Innovation and production
The result is not obvious if it takes a long time. But those who can deal with initial turbidity of water in particular can also be used in combination and coagulation.
The effects of this method are faster, better
Put water in the barrels, tanks and basin. Crushed alum and then added it into the alumina tube which is a bamboo tube that at the end of the tube drilled holes 20-30, to break down the middle of bamboo. Or wrap with gauze, tied to wooden poles, then add water, stir it towards a certain direction, quickly at first, then slowly in 3-5 minutes, when the flocculent appeared after standing for half an hour. After the flocculent precipitate on the bottom of the tube, water is clarified. Alum powder can be put directly into the water, how many doses of the muddy water depend on the case may be. Stir it towards a certain direction in a few minutes, and after standing there After the flocculent precipitate on the bottom of the tube.
If Bicarbonate content in the water is too low, it is not easy to agglutinate. Tam can be added 2-3 grams stone into the water in order to promote agglutination
Make water through the filter material to remove seston in the water and micro-organisms, thereby improving the quality of water. Compared to Alum precipitation, it needs more time and can meet the needs of a large quantity of water, and can get more thorough effect of water purification.
Simple water purifier
The water from rain is dirty; the source of water pollution is more serious, especially in the high turbidity of water Formation, which is in the need for purification before use.
The water of bathing under gravity falls on the bathroom floor, and then flows into the water tanks through the introduction of the water hole under the shower room. In this way, put up the used water storage. The water used in washing machines could be saved through the washing machine water pipes into the storage tank. the water tanks as a result of river water level is lower than the old toilet water taps, in accordance with the principle of atmospheric pressure and the pressure principle must be an adjacent water tank holding a small pumps, small pumps can be able to get the used water into the water tank in the toilet. You can also receive a small water pump next to a faucet, such as for wiping the floor. (The design process is from junior high school physical principles of atmospheric pressure Principle River to low water levels in water tanks of water, drawn through a small pump above the toilet, the use of junior high school physics clicks knowledge).
Biochemical method of treating sewage
Untreated waste water was flowing through a long way to go will gradually clean, odor disappeared, this phenomenon is a natural body of water purification. Micro-organisms in the water plays the role of clean water, they use organic pollutants in water as its nutritional food, through adsorption, absorption, oxidation, decomposition and other processes, put the organic compounds into simple inorganic substances. This process not only satisfies the reproductive and life activities of the microorganisms themselves, but also purifies the sewage. Fungi, algae and protozoa and other micro-organisms, has a strong absorption, oxidation, the ability to break down organic pollutants. In their waste disposal process, they have different requirements of oxygen, which can be divided aerobic biological treatment to into two types: aerobic and anaerobic processing. Aerobic treatment needs oxygen, and anaerobic processing doesn’t need oxygen. Wastewater biological treatment is the oldest, most widely-used and effective method, especially suitable for the treatment of organic wastewater.
