In the upper part and the lower part of a micro-nano bubble generation sectionin a micro-nano bubble bathtub, 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 generatorand spiral flow-type micro-nano bubble generator) 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) in the upper part, so that the spiral flow-type micro-nano bubble generatorcan 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.

Device and method for increasing blood flow and insulin-like growth factor

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

Drainage water-treating method

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.

Biological reaction method and bioreactor

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.

Water treatment equipment

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.

Manufacturing device and application device for liquid containing micro-nano bubbles

A first reaction/adjustment tank has a lower portion containing a calcium carbonate mineral, an upper portion containing a calcium carbonate mineral and a plastic filler, and an air lift pump for circulating waste water from the lower portion to the upper portion. Exhaust gas is introduced into a space. A second reaction/adjustment tank has a lower portion containing a calcium carbonate mineral and charcoal, and an upper portion containing charcoal and a plastic filler. Waste water circulates sequentially through the lower and upper portions of the first reaction/adjustment tank, and the lower and upper portions of the second reaction/adjustment tank. Exhaust gas circulates sequentially through the upper portion of the first reaction/adjustment tank and the upper portion of the second reaction/adjustment tank.

Method for treatment of waste water and/or exhaust gases containing

Apparatus for treatment of waste water and/or exhaust gases containing

A waste water treatment apparatus is provided which can treat a high-concentration waste water containing persistent chemical substances including nitrogen and surfactant simultaneously with small amount of exhaust gases and is yet simple in construction. The apparatus has a first bioreactor having a lower portion including an inflow pipe for admission of waste water to be treated and aeration means, and an upper portion packed with vinylidene chloride fillers; a second bioreactor including a filler-packed portion packed with charcoal and calcium carbonate fillers; and an exhaust gas introduction diffuser for directing exhaust gases generated in an uppermost portion of the first bioreactor into the filler-packed portion. The water under treatment is anaerobically treated in the lower portion and is subjected to aerobic treatment and also to anaerobic treatment in the upper portion. Further, in the second bioreactor, the water under treatment is again aerobically treated and, at the same time, the exhaust gases from the first bioreactor are also aerobically treated.
