Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to an integrated water treatment device.

[0002]

[Prior art]

 In the conventional technique, each device in the processing process is independent. Biochemical oxygen demand and biological treatment to reduce chemical oxygen demand were affected by temperature and climate changes. It took a lot of time to collect sludge by using the sedimentation method.

[0003]

[Problems to be solved by the device]

 The objective is to provide a device that integrates all processes and can be treated without being affected by climate change, and that sludge can be easily treated by floating and scraping it with a fine bubble generator.

[0004]

[Means for Solving the Problems]

 The sludge flotation tank 1 is equipped with an injection tank 2 on the upper side surface, and an agitator 3 and a reaction tank 4 are mounted on the injection tank, and an outflow pipe 5 is connected from the reaction tank to the sludge flotation tank. The fine bubble generator 6 is installed, and the air supply pipe 7 is connected from the fine bubble generator to the lower part of the sludge floating tank. A flotation sludge scraping machine 8 is installed on the upper surface of the sludge flotation tank. A scrape sludge storage tank 9 is attached to the upper part of the front surface of the sludge flotation tank, a discharge pipe and a valve 10 are provided from the bottom of the scrape sludge storage tank, a high speed stirring tank 11 is arranged below, and a high speed agitator 12 is installed. A sludge flotation plate 13 is installed in the sludge flotation tank, and the rear part is partitioned by a partition plate 14 to form a treated tank 15. A discharge port 16 is formed in the upper part, a groove 17 is formed in the center of the bottom surface, and a settling sludge drain port is formed in the rear part. It is an integrated water treatment device provided with 18.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Raw water and concentrated minerals are mixed in an injection tank 2, stirred by a stirrer 3, passed through a reaction tank 4, and then a flocculated liquid is flown into a sludge floating tank 1 through an outflow pipe. The air generated by the fine bubble generator 6 is sent to the sludge floating tank. The sludge that has been floated under pressure is scraped off by the floating sludge scraper 8 and scraped into the sludge storage tank 9. The accumulated sludge drops into the high-speed agitation tank 11 by opening and closing the valve 10 provided at the bottom of the storage tank, and aerobic anaerobic bacteria are added to the sludge at a high speed to agitate the sludge at a high speed to remove sludge containing heavy metals. Detoxify.

2 and 3 release the flocculated liquid and pressurized air into the sludge flotation tank 1, and the sludge that has been slid is lifted by installing a sludge floating plate 13. make it easier. The bottom surface of the sludge flotation tank was inclined toward the settling sludge outlet 18, and a groove 17 was formed in the center of the bottom surface to facilitate the removal of harmless settling slag. The rear part of the sludge floating tank is partitioned by a partition plate 14 to form a treated tank 15, which is discharged from the upper rear surface.

[0008]

[Effect of the invention]

 The treated sludge can be reused as compost. Treated water will be reusable. The integrated type made it easier to manage.
