   todays water situation

   people are drinking every day, but because of their common and neglected. In recent years, with the rapid development of urban, industrial pollution, agricultural pollution, domestic pollution and other water brought to life a great threat. Chinese Academy of Sciences released national conditions research report: China 532 investigation pollution of rivers carried out show that 436 rivers have been polluted to varying degrees. China eutrophic lakes to reach the level of more than 63.6%. In densely populated areas of China, lakes and reservoirs have all been contaminated. At present my countrys rural areas are about 190 million people substances in drinking water harmful exceeded, concentrated in urban sewage discharge, water purification capacity beyond the grave. Water pollution has become a human health invisible killer! Now water pollution has come to help but we do not pay attention to the point where!

   water pollution and disease

   Medical experts recommend to protect the health concerns should daily glasses of water every life begins. 2/3 human tissue composed of water. Water is an important material to maintain the bodys physiological and metabolic activities. You must ingest 2-3 liters of water a day to maintain basic life activities. If sufficient water, blood, lymph circulation, the body can effectively absorb food nutrients, and excess substances such as toxins excreted.

   long-term safe and clean drinking water can bring health and longevity, while drinking unclean water, especially water polluted by heavy metals, it will cause a lot of terrible disease. According to the World Health Organization survey, 80% of human diseases related to water, poor water quality can cause a variety of diseases. World Health Organization survey showed that: 50% of child deaths worldwide is due to drinking contaminated water caused 25 million children a year die from drinking contaminated water caused by the disease, there are 1.2 billion people around the world and from drinking contaminated water suffering from various diseases, people died every day due to water, there are five million and more. In developing countries, 80% of cases and a third of the deaths are due to unclean drinking water caused. my country also has 500 million people from drinking unhealthy water led to illness and death each year.

   The main pollutants in tap water into the following categories:

   1, suspended solids: sand, rust, visible objects

   2 microorganism: bacteria, toxic cases, algae, etc.

   3, was dissolved inorganic: carbonate calcium, magnesium, sulfate, chloride, nitrate

   4, heavy metals: mercury, arsenic, lead, cadmium, chromium, etc.

   5, organics: pesticides, fertilizers, various industrial by dissolving, dyes, detergents, disinfectants

   6, particle radiation: radiation particle nuclear industry and nuclear medicine generated

   in addition to current water plant industrial water, tap water to the remaining civilian three strictly monitored and sprayed disinfectant in front of the tube, so as to achieve health indicators issued by the State in terms of color, turbidity, smell and taste and so on. This point of view, water is the health and safety of drinking water. In real life, however, we still often see the muddy, smelly water. Perhaps we invisible impurities in it. Water purification is easily disturbed by various factors, such as weather, human reasons and the like; secondary pollution of water is another main reason. Dilapidated water distribution network, high-rise buildings of no long-term storage and other clean-up of secondary pollution of water and have become important problems.

   At present, my country uses the traditional water treatment technology has been used for nearly 200 years, including coagulation, sedimentation, filtration, chlorination and other processes. It can remove some of the suspended solids, colloids and some bacteria. And tens of thousands of chemical pollution and other pollutants produced by modern industrial water quality impact, but it seems powerless. The impact of this pollution on the human body is a potential, long-term, tremendous. Especially the currently used "chlorination process," the residual chlorine and organic matter in water of the water reaction of chloroform, the World Health Organization has been identified as a carcinogen severe.
