摘要:
Water (23) that contains micro-nano bubbles generated in a micro-nano bubble generation tank (6) is introduced and treated in a charcoal water tank (11) which is filled with a charcoal (15) and in which an air diffusing pipe (12) is placed and thereafter introduced and treated in a membrane device (21). Thus, activities of microorganisms propagating in the charcoal (15) are increased by the micro-nano bubbles, markedly increasing ability of decomposing organic matters in the water. Therefore, a clogging phenomenon due to the organic matters can be prevented by reducing organic loads on the membrane device (21). Moreover, a very small amount of alcohols or salts are added as a micro-nano bubble generation aid to the micro-nano bubble generation tank (6), improving an incidence rate of the micro-nano bubbles. In the case, since the alcohols and salts are easily decomposed by the charcoal water tank (11) and easily removed by the membrane device (21) in the subsequent stage, no bad influence is exerted on the membrane device (21).
摘要:
In waste water treatment apparatus and method, a mineral mixing tank receives biologically treated water, sludge which is generated by biological treatment, and mineral sludge which contains calcium and so on from a settling tank. A mineral pump returns the sludge and the treated water from the mineral mixing tank to a raw water tank. An air-lift pump circulates treatment water between a reaeration tank having a semi-anaerobic section and a denitrification tank. In circulation of the treatment water between the reaeration tank and the denitrification tank, the semi-anaerobic section alleviates the change of environment for microorganisms and thereby realizes the environment easy to propagate for the microorganisms. The air-lift pump allows the agitation with low energy consumption even when the microorganisms are cultured up to a high concentration thereof.
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:
A calcium carbonate mineral is placed in a lower portion of a second water tank, while sludge precipitated in a sixth water tank is returned to an upper portion. A blower and an air diffusion pipe weakly aerate the lower portion. Thus, an unreacted chemical sludge zone is formed in the upper portion of the second water tank. As a result, the second water tank can execute a primary treatment of fluorine in a waste water by the calcium carbonate mineral, a secondary treatment of fluorine and a primary treatment of phosphor by unreacted chemicals, treatment of surface active agent by microorganisms in a return sludge and reduction treatment of hydrogen peroxide by anaerobic microorganisms in the return sludge. The unreacted chemicals are thus reused, so that the amount of generation of waste can be reduced and concurrently the treatment can be executed with energy conservation.
摘要:
In a third tank, calcium carbonate mineral is filled to react with fluorine in treatment water. Then, generated treatment water containing calcium fluoride is aerated and stirred so that aerobic microorganisms are propagated, by which organic matters are treated. A fourth water tank is to perform treatment of hydrogen peroxide by anaerobic microorganisms in return sludge from a sixth tank, treatment of phosphorus by slaked lime newly added in a small amount, and secondary treatment (advanced treatment) of fluorine that has already been primarily treated in the third tank. In a fifth tank, flocs are coagulated. In the sixth tank, the coagulants are settled and separated so as to be discharged as treated water. Thus, mixed waste water of hydrogen-peroxide- and phosphorus-containing fluorine waste water and organic-matter-containing waste water is treated simultaneously with low running cost and maintenance cost.
