摘要： PURPOSE:To effectively regulate pH value of stabilizer liquid as well as inactivate it by contacting denaturated stabilizer liquid containing cement with CO2 gas. CONSTITUTION:When a stabilizer liquid prepared by dispersing and dissolving a clay mineral such as bentonite and a water-soluble polymer in water is denaturated with cement, the stabilizer liquid is housed in a tank 1 and contacted with CO2 gas through a nozzle 2 from a CO2 source 4. In this case, CO2 gas is supplied through a solenoid valve 9 and a flow meter 10, whereby making the regulation of pH of the stabilizer liquid easier and also permitting the precipitation of CaCO3 inactivation of CO2 to be performed effectively.

摘要： PURPOSE:To effectively clean excess water discharged to the outside of a reclamation site area for preventing the pollution of water in and around rhe reclamation site by a method in which supernatant water is discharged by overflowing it in a water collection dam of a length enough to make an overflowing load 50m /m.hr or less. CONSTITUTION:Dredged soil and sand mixed with the sea water coming into a reclamation site 2 is natually separated by settlement, and the excess water as the supernatant water is directed into an excess water trench 13 by overflowing cross the first water collection dam 10 (an overflowing load of 50m /m.hr or less) and then sent through a communication trench 14 into a settlement basin (a surface load of 0.31m /m .hr or less an average flow rate of 16cm/min or less), where the water is subjected to a settlement treatment. The supernatant water overflows cross the second water collection dam 11 (an overflowing load of 50m /m hr or less) and then is discharged from an outlet port 12 into the sea 1. To promote the settlement of suspended substances in the settlement basin 9, a baffle plate 15 and rectifying canvases 16 and 17 are provided to accelerate the formation of flocs.

摘要： PURPOSE:To remove Cr(VI) effectively by adding metallic salt to neutral or alkaline waste water to form hydroxides, and reducing formed hydroxides to cause precipitation of Cr(III) hydroxide, then separating said hydroxide. CONSTITUTION:A solution of Fe(II)Cl2 for forming Fe(II) hydroxide is injected from a vessel 2 through a pump 3 into waste water transported by a transporting pipe 1, and mixed with the waste water by a static mixer 4. The amt. of Fe(II)Cl2 to be added is adjusted to 4.5mol ratio of Fe(II)Cl2 to the amt. of Cr(VI) in the waste water. After mixing, polyaluminum chloride is added as a flocculating agent from a vessel 5 through a pump 6 to the waste water in an amt. to obtain 20ppm concn. in the waste water. The waste water is then transported through a transporting pipe 1 to a settling and separation tank 7, where solid matters formed in the waste water such as Cr(III) hydroxide and ferric hydroxide are settled as settled sludge 8 and separated.

摘要： PURPOSE:To improve the bonding between a steel part and concrete by a method in which current is flowed between an anode inserted into a stabilizer liquid and a custom-made steel part as a cathode immediately before the placement of concrete and clay particles adhered to the steel part are removed. CONSTITUTION:An iron bar cage 5 is set in an excavated trench 1, and then an electrode 7 is inserted into the cage 5 immediately before the placement of concrete. The electrode 7 is connected to the plus side of an external DC power source device 8 and a partition iron plate 3 and cross bars 4 are connected to the minus side of the power source device 8. Current of 5A/m or more is then flowed between both the electrodes so that clay particles adhered to the iron plate 3 and the cross bars 4 are separated due to the formation of the film of water as a diaphragm between iron bars 3 and the cross bars 4. Afterwards, concrete is placed and hardened.

摘要： PURPOSE:To detect the concentration of excess CO2 gas extracted and recovered in air quickly, and to reduce the quantity of CO2 gas diffused into atmospheric air by diffusing air into a reaction liquid in an airtight vessel and extract excess CO2 gas in the liquid. CONSTITUTION:A CO2 gas-added CO2 gas reactive liquid is housed in a chamber constituted in an airtight manner, and air is diffused into the liquid. Bubbles are generated in the liquid, and excess CO2 gas is extracted together with the bubbles. The concentration of CO2 gas in aerated and recovered excess CO2 gas-mixed air is detected continuously. The optimum quantity of CO2 gas to be added to the liquid is determined, and the loadings of CO2 gas is feedback- controlled optimally in response to the change of the concentration of CO2 gas detected. The CO2 gas is added to the CO2 gas reactive liquid at that time, both CO2 gas and liquid are mixed by a mixer 2, contact efficiency is improved, and the reactive liquid is pressured by agitation. Accordingly, the reaction of the liquid and CO2 gas is accelerated, thus reducing the quantity of an unreacted CO2 gas to be added.

摘要： PURPOSE:To permit the work of highly dense reclamation by a procedure in which dredged soil and sand with excessive water are delivered to a reclamation site, the excessive water in the form of supernatant water is discharged by overflowing it over a water-collecting sluice of a length corresponding to less than a given value of overflowing load, and then the soil and sand are settled for reclamation. CONSTITUTION:A reclamation site 2 is surrounded by a concrete revetment and a soil dam 4, and its circumference is provided with a transportation pipe 5 through which soil and sand with excessive sea water, dredged by a pump dredger, are flowed. Also, the reclamation site 2 is provided with a partition wall 7 made of canvas to divide the site into two, and a coagulating sedimentation basin 9 is provided in one, on the opposite side of the discharge port 6 of the transportation pipe 5, of the reclamation site divided into two sections by the partition wall 7. The sedimentation basin 9 is provided with the first water collection sluice 10 through which the supernatant water of the dredged excessive water in the reclamation site 2 is overflowed and the second water collection sluice 11 through which the supernatant water in the sedimentation basin 9 is overflowed along the revetment 3. In this case, the lengths of both the water collection sluices 10 and 11 are set up to such an extent that the overflowing load of the supernatant water is 50m / m.hr or less.
