Multilayer purification device capable of intelligently positioning and releasing carbon source in water and purification method

Abstract

The invention discloses a multi-layer purification device capable of intelligently positioning and releasing a carbon source in water. The multi-layer purification device comprises a stand column, a first motor is installed at the top end of the stand column, the first motor is connected with a column screw, the lower portion of the column screw is connected with a circular tray, and the circular tray can move up and down along the stand column; a rotatable large gear and a small circular cylinder are installed on the circular tray, a plurality of umbrella ribs are installed on the small cylinder and hinged to a hoop through folding rods, the hoop is arranged on small connecting rods in a sleeving mode, the small connecting rods are installed on the small circular cylinder, and in all the small connecting rods, two symmetrically-arranged small connecting rods are connected with a second motor. The small connecting rod is provided with threads, a nut is fixedly installed in the hoop, and the small connecting rod is matched with the nut. According to the invention, a platform capable of intelligently positioning and putting a carbon source is arranged at the middle lower part, and a plurality of layers of floatable plant platforms are also arranged in an oxygen-enriched area at the upper part of the facultative pond, so that emergent aquatic plants and submerged plants can be planted to further improve the removal efficiency of pollutants.

Description

technical field [0001] The invention relates to a multi-layer purification device and a purification method capable of intelligently positioning and releasing carbon sources in water, belonging to the field of ecology. Background technique [0002] At present, the ecological pond technology is one of the commonly used technologies in the tail water treatment of the upgrading sewage plant. The facultative pond in the ecological pond is often used because of its long hydraulic retention time and the characteristics of both aerobic and anoxic regions. The upper, middle and lower areas of the facultative pond have different oxygen content. The area with high oxygen concentration is suitable for the growth of water purification plants, and the area with low oxygen concentration is suitable for denitrification reaction to remove nitrogen. The tail water of sewage treatment plants is generally low carbon nitrogen ratio sewage. The lack of carbon sources makes it difficult to maint...

AI Technical Summary

Problems solved by technology

At present, solid carbon sources in facultative ponds are mainly thrown into the bottom of the pond directly. The accumulated carbon sources cannot fully contact with the water body, the diffusion effect of carbon sources at the bottom of the pond is not good, and the efficiency of being used by microorganisms is not high. It is difficult for the carbon source to be replaced regularly, resulting in waste or even secondary pollution of the water body

At present, the CN211338949U patent has made some improvements in the way of adding agricultural solid slow-release carbon sources and increasing the contact area with water bodies, but there are still problems that need to be salvaged repeatedly, and the actual contact between carbon sources and water bodies is limited to the box. Internal problems, denitrification efficiency is seriously affected
