摘要： PURPOSE:To facilitate effective sewage treatment by drying sewage sludge, treating the dry sludge with a dilute aqueous acid solution to dissolve heavy metals, and separating the treated sludge from the solution. CONSTITUTION:When sewage sludge is dried, not only its water content is decreased but also a solid contained in the sludge, strongly hydrophilic colloid, is converted into a hydrophobic solid during heat-drying. The sewage is then treated with a dilute aqueous acid solution, e.g. 0.8-1.0 N nitric acid solution. In this treatment, 1 pt.wt. of the dry sludge and 5-10 pts.wt. of the acid solution are placed in an appropriate vessel, and the mixture is agitated for 10-30min. The sludge from which heavy metals are dissolved out, after being washed with water, is separated from the solution by filtration etc., and is then heated if necessary. For example, when nitric acid is used, heavy metals are removed from the sludge in large percentages: cadmium, about 80%; lead, about 95%; arsenic, about 95%, respectively.

摘要： PURPOSE:To make manufacturing cost, installation space, and running and maintenance cost of an activated-sludge treatment apparatus advantageous by communicating the middle parts of a higher tub and a lower tub and bottom parts of the higher tub and the lower tub respectively with pipes tilting downward and setting a wastewater supplying inlet and a gas jetting apparatus in the bottom part of the higher tub and setting a treated water discharging outlet in the tip part of the lower tub. CONSTITUTION:Two cylindrical tubs with different height are installed and the higher tub is used as an aeration tank 1 and the lower tub is used as a precipitation tank 4 for precipitating and separating activated-sludge. The aeration tank 1 is made sufficiently high to carry out deep layer aeration treatment and object wastewater of treatment is sent from a wastewater supplying inlet 2 in the bottom part of the aeration tank 1 and aeration is carried out by a gas jetting apparatus 3 and only the aeration-treated water is led to flow the precipitation tank 4 passing a transporting pipe 6 tilting downward and activated-sludge is precipitated in the precipitation tank 4. In the precipitation tank 4, the treated water separated from the activated-sludge overflows out of the discharge outlet 5 in the upper part and the precipitated activated- sludge is returned to the aeration tank 1 passing the returning pipe 7 tilting downward.

摘要： PURPOSE:To carry out solid-liquid separation efficiently by using a biogas formed in anaerobic biological treatment as a pressurizing gas in a pressured floatation method for wastewater which contains difficultly settling solid, and is subjected to anaerobic biological treatment. CONSTITUTION:In anaerobic biological treatment of difficultly settling solid- contg. wastewater, solid-liquid separation is carried out by pressurized floatation method injecting a biogas (a mixed gas of 60% of methane gas and 40% of carbon dioxide), which is formed in anaerobic biological treatment, at about 2-8kg/cm . The biogas injected by pressure becomes free fine bubbles in a normal pressure floatation separation tank, adheres to the surface of the difficultly settling solid, and floats together with the solid, thus the solid is separated. By this method, without causing bad effect on propagation of anaerobic bacteria and no need to buy a costly inert gas, the solid content in material for treatment is decreased efficiently utilizing the advantage of the pressurized floatation method and load of the anaerobic treatment is lessened.

摘要： PURPOSE:To easily separate a floatable solid substance by a method wherein gas is introduced into a liquid to be treated under pressure to be dissolved therein and the liquid to be treated is returned to atmospheric pressure immediately before injected in a three-liquid separating liquid cyclone and the dissolved gas is liberated as fine gas bubbles from the liquid to be treated. CONSTITUTION:A liquid containing a floatable solid substance is treated with a three-liquid separating liquid cyclone 1 to perform solid-liquid separation. A part of the treated water introduced into a treated water storage tank 4 is pumped out by a pump 5 to be introduced into a pressure tank 6 under pressure. Air having air pressure of about 2-10kg/cm is introduced into this treated water under pressure by a compressor 7. This treated water containing the air introduced under pressure is sent to a raw water supply pipeline 9 through a pressure reducing valve 8 and mixed with an about fourfold amount of raw water to be supplied to the cyclone 1 and the dissolved air is liberated herein as fine air bubbles from the liquid to be treated. As a result, a low specific gravity floatable solid difficult to separate heretofore can be easily separated.

摘要： PURPOSE: To provide a cold air supplying method and a cold air apparatus capable of producing a positive flow of cold air, without being influenced by the temperature or humidity of the surrounding atmosphere, and further capable of supplying cold air to a passage. CONSTITUTION: A tower body 5, having an air passage 19 extending in the vertical direction formed therein, is installed vertically at the side part of a passage 1. Water is made to jet out like a shower from the upper part of the air passage 19 to the lower part. An air flow 19 flowing from the upper part to the lower part in the air passage 19 is formed with the shower. Air is sucked from the upper part to the inner part of the air passage 19, and then the air flow 19a is cooled with heat generated by vaporization of water droplets constituting the shower. Then, the air flow 19a flowing in the air passage 19 is made to flow out toward a passage 1.

摘要： PURPOSE: To provide a cold air supplying method for positively producing a flow of cold air, without being influenced by the temperature or humidity of the surrounding air and the like and for blowing only cold air, while separating it from water irrespective of producing a flow of cold air with application of water. CONSTITUTION: Water is injected from the upper part to a lower part within an air passage 25 in a shower form, so as to make an air flow flowing from the upper part to the lower part within the air flow passage 25 with the shower, and concurrently air is sucked from the upper outer part of the air flow passage 25 into the air flow passage and then an air flow 25a is cooled with heat applied when water droplets constituting the shower are gasified. The cooled air flow 25a is flowed upwardly by a sub-air flow passage 37 defined from the lower part of the air flow passage 25 in separate from the air flow passage 25 and, then the air is made to flow from the sub-air flow passage 37 and to flow out of the sub-air flow passage 37.
