摘要:
Drainage water containing organofluorine compounds is introduced into a micro-nano-babble generation tank (1) wherein microorganisms from a microorganism tank (61), a micro-nano bubble auxiliary agent from an auxiliary agent tank (50), a nutrient from a nutrient tank (52) and micro-nano-babbles generated by a micro-nano babble generator (23) are added to the drainage water so as to produce treatment water. The treatment water is fed from the micro-nano babble generation tank (1) to an active carbon tower (4) wherein the organofluorine compounds contained in the treatment water are decomposed with the microorganisms.
摘要:
The application device for liquid containing micro-nano bubbles generates micro-nano bubbles in a wide size distribution with use of a submerged pump-type micro-nano bubble generator and a spiral flow-type micro-nano bubble generator. A micro-nano bubble generating aid metering pump is controlled by a bubble level meter and a level controller, so that the supply amount of a micro-nano bubble generating aid is controlled in response to the level of bubbles from a fluid level. The supply amount of a micro-nano bubble generating aid is also controlled by a turbidimeter and a controller in response to the turbidity of the liquid in a micro-nano bubble generation tank, while the amount of air supplied to the submerged pump-type micro-nano bubble generator is controlled in response to the turbidity of the liquid. Therefore, the device can produce a large amount of various micro-nano bubbles in a wide size distribution more economically.
摘要:
In the upper part and the lower part of a micro-nano bubble generation section 34 in a micro-nano bubble bathtub 1, two kinds of micro-nano bubbles different in a size distribution are generated by first and second micro-nano bubble generators (submerged pump-type micro-nano bubble generator 2 and spiral flow-type micro-nano bubble generator 10) of two kinds, so that bathtub water containing micro-nano bubbles in a wide size distribution can be produced in a large amount. Some of the water containing micro-nano bubbles generated in the lower part is thrown into the first micro-nano bubble generator (spiral flow-type micro-nano bubble generator 10) in the upper part, so that the spiral flow-type micro-nano bubble generator 10 can generate micro-nano bubbles in a smaller size. Therefore, in this bathtub, micro-nano bubbles abundant in size and large in amount can be produced economically.
摘要:
A water treatment equipment has a raw water tank as a mixing section, a micronanobubble generation tank, a floatation tank, and a treated water tank. Waste water as treatment water is introduced into the raw water tank and mixed with the water containing micronanobubbles produced by the micronanobubble generation tank. Thereafter, the waste water, as treatment water, is introduced into a lower mixing section of the floatation tank from the raw tank by a raw water tank pump. Also, treatment water containing fine bubbles is introduced into the lower mixing section from a pressure tank. Therefore, the micronanobubbles is mixed with the fine bubbles in the lower mixing section of the floatation tank, thereby almost all the suspended matter in the treatment water is surfaced. Thus, the water treatment equipment enhances separatability of suspended matter.

摘要:
In a bioreactor, a culture solution derived from a cultivation tank is separated into bacteria cells and filtrate by a bacteria cell filter. The filtrate is introduced from the bacteria cell filter into a micro-nano bubble generation tank where micro-nano-bubbles are mixed with the filtrate. The filtrate containing micro-nano-bubbles is returned to the cultivation tank to activate the microorganisms therein, so that a biological reaction time is reduced by the activated microorganisms.

Drainage water containing an organofluorine compound is introduced into a raw tank (1) and then filtered through a filtration device (4). Next, a microorganism, a micro-nanobubbling auxiliary agent and a nutrient are added thereto in a first transit tank (5) while micro-nanobubbles are generated thereinto by a micro-nanobubbling machine (7), thereby giving treated water. This treated water is then fed into an active carbon column (14) and then the above-described organofluorine compound contained in the treated water is decomposed by the microorganism as described above.
