Inclined tube floating device for waste water treatment

Abstract

The invention provides an inclined tube floating device for waste water treatment, belonging to the technical field of environmental protection, which is characterized in that: a water inlet is communicated with a whirl mixer arranged at the front end of the device; a mud bucket is arranged on the bottom end of the device body; the device is internally provided with a perforated dredge pipe above which is mounted with a depression area; the depression area is internally provided with an inclined plate and communicated with an absorption area which is arranged at the back end of a buffer area, the absorption area is internally provided with a releasing device of air flotation microbubbles, namely, an activated ploy-oxygen aerator; a mud collecting tank is also mounted on the top end of the absorption area; a catchment area is mounted on the top end of the buffer area, and water collecting equipment is mounted in the catchment area; the upper part of a reaction area is provided with an electric scraping vehicle for removing scum generated by air flotation, and the tail part thereof is provided with an effluent tank which is internally provided with a liquid level regulator; the bottom of the liquid level regulator is provided with a drain pipe. The invention has the beneficial effects of improving treatment effect, evenly mixing medicament and waste water, saving occupied area and materials consumption, increasing air flotation effect, lowering dramatically moisture content of the scum, eliminating dead zones in sludge discharging of devices, optimizing the effluent water quality and reducing moisture content of the sludge.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and is a new type of environmental protection equipment for treating various types of sewage and wastewater. Background technique [0002] High suspended solids and high oil content in wastewater are pollution factors that are difficult to control in wastewater treatment. If not properly treated, it will cause serious pollution to the receiving water body. Air flotation is a more effective method for treating light suspended solids and oily wastewater. According to its working principle, the existing air flotation can be divided into electrolytic air flotation, diffuse air flotation, and dissolved air flotation. The electrolytic air flotation has a good treatment effect and low noise, but its power consumption is too large, and the operation is complicated, and it is prone to failures, which greatly increases the cost of wastewater treatment; the operation of the diffuse air flotation...

AI Technical Summary

Problems solved by technology

The treatment effect of electrolytic air flotation is good, the noise is low, but its power consumption is too large, and the operation is complicated, and it is prone to failure, which greatly increases the cost of wastewater treatment; the operation of air flotation is relatively simple, and the failure rate of equipment is low. However, the bubbles it produces are larger and the treatment effect is poor; the treatment effect of dissolved air flotation is better than that of diffuse air flotation, but its operation is complicated, the releaser is easy to block, the failure rate is high, the noise is large, and it is difficult to operate stably for a long time
