River sewage treatment device

Abstract

The invention relates to a river sewage treatment device. The river sewage treatment device comprises a plurality of water purification plant cultivation systems arranged between two lateral river channels, wherein a river bottom oxygen supplying system is arranged between the adjacent water purification plant cultivation systems; the river bottom oxygen supplying system comprises four supportingframes; each supporting frame comprises a base and a supporting sleeve connected with the base, and a supporting rod is inserted into each supporting sleeve; a fixed rod is connected with one side ofeach supporting rod and a rotary sleeve sleeves each fixed rod; a traction rope is wound on each rotary sleeve; one end of each traction rope is connected with a loading assembly and the other end ofeach traction rope is connected with one corner of a sewage treatment net; the end parts of the four traction ropes are connected with four corners of the sewage treatment net and the sewage treatmentnet is dragged and stretched; the sewage treatment net is provided with a plurality of submerged plant cultivation units; each submerged plant cultivation unit comprises a base arranged on the sewagetreatment net; a plant planting pot is arranged in a groove in each base; a screw rod is connected between the bottom part of each plant planting pot and the corresponding base; fixed screw caps arefastened at two ends of each screw rod. The river sewage treatment device has strong sewage treatment persistence.

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.
