Origin of water pollutionCommunity sources.Sewage from a community source, causing water pollution is very bad water causing the problem. Waste water from a community water use in everyday life, including wastewater from bathroom wash washing water to cook the body excrete from all types of housing. Houses condominium market Shops, restaurants Restaurant halls The hospital. Hospital Hotel accommodation service car. Wastewater will be let go come from the strike, most of the water flowing into the river without treatment before. In addition to dry wastewater from sewer wastewater from flowing into the community plenty of water in such a way that there is no clear position, such as that caused by surface wash houses. Water runs off the surface of the road The wash water settling sand from areas where road construction and households monkan. Cord housing communities and households counted as waste water causing problems in current conditions. From the report of the Metropolitan Waterworks Authority has assessed the use of tap water each day, which makes it a condition of release, disposal and wastewater. Characterised by the devil has 85 Petit St further into the sewage water. These include sewage with little things drive that out of body waste. Other types of materials and dust combined with confused and cause spoilage. It is already visible inside the lower area of the River now, etc., however, the fee fiend wastewater that caused many areas of study, such as municipality, Samut sakhon. Approx. 5200 cubic meters per day. So what size of community. Thirdly, important factors such as in waste water discharge into water bodies and as inevitable in almost all countries, the communities are located along the water, it's a chance to make the waste water to spread into the body of water directly. The result followed in the long term, it is found that the soluble oxygen reduced lower back. By some of the remaining value is less than 1 mg/liter, etc.3. You will see that there are a lot of different pollutants in the sewage contamination in the community, such as organic sludge, dirt, sand, various germs. Their toxic insecticides. PB detergent oil from the vehicle. Toxins on the vehicles out of SOAP scraps disposable urine feces, as well as various waste materials and debris into the water directly. Most of the characteristics of the wastewater BOD values are approx. 150-250 mg/l. Acid-alkaline affinity, is approximately 6 to 8 is not too much acid or alkali. Substances in wastewater Ka Mara road, 20-100 mg/l. Although wastewater containing pollutants are not much, but since there is plenty and origin of many fragmented. Make rotten behavior of natural water resources from sewage from a community looks little little by little and are difficult to control, edit, 2. industrialPollutants, contaminants in the wastewater from industrial looks different according to the type of industry, such as Mills. Canned food factory jobs rose Brown Cassava starch production plant The beverage production plant wastewater containing organic matter a lot. Make up the wastewater BOD of this plant has a very high value is a value ranging from 700 up to 70000 mg BOD/l. Industrial chemical plant pesticides plant hole to squander a steel factory, living being. Textile factory Tanning factory to wastewater containing substances mix. A nuclear power plant to smelt the steel factory. The oil industry wastewater with high temperatures reaching 60 degrees may be kammantaphap oil contamination and radiation. The mining industry has been making water left with a lot of sand sediment. Wastewater from factories, mainly to release into water bodies through sewer it to control and treatment before release into water. Characteristics of wastewater from industry is very high BOD. With a high and low Contains a floating road, mamak Therefore, if the wastewater from industrial plants do not receive treatment before release into the water will affect the water quality in the water source, but if there are intense supervision and seriously, it is not difficult to prevent water pollution resulting from industrial plants. This time, factories often smuggle the wastewater from the sewage plant, one that has not yet been eliminating dirt, based on effluent standards. The industrial use of water in 81.1 States of water, wastewater from industrial waste, polluted water with up to 30 percent of all waste water from industrial wastewater with high concentration of toxins. If released to water immediately without wastewater before. The influence of water in the environment that has severe and quick: Brown beers, beverages plant, paper factory, producing ready-made foods. The discharged pollutants, etc., are a group of organic compounds that are able to degrade by microorganisms in the water, the gas ran out of oxygen in water decreases rapidly. There is a tanning factory, metal plating. Dyeing, etc to make wastewater with toxic substances and heavy metals contamination are very dangerous. Some types of aquatic organisms can also be accumulated and transferred through the food chain. 4. From the analysis report of the Institute of science and technology of Thailand.It was found that the various factory wastewater. Depending on the size and type of plant, such as. SR flour factory in Chonburi province water used in various organizations fall roughly 1, 785, 000 cubic meters per year. The oil mill nganklan, Chonburi, Thailand, all water must be left behind in the amount of 2,600,000. Cubic meter per year served, multiplied by 0.85, estimated to have an average effluent coming out. It is a very high quantity. These flow sewage spreads down to the Gulf of Thailand and dirty. Very seriously. In addition, there is a list of the quantity of wastewater from the Ministry of industry on almost all plain plant between 10000-40000 cubic meters per day, and in each category there will be waste listed in both heavy metals toxic radiation kammantaphap object. Of cardboard.
