Excessive nitrate water treatment plant
Miao Jie Feng in Beijing excessive nitrate in water science and technology limited development of a special water treatment systems, verified by users after using for a long time, our water for nitrates exceeded the design of this processor has a special water appearance, covers an area of small, simple operation, high degree of reliability. Completely solve the excessive nitrates.
Nitrate is introduced:
Nitrate (NO3-) and nitrite (NO2-) respectively, nitric acid (HNO3) and nitrous acid (HNO2) acid, which occurs widely in nature as environmental pollutants, especially in water vapor, surface water and groundwater, as well as animals and plants and food. Sources of nitrate and nitrite pollution in the environment, such as: 1. artificial fertilizers: ammonium nitrate, calcium nitrate, potassium nitrate, sodium nitrite and urea; 2. domestic sewage, solid waste and human and animal waste, according to test 1-litre sewage in natural degradation process, can produce 110 mg of nitrate; 1 kg of garbage waste compost after leaching decomposition under natural conditions, can produce 492 mg nitrate; 3. food, fuel, oil refineries and other plants emit a lot of ammonia-containing waste, bio-and chemical conversion after formation of nitrates into the environment; 4. automobiles, trains, ships, aircraft, boiler, heating furnace burning fossil fuels such as coal, natural gas, produces large amounts of nitrogen oxides, an average of 1 ton of coal combustion, 1000 litres of oil and 10,000 cubic metres of natural gas produces carbon dioxide gas 913 63 kg, which after precipitation leaching, nitrogen dioxide gas can form nitrate to descend to the ground and in the water; 5. food preservation and storage: nitrates and nitrites are widely used in meat and fish preservation and preservation to make meat appear red and smell, in every kilogram of added nitrite to meats (usually sodium nitrite) 5 mg, color look good over time; Join at least 20 mg, stable colors that can be rendered to commercial needs; Add 50 mg of a special smell.
Chemical fertilizer application in your environment, effluent irrigation, refuse, industrial nitrogen-containing wastes, nitrogen-containing waste gas from fuel combustion emissions, under natural conditions, nitrate leaching from decomposed form by precipitation, flows into rivers, lakes and into the ground, causing the nitrate pollution of surface water and groundwater. As sewage Xia infiltration, dirt irrigation and which Shi fertilizer can makes groundwater nitrate content by number mg/rose surge to 400 mg/rose above (national life drinking water nitrate content health standard is less than 88.6 mg/rose, to nitrogen meter is less than 20 mg/rose); which Shi fertilizer, dirt irrigation, with nitrate pollution of water irrigation also makes crop absorption has large of nitrate class, as too fertilization by produced of spinach in the each kg dry heavy can containing Asia nitrate up 3600 mg. With a pickling stain of sauerkraut, a long-distance transport and long-term storage of vegetables and cooked vegetable overnight not only a substantial increase in nitrate content, and in the presence of nitrate-reducing bacteria, nitrate is reduced to nitrite.
Above contains a lot of nitrite and nitrate in drinking water, vegetables, grains, fish, meats, marinated sauerkraut, overnight after food, the cooking and a lot of nitrite can make direct poisoning, nitrate is reduced to nitrite in the human body. Interaction between nitrite and blood to form methemoglobin, which makes the blood loses oxygen-carrying capabilities, making oxygen toxic, light dizziness, palpitations, vomiting, mouth and lip cyanosis, confusion, convulsions, Hu quickly, rescue time can be life-threatening. Not only that, the nitrite in the body category with secondary amines to form nitrosamines, which reaches a certain dose is carcinogenic in human body, teratogenic, mutagenic substances, can seriously harm human health. To prevent nitrate and Asia nitrate of against, except to science reasonable to application fertilizer, ban using sewage irrigation, implemented sewage, garbage and stool harmless of processing, environmental measures to protection surface water and underground water not suffered nitrate and Asia nitrate pollution outside, also should as less eat pickled, smoked, La business of fish, meat, sausage, bacon, ham, canned food, stains sauerkraut, salt pickled soon of dish; Don't buy store longer or wilting vegetables on alternate days; Buy of the day dish eaten on the day; Do not eat overnight and cooked vegetables; Leftovers may not be stored for a long time; Not nitrite for industrial use (such as sodium nitrite) as salt ingestion.
