A detailed explanation will be omitted since the same thing will be used. In FIG. 1, 41 is a water inlet, 42 is a water outlet, and 43 is a third recovery section.

仕切板２０の小穴２０ａを経て上部の第一回収部
２２に溜まる。 Next, the operation of this device will be explained. First, when wastewater passes through the electrode part 17, pollutants are decomposed by the oxidation action at the anode 17a and the reduction action at the cathode 17b, and also by the decomposition of aluminum ions and water generated from the anode 17a. Oh
The aluminum hydroxide reacts with the ions to produce aluminum hydroxide, and while the wastewater is rising through the riser pipe 13, the decomposed pollutants are adsorbed and coagulated by the coagulation action of the aluminum hydroxide. Furthermore, the generated hydrogen gas is also adsorbed, and the apparent specific gravity of the pollutants becomes lighter.
It becomes a flock and floats to the top of the tank body 11.
Since a baffle plate 21 is provided at the upper part of the tank body 11, the flow velocity here becomes extremely slow, and most of the floating pollutants are captured by the baffle plate 21 and flow through the small hole 20a of the upper partition plate 20 to the upper part. It accumulates in the first collection section 22 of.

れる。 Unreacted substances, insufficiently decomposed substances, or pollutants that are not collected here due to small particles and insufficient buoyancy enter the downcomer pipe 14 and descend, and further reaction continues until reaching the electrode section 18, and some of the pollutants are The remaining water rises against the flow of wastewater and reaches the first recovery section 22, but the remaining water reaches the electrode section 18, where electrolysis is performed again to promote decomposition and generate gas, and then the wastewater is discharged to the water outlet. 16, the water is sent to the second reaction tank 2 via the water inlet 33.

見掛の比重の大きいフロツクとなつて上部の第二
回収部３５に浮上して溜まる。 In the second reaction tank 2, aluminum ions are generated from the aluminum spheres 32 by the electrolyte contained in the wastewater, and due to the adsorption action of these aluminum ions, hydroxides of other metals contained in the wastewater as well as aluminum hydroxide are generated. The particles are aggregated and become in a state where they easily adsorb gas, and the adsorbed gas turns them into flocs with a large apparent specific gravity, which floats and accumulates in the upper second recovery section 35.
こうして廃水中の汚濁物質の80〜90％は除去さ

４、水入口４１を経て第三反応槽３に送られる。

に溜まる。 In this way, 80 to 90% of the pollutants in the wastewater are removed, but the wastewater containing the remaining pollutants is removed from the water outlet 3.
4. The water is sent to the third reaction tank 3 through the water inlet 41.
Since graphite is used for both the anode and cathode electrodes of the third reaction tank 3, metal ions are not generated here, only gas is generated due to electrolytic action, and pollutant particles are not involved in the subsequent reaction. It adsorbs gas while condensing and floats to the third recovery section 43.
It accumulates in

In addition, the flocs of pollutants that have floated and separated in the respective recovery sections 22, 35, 43 are removed from the valves 51, 52,
53 is opened from time to time using a timer or the like to collect the oil in the oil recovery tank 4 and process it as appropriate.

を用い、これを15ppm程度添加する。 If the wastewater treated with this device is bilge,
Since seawater containing salt is mixed in, in the above reaction, aluminum ions react with the sodium ions of sodium chloride to produce aluminum chloride, which reacts with the hydroxyl groups produced by water decomposition. Activated aluminum hydroxide is produced, but if the wastewater does not contain seawater, it is necessary to add an electrolyte as appropriate. In addition, if a surfactant is contained in wastewater, the oil will be emulsified by the action of the surfactant and will not be easily decomposed, so if the amount of surfactant exceeds about 100 ppm, It is necessary to add appropriate additives to destroy this surfactant and release oil. The additive tank 6 and mixer 7 are used in such cases. 54 indicates an additive solution. As the additive used for the purpose of destroying the surfactant, for example, a mixture of aluminum chloride and caustic soda and calcined mixture is used, and this is added in an amount of about 15 ppm.

で充分であつた。 This device has the above-mentioned configuration, and each of the reaction tanks 1, 2, and 3 uses a cylinder with a diameter of 300 mm, the height of the reaction tanks 1 and 3 is selected to be 1800 mm, and the second reaction tank 2 is The porosity between the aluminum balls 32 within the
~30%, the size of the mutually opposing parts of electrode parts 17 and 18 is 150 x 200 mm, and the distance between the anode and cathode is 10
mm, and the DC voltage applied to this electrode part is 6~
At 8V, wastewater can be treated at a rate of 1.5 to 1.8 tons per hour, and there are
We were able to reduce oil content from 300ppm, 200ppm, and 100ppm to below 15ppm, 7ppm, and 1ppm, respectively. Therefore, if this device is used in combination with a conventional oil/water separator, it can easily pass even strict standards. In addition, the apparatus of this embodiment uses the reaction vessels 1 and 3 in a vertically elongated manner, and furthermore, a vertical partition plate 12 is provided inside the apparatus to lengthen the path of the waste water, so that the installation space is effectively utilized and the above-mentioned problems can be achieved. The installation area of a device with processing capacity is only 1 m 2
That was enough.

Therefore, it is possible to easily obtain a device that is most suitable for use on a ship or the like where such a device is desired.

置。[Claims] 1. Wastewater containing emulsified oil is flowed between opposing electrodes, one of which uses an electrode that generates aluminum ions, for electrolytic treatment, and pollutants are decomposed by oxidation and reduction at the electrodes. and a first reaction tank that adsorbs and aggregates the decomposed pollutants using the coagulation effect of aluminum hydroxide, and adsorbs and floats the generated gas, and the first reaction tank is placed in the gap between the filled aluminum spheres. A second reaction tank is used to flow wastewater through which fine metal hydroxides coagulate and grow due to the adsorption action of aluminum ions, promote gas adsorption, and float and separate. A treatment device for oil-containing wastewater characterized by sequentially connecting a third reaction tank in which the wastewater that has passed through the reaction tank is allowed to flow, and the gas generated by electrolysis is adsorbed onto remaining pollutants and separated by flotation.
