Embodiment Construction

[0016] Such as figure 1 The shown device for reducing the content of nitrogen compounds in water has a container made of water-resistant material FRP; the top of the container is open 11; the lower part of the shell 9 of the container has a waste water inlet 1, and the bottom of the shell 9 has an ozone aeration inlet 2 .

[0017] A trumpet-shaped case 6 is connected to the upper part of the shell 9, the lower part is large and the upper part is small, the lower part is seamlessly connected with the inner surface of the shell 9, and the upper part has a bubble outlet 7; the upper part of the shell 9 is lower than the bubble outlet 7. Exhaust gas waste liquid outlet 10. On 9 sides, below the trumpet-shaped casing 6 or on the casing, there is a reclaimed water outlet 5 with a diameter smaller than the waste water inlet.

[0018] The caliber of the bubble outlet 7 is 1 / 2-1 / 10 of the caliber of the opening 11, and the caliber of the bubble outlet 7 is 5-50 times of the caliber o...

Abstract

The invention discloses a device for reducing the content of nitrogen compounds in water. The device is provided with a container made from a water-resistant material; an opening is formed in the top of the container; a waste water inlet is formed in the lower part of a shell of the container, and an aeration inlet is formed in the bottom of the shell; a trumpet-shaped housing is connected with the upper part in the shell, and a bubble outlet is formed in the upper part of the trumpet-shaped housing; the aperture of the bubble outlet is 1 / 2-1 / 10 that of the opening, and is 5-50 times that of the aeration inlet; a recycled water outlet is formed under the housing or in the housing. The aeration inlet is connected with a venturi jet pipe, so that ozone can quickly enter the device, and less ozone is consumed. The device is simple in structure and smaller in size, is capable of removing waste gas and part of solid waste particles which are dissolved in waste water, and is higher in waste water purification treatment efficiency. After the device is used, a great deal of waste water can be purified into recycled water for recycling, so that water resources are saved.

Description

technical field [0001] The invention relates to a waste water treatment device. Background technique [0002] Aeration devices are often used in wastewater treatment. The conventional aeration is air or waste gas, so that the sewage in the wastewater is not suitable for sedimentation, which is beneficial to purification treatment. However, its entry and exit methods are very random, resulting in an unsatisfactory purification effect. [0003] The invention with the application number 2007100529462 discloses a combined method and device for purifying aquaculture wastewater. It is completed by the following process: After precipitation, the breeding wastewater is filtered, soaked through dead wood for anaerobic nitrogen removal treatment; then soaked through bamboo charcoal and limestone for aerobic gas blast treatment; after internal electrolysis treatment , and finally complete purification and discharge after adsorption treatment. Although the device has purification tre...
