In practice, add alum, iron (III) chloride, polyaluminum chloride, etc. to lime based on lime and add it to the polluted water, or mix these in advance and add to the polluted water, then stir them well. It is possible to separate the purified clear water within a few minutes by rapidly coagulating and sedimenting the mud, sand, impurities, etc. that are dissolved or suspended in the polluted water by the synergistic action of these chemicals. it can. 95% of heavy metals can be removed, and residual ammonia and nitrogen in the human waste treatment process can be neutralized and eliminated. Even if the treated polluted water contains oil or soap, the oil and soap can be removed by adding and mixing these chemicals. If calcium-containing substances such as lime or quick lime and alum or iron chloride are alternately adjusted in appropriate amounts and mixed in polluted water and stirred well, within 1 minute due to the synergistic effect of the agglomeration and reaction of each substance The mud settles to the bottom from the polluted water, and the water is purified to clear water like clean water within 3 minutes. The use of this calcium-containing substance and alum or iron chloride,
It has a precipitation separation effect not only on polluted water but also on blue water or red tide.In addition, a large amount of a calcium-containing substance is added to this polluted water, blue water or red tide, or in addition to this, potassium permanganate, ClO. When 2 and / or chlorine type bactericides are used at the same time, in addition to the coagulation-sedimentation treatment, bactericidal, deodorant and decolorizing effects are exhibited. As flocculants, in addition to lime and quicklime, lypon (trade name of anion activator manufactured by Lion Oil & Fat KK); fossil shell; powder of shellfish or shellfish; powder of coral, coral ginger; fish, animals and plants or plankton Calcium-containing carcasses, or calcium-containing rocks, and other substances that contain large amounts of CaO exhibit a cohesive effect.

As an additive mixed agent other than the calcium-containing substance, alum (aluminum sulfate etc.)
There are iron (III) chloride, iron (II) sulfate, (III), copper chloride, potassium sulfate, polyaluminum chloride and the like.
The organic coagulant aids include sodium polyacrylate, partially hydrolyzed salts of polyacrylamide, etc. as its anionic system, polyacrylamide, polyoxyethylene, etc. as its nonionic system, and its cations. Examples of the system include polyethyleneimine, quaternary ammonium salts, and other polymer flocculants. These auxiliaries are used as a simple substance and / or a mixture thereof by mixing with a calcium-containing substance such as lime and quicklime, and further, ClO 2 , potassium permanganate, and / or chlorine as a bactericide are appropriately used. It is used as a mixture, or the bacterium is mixed and stirred. The purification treatment object of the present invention is tap water, sewage, human waste, sewage, turbid water, industrial drainage, Aoko or Akashio, food factory drainage, meat processing plant drainage, fish processing plant drainage, livestock drainage, domestic drainage, and River construction, dam construction, tunnel construction, tunnel construction,
It is drainage or recycled water from high pressure water jet cutting work, chisel work, building work, underpass work, etc. In the purification treatment of such wastewater, the present invention can purify a large amount of polluted wastewater in an extremely short time when combined with an appropriate device, machine or septic tank. Iron chloride, aluminum chloride, calcium carbonate, ferric sulfate, aluminum sulfate, together with calcium-containing substances,
When simple substances such as sodium carbonate, sulfuric acid, hydrochloric acid, zeolite, diatomaceous earth, sodium silicate, etc. or a mixture thereof are added to the polluted water and mixed and stirred, the water becomes completely transparent and the mud in the polluted water is rapidly separated. Settles on the bottom of the water. Therefore, it is convenient to use these substances by appropriately mixing them. Some of these inorganic substances are used as soil conditioners, and some are also effective as plant nutrients (flocculants, flocculants, etc.). Since some of them have deodorant effects (acid, alkali, etc.), sludge precipitated and deposited using these substances can be used as it is as a fertilizer. In addition, the substances containing the above nutrients are added to and mixed with wastewater during purification of contaminated water, blood collection of human waste, blood storage of animals, and water treatment of various wastes, and mixed with this. ) And other fermenting bacteria are added and well stirred to promote purification of polluted water and ferment to obtain fully fertilized fertilizer, so when using this as fertilizer for vegetables, fruits, rice, and other plants. Can get twice as much harvest as normal fertilizer. Next, add a calcium-containing substance such as lime or quick lime as a coagulant to a large amount of polluted water and alum or iron (III) chloride as another agent, or add another coagulant in an appropriate combination. Or, by mixing two or more kinds of calcium-containing substances, calcium-free flocculants, coagulant aids, etc. into the polluted water and stirring well, the mud and clear water are rapidly separated. An example of a device of the present invention that can be used will be described with reference to the drawings. As shown in FIG. 1, a screw 4 which is rotated by a shaft 3 connected to an external motor 2 is installed in the water conduit 1 into which polluted water is introduced, or as shown in FIG. The water flow is rotated in the water guiding pipe by attaching a screw 5 or by attaching a suitable number of protruding spiral strips or folds 6 to the inner wall of the water guiding pipe 3 as shown in FIG. Above the water conduit, a metering device-equipped device 7 for constantly supplying a constant amount of a coagulant or other chemicals in proportion to the amount of water is installed. From this device, through a pipe 8, an appropriate amount of a calcium-containing substance and iron chloride, alum, polyaluminum chloride or the like is added to 1 ton of contaminated water, and the contaminated water flowing in the introduction pipe is stirred and mixed for reaction. , Coagulate mud and impurities contained in polluted water from water. Thereafter, a rotary separation settling filter, thickener, clarifier, settling tank, filtration tank, and other suitable separation settling filter are used to separate mud and water from the contaminated water to recover purified water. As one of the methods, after the coagulant and the like are mixed, the polluted water discharged from the water pipe is introduced from the pipe 10 shown in FIG. , Further filter the separated water with filter 12,
Alternatively, a cyclone is provided for further separation. Further, as shown in FIG. 5, a stirring rotary type separation / filtration device 9 having a cyclone-like shape is provided, into which polluted water mixed with a coagulant is introduced from a water pipe 1, and the water inside the device is introduced in the middle stage thereof.
