating water treatment, heating water treatment, centralized heating circulating water treatment, industrial cooling and refrigerating circulating water treatment. The comprehensive water resources management industry mainly includes several sub-markets of sewage treatment, landscape water reuse treatment, rainwater utilization, comprehensive utilization of urban sewage and wastewater, and comprehensive utilization of common sewage and wastewater. Tap water supply and others are mainly composed of tap water supply and other water treatment industries. At present, a single treatment technology has been unable to meet the requirements of the comprehensive water resources management field. Since there are many impurities in the water quality, different solutions are required for different requirements. Medically, it is necessary to prescribe the right medicine, and the same is true for the problem of water quality.
China''s water treatment industry prospects and influencing factors
the main factor of influence:
(1) The rigid demand under the control of national policies is mainly reflected in the demand triggered by the state''s policies to encourage water pollution control, promote energy conservation and emission reduction, pay attention to water resources recycling, and solve drinking water problems in water-scarce areas. These demand will mainly promote the rapid development of the circulating water market and the small and medium-sized industrial wastewater treatment market.
China is a water-deficient country with a per capita water resource share of only 2,300 cubic meters. The state attaches great importance to the protection and recycling of water resources, encourages the development of circular economy, supports sustainable development, vigorously promotes energy conservation and emission reduction, and attaches importance to the development of green environmental protection industries. These all involve the pursuit of water conservation and increased utilization.
(2) The intrinsic demand arising from economic development and improvement of people''s living standards is mainly reflected in the urban water reform and upgrading, the construction of medium and high-end communities, and the new water treatment needs of the park''s green space construction brought about by the people''s demand for living environment. This demand will mainly promote the development of rainwater, landscape water treatment and domestic sewage treatment markets.
Water treatment industry prospects:
Water is a precious resource for human survival and development. The seriousness and importance of the water problem have increasingly become the consensus of all walks of life. Water treatment is a global issue affecting everyone. Government departments at the central and local levels have put water issues at an important position, saving water and Accelerating the management of water pollution and promoting the recycling of water, water treatment will become one of the fastest growing industries in China.
