摘要： PURPOSE: To still more lower the water content of a cake and to accelerate the filtering speed thereof, by performing the dehydration of sludge during a time when the pH of the sludge in which a limestone powder is added and mixed is held in an acidic region.
CONSTITUTION: Raw water 1 is sent to a flocculation tank 2 and subjected to flocculation treatment while aluminum sulfate 3 is added to and mixed in said raw water. Subsequently, this water subjected to flocculation treatment is sent to a precipitation tank 4 to be subjected to solid-liquid separation and sludge 5 is sent to a post-treatment process 8 for performing filtration or the like to be treated so as to obtain predetermined water quality while the treated water is sent to a factory or a home. In this case, the sludge 5 from purified water is sent to an acid treating tank 6 where sulfuric acid 9 is added to and mixed in said sludge 5 to adjust the pH thereof to 1W3 and the acidified sludge is subsequently sent to a precipitative precipitation tank 10 to be subjected to solid- liquid separation while the conc. sludge 14 is sent to a dehydration aid adding tank 12 to be mixed with a limestone powder 13 under stirring and the resulting mixture is converted to a cake in a dehydration process 14.

摘要： PURPOSE:To dispense with the pre-treatment of waste ion exchange resin such as pulverization of the resin, to incinerate the resin efficiently and to reduce the quantity of resultant exhaust gas by a method wherein the wet and coarse waste ion exchange resin is mixed with fuel oil and water in the presence of an emulsifier to produce oil drop-in-water three component type stabilized emulsion and the emulsion is burned by spraying. CONSTITUTION:Wet and coarse waste ion exchange resin 12 is mixed with fuel oil 10 and water 11 in the presence of emulsifier 13 to thereby produce oil drop- in-water three component type stabilized emulsion. The emulsion thus produced is transferred from a tank 1 through a pump 2 and burned by spraying it into a furnace 4 through a nozzle 3. Further, an auxiliary fuel is supplied through a pump 5 and a nozzle 6.

摘要： PURPOSE:To further enhance heavy metal-removing efficiency, by adding orthophosphoric ion-forming substance only or in company with a flocculant to the titled liquid and then adjusting the pH value of the liquid, to remove heavy metals from the liquid. CONSTITUTION:Substance, e.g. orthophosphoric acid or its alkali metal salt, which will form an orthophosphoric ion in a heavy metal ammine complex-contg. liquid, is added to the liquid. A flocculant in company with one or more kinds of the substances may be added to the liquid. In this case, the flocculant may be added as a liquid mixed with the substance. The flocculant is preferably one or more of sulfates, chlorides or the like of Fe, Al and Ca, e.g. FeCl3, Al2(SO4)3 and CaCl2. When the concentration of the heavy metal ammine complex is low, said conjunct use is desirable. After the liquid is mixed with these additives, the liquid is adjusted at a neutral pH level by addition of a mineral acid or alkali. Consequently, the heavy metals are converted into an insoluble state and precipitated. The precipitated heavy metals are separated from the liquid.

摘要： PURPOSE:To provide a heavy metal adsorbent capable of adsorbing all types of heavy metal ions by a method wherein a natural or synthetic high-molecular material contg. carboxyl gp. or carboxylate ester gp. in the molecule is reacted with hydrazine. CONSTITUTION:To a natural high-molecular material such as lower acids or fumic acid, or a synthetic hig-molecular material such as poly(meth)acrylic acid and poly (meth)acrylate which contains -COOR (where in R=H and/or alkyl gp.) in the molecule, a proper amount of hydrazine or its hydrate, or hydrazine carbonate is added and mixed to undergo the reaction. The process provides a heavy metal adsorbent having enhanced adsorbing properties. Particulary, complex ions such as Cr2O7 which can not be adsorbed by a conventional nitrofumic acid-based adsorbent can be adsorbed and removed by this adsorbent with a high removal ratio.

摘要： PURPOSE:To perform the dust removal of gas contg. great quantities of steam by sending the gas in the order of the first venturi scrubber, a gas cooler and the second venturi scrubber and treating it. CONSTITUTION:A high-temp. radioactive exhaust gas G1 sent from an incinerator is cooled in a underwater bubbling type scrubber 1 and both the cooling of the above-mentioned gas G1 and the primary removal of the contained minute grain are performed herein. Then the radioactive gas G2 contg. the great quantities of steam which are produced in the water washing is sent too the first venturi scrubber 2 to perform the secondary removal. Successively the radioactive exhaust gas G3 having a state saturated with steam discharged therefrom is sent to a gas cooler 4 via the first mist separator 3. Therein the grain size of the steam is increased while keeping the minute grain which is not removed in the scrubber 2 as a nucleus. Therefore the minute grain incorporated in the gas G5 sent to the following second venturi scrubber 5 can be effectively removed.

摘要： PURPOSE:To selectively concentrate valuables from an aqueous solution containing inorg. salts and low MW org. valuables, by subjecting an aqueous solution to be treated to membrane separation treatment, which uses a separation membrane or which the salt exhaustive ratio under operation pressure of osmotic pressure of less of said solution is specific value or more, under operating pressure of osmotic pressure or more. CONSTITUTION:A separation membrane having separation capacity capable of obtaining a salt exhaustive ratio of 5% or less when membrane separation treatment is applied to an aqueous solution to be treated under operation pressure of osmotic pressure or less of said aqueous solution, for example, a loose reverse osmosis membrane or an ultrafiltration membrane of a low fractionation MW grade is used. By using this separation membrane, the aqueous solution to be treated is subjected to membrane separation treatment under operation pressure of osmotic pressure or more of said aqueous solution and an untransmitted solution is recirculated to a raw solution tank during treatment and diluting water is added to said tank to hold the liquid level of the raw solution tank to a constant level. By this method, because inorg. salts are transmitted but org. valuables with a MW of 1,000 or less are not transmitted, valuables can be selectively concentrated and recovered.

摘要： PURPOSE:To subject the sludge in a night soil purifying tank to concn. and volume reduction in a pretreatment to save energy in a final treatment by combining the respective stages of the 1st flocculation and solid-liquid sepn., dehydration, biological treatment, the 2nd flocculation and solid-liquid sepn., flocculation, membrane sepn. and incineration. CONSTITUTION:A flocculating agent is added to the purifying tank sludge collected in a storage tank 1 in the 1st flocculation stage 2 so as to form flocculate. The sludge is separated to the flocculate and sewage with a tilting screen device in the 1st solid- liquid sepn. stage 3; the former is dehydrated with a dehydrator in a dehydration stage 4 and the sewage is fed together with the sewage from the stage 3 to a biological treatment stage 5. The sewage treated bioligically in said stage is treated in the same way as in the stage 2 in the 2nd flocculation stage 6 to form flocculate. The flocculate is settled in the 2nd solid-liquid sepn. stage 7 and is returned to the tank 1, and the supernatant is fed to a flocculation and filtration stage 9. A flocculating agent is mixed with the sewage and the sewage is filtered in said stage; the filtrate is subjeted to a reverse osmosis treatment in a membrane sepn. stage 11 and is separaed to permeated water and concd. water. The latter is treated together with the dehydrated cake from the stage 4 in an incineration stage 12, etc.
