Sources of water pollution

effluents from the community is the cause of water pollution. The area is causing the waste. Waste water from the community water use in everyday life, including effluent water from the toilet, washing laundry, cook food and purify the body. All types of housing Dwellings, condominiums, shops, markets, restaurants, dormitories, hospitals, nursing facilities, hotels and auto repair. Water is released from sewage pipes, most of which will flow into the river without prior treatment. The effluent from the drain drought Wastewater of large quantities flowing into the water in such a position is not as clear as water from the cleaning surface, the houses overflow road surface waters that wash sand from. Mr areas of road construction and homes
spilled community and residential homes. This is the area where most water is causing problems in the current conditions. The report of the MWA. Evaluation of water used each day at the left and turned into the devil effluent 85 cents operator has taken additional sewage entering the water, too. These effluents are made to express excretion from the body waste, dust and other debris mixed with campsites. And cause rotten. As already seen in the area of the lower Chao Phraya River, etc. However Volume sewage causes in many areas such as education, Muang District, about 5200 cubic meters per day. It can be said that the size of the community. It is a key factor in the release of sewage into the water. And as is inevitable in a country. Almost every community is located on the waterfront. I had a chance to spread sewage entering the water directly. The results come in the long run it is. Found that dissolved oxygen has to be reduced to very low. Some of the less than 1 mg / L. Etc.

will see that there are pollutants of many types of contaminants in wastewater, such as organics and bacteria, sediment, sand, pollution, pesticides, lead, detergents, oil from vehicles toxins out of the vehicle scrap. food, soap, feces, urine and waste disposal. And various waste directly into the water. Most of the community is the BOD effluent characteristics about 150-250 mg / liter. PH - about 6 to 8 is alkaline, not acidic or too alkaline. Substance floating in the water district, leaving the devil 20-100 mg / liter. Although water is a pollutant that is not much. But since there are plenty The origin of many fragmented. It looks rotten bodies of water caused by effluent from the community. A gradual manner And difficult to control, modify 2. Industrial pollutants. Contaminants in the wastewater industry is characterized by different types of industries such as food cans, paper factories, sugar mills and starch diets. Beverage production To discharge a large amount of organic material, the BOD of the wastewater, this is a very high BOD values ranging from 700 to 70,000 mg / liter industrial chemicals. Plant, animal disposal plant room. Steel mills Dyeing factory Leather Factory To discharge a contaminant is a nuclear power plant. Steel mills The oil industry will release water at temperatures up to 60 degrees may be radioactive. And oil contamination The mining industry has a lot of water with sand from most industrial effluents are discharged into the sewer water so convenient if you want to control and treated before being released into the water. The characteristics of the BOD effluents from industries are very valuable resources and is highly alkaline. Substance floating on a road So if the effluents from industry have not been treated before discharging into water bodies. Could affect water quality in the water violently. But if there is a supervisory And serious performance It's not difficult to prevent water pollution caused by factories. This time, the industry often illegally discharge waste water through the use of the plant, which is wastewater that has not been the elimination of dirty water standards, leaving total plant mass of water in the amount of 3 percent of the total water but. Wastewater from industrial wastewater contributed to 30 percent of all wastewater from industrial wastewater with high concentrations of toxic substances. If released into water immediately without sewage disposal before. To influence the water in the water is a perishable severe and include sugar, beer, liquor, beverage, paper and plant foods, and pollutant emissions are a group of organic compounds that can be digested. by microorganisms in water Hence, the oxygen in the water dropped quickly exhausted. A metal plating factory tanning, dyeing, etc., that are toxic effluent. And heavy metal contamination is extremely harmful. Life on the water Some species can also be accumulated and transferred through the food chain, with four of the analytical report of the Institute of Science and Technology found that plants release water as well. Depending on the size and type of plant. Such as flour mills, SR. Chonburi province Water used in various processes approximately 1,785,000 cubic meters per year. Refining plant in Chonburi want to leave all of the water. 2.6 million cubic meters per year, so if multiplied by 0.85, it will not drain out about average, which is a very high volume. Water will flow into the Gulf of Thailand spread. And a dirty very much. Also available from the Ministry of Industry. Almost all of the volume of sewage plants are ranged. 10000-40000 Cubic meters per day And in each category there will be Waste appear as microorganisms, heavy metals and toxic substances, radioactive solid dress.
