Improvement treatment device for black and odorous water in lakes

Abstract

The invention relates to an improvement treatment device for black and odorous water in lakes, the device comprises a flocculating settling bin, a sewage inlet is formed in the middle of one side of the flocculating settling bin, a purified water outlet is formed in the upper portion of the other side of the flocculating settling bin, a flocculent precipitate discharging port is formed in the bottom of the flocculating settling bin, and a precipitate collecting bag is arranged at the flocculent precipitate discharging port in a sleeving mode; a plurality of flexible water filtering strips arefixed in the flocculating settling bin; a sewage inlet of the flocculating settling bin is communicated with a flocculating agent conveying pipe, and the flocculating agent conveying pipe is communicated with a flocculating agent bin; the flocculating settling bin is connected with a floating body; a ducted propeller is mounted in the purified water outlet and is connected with a rotary power device. The device is arranged in lake water, does not occupy land space, can gradually purify surrounding water and pump away sediments, and can be conveniently folded, carried and unfolded for use due to the fact that the related bag body is of a flexible structure.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a device for improving and treating black and odorous water in lakes. Background technique [0002] Water resources are an indispensable and important resource for human life and work. However, due to the continuous acceleration of urban development in my country, some sewage discharges into lakes, causing serious black and odorous phenomena in lakes, which seriously affect the ecology. [0003] In the process of treating black and odorous water bodies, enhanced flocculation in chemical treatment is the most effective one. By spraying flocculants and adopting flocculation sedimentation technology, water particles and soluble toxic substances can be quickly improved through natural coagulation and sedimentation. By migrating and transforming sediments, the health of the water body is gradually restored. However, in the actual process, the cost of spraying flocculants i...

AI Technical Summary

Problems solved by technology

Some flocculants contain copper sulfate, and when the flocculant and other agents are poured in, the water will soon become clear, but the copper ions and other chemical substances in the flocculant will be mixed in the flocculated sediment and settle in the bottom of the water body and in the sludge, which not only affects the The survival of aquatic organisms is destroyed, the water ecology is destroyed, the water body still has no self-purification ability, and the water body will be turbid or black and smelly after a period of time
