A river sewage treatment device

Abstract

The invention relates to a river sewage treatment device, which includes a plurality of water purification plant cultivation systems arranged between the rivers on both sides, a river bottom oxygen supply system is arranged between adjacent water purification plant cultivation systems, and the water purification plant cultivation system includes Four support frames, the support frame includes a base and a support sleeve connected to the base, a support rod is inserted into the support sleeve; one side of the support rod is connected to a fixed rod, a rotating sleeve is set on the fixed rod, and a traction rope is wrapped around the rotating sleeve. One end of the traction rope is connected to the load-bearing component, the other end of the traction rope is connected to one corner of the sewage treatment net, and the ends of the four traction ropes are connected to the four corners of the sewage treatment net to pull and stretch the sewage treatment net. There are several submerged plants on the sewage treatment net The cultivation unit, the submerged plant cultivation unit includes a base arranged on the sewage treatment net, a plant planting pot is placed in the groove of the base, a screw is connected between the bottom of the plant planting pot and the base, and the two ends of the screw are fastened with fixing nuts. The sustainability of sewage treatment is strong.

Description

technical field [0001] The invention relates to the field of environmental pollution control, in particular to a river sewage treatment device. Background technique [0002] The water pollution of our country's rivers has been quite serious, the main manifestation is "eutrophication". River sewage not only affects the functions of water bodies such as domestic water supply and harms aquatic organisms, but is also causing the demise of the river itself. Reasonable sewage treatment technology must be selected on the basis of feasibility study. The main considerations include: the effectiveness of the technology; the degree of restoration of the water environment; investment and cost, and the effectiveness and cost comparison of possible alternatives. [0003] Basic methods for river water environment restoration: [0004] 1. Control exogenous pollution: controlling exogenous load is the fundamental way to improve the eutrophication of river water. [0005] 2. Dilution and s...

Problems solved by technology

[0011] The above seven traditional river sewage treatment methods basically require a lot of financial and manpower to complete, and their sustainability has yet to be verified. For some small rivers in rural areas or towns, if a large amount of money is not invested in sewage treatment, it is basically It is impossible to complete the work of river purification. The current sewage treatment projects are generally relatively large, and ordinary people cannot complete the work of river sewage treatment.
