Problems solved by technology

[0004] However, river pollution has the characteristics of many pollution channels, serious pollution, many types of pollutants, large quantity, wide pollution area, wide distribution, serious damage to natural ecosystems, and non-point source pollution is becoming more and more serious.
A single river management method can no longer effectively guarantee the complete restoration of the river water environment

Embodiment 1

[0034] like Figures 1 to 8 As shown, a water body ecological purification system based on nano-coupling materials of the present invention includes: an exogenous interception unit 1, an endogenous control unit 2 for reducing and controlling endogenous pollution (not shown in the figure, mainly operated manually). ), artificial purification unit 3 and ecological restoration unit 4 for restoration of river ecological functions:

[0035] The external source interception unit 1 includes an ecological interception ditch 11 and a slope protection ecological interception zone 12 respectively located on both sides of the river channel; the ecological interception ditches 11 are excavated and arranged on the side of the river bank with a smaller slope, and the slope protection ecological interception zone 12 is arranged on the larger river bank slope. side;

[0036]The ecological interception ditch 11 includes a number of repeating units, and the repeating unit includes an intercepti...

Embodiment 2

[0045] Different from embodiment 1, the membrane frame is fixed on the welded steel frame and placed in the river. In embodiment 2, the membrane frame is fixed on the liftable steel frame 325 which can be lifted and lowered by the support rod, and then placed in the river, and the hollow fiber A dissolved oxygen sensor 326 is provided on one side of the membrane module to detect the dissolved oxygen around the hollow fiber membrane module; the four support rods of the elevating steel frame 325 are electric telescopic rods, and the height is adjusted through the intelligent control terminal, and the electric telescopic rods pass through the The motor (waterproof motor) drives the telescopic rod for telescopic movement;

[0046] The intelligent control terminal includes an industrial IoT gateway 327, a cloud platform 328 and a user terminal 329. The cloud platform 328 is signally connected to the liftable steel frame 325 (wherein, the signal connection of the liftable steel frame...

Embodiment 3

[0048] Example 3: Ecological Treatment Project of Xishigang River Channel, Chang'an Town, Haining

[0049] The Xishigang river channel is 360m long, 9-10 meters wide, 360m long, 1.1m-1.6m deep, and has not been dredged. Instantaneous, total nitrogen situation is serious. There is a farm and a fruit forest on both sides of the river. Among them, the farm has a large amount of sewage, and there is no isolation. The non-point source pollution of the river is uncontrollable on rainy days. There is no aquatic plant distribution in the whole river, and the water turbidity is high.

[0050] In view of the situation of the river in the project, we use a water ecological purification system based on nano-coupled materials for governance.

[0051] 1. Use retaining dams and mud pumps to dredging the entire river section, and send the cleaned sludge to the garbage incineration plant; throw in the bottom sludge remover for more detailed treatment of the residual sludge.

[0052] 2. Sele...

Abstract

The invention discloses an ecological water body purification system based on a nano-coupling material. The ecological water body purification system comprises an exogenous interception unit, an endogenous control unit, an artificial purification unit and an ecological restoration unit, wherein the exogenous intercepting unit comprises an ecological intercepting ditch and a slope protection ecological intercepting belt which are respectively positioned on two sides of a river channel; the ecological intercepting ditch comprises a plurality of intercepting ditches and intercepting pools communicating with the intercepting ditches, gravel and a water treatment slow-release agent are laid on the bottom walls of the intercepting ditches, and porous ceramic particles are laid on the bottom walls of the intercepting pools; the slope protection ecological interception belt comprises a plurality of moisture absorption ecological bags stacked layer by layer along a slope surface, and moisture absorption materials are contained in the moisture absorption ecological bags; the artificial purification unit comprises an air supply device and an aeration device; the air supply device comprises afan and a pipeline; and the aeration device comprises a membrane frame and a hollow fiber membrane assembly fixed on the membrane frame, the membrane frame is of a hollow structure, one end of the membrane frame is connected with a pipeline, and the membrane frame is used for conveying gas to the hollow fiber membrane assembly. According to the system, a complete ecological chain is constructed, river water self-purification capacity is enhanced, and water purification effect is stabilized.

Description

technical field [0001] The invention relates to a water body ecological purification system based on nano-coupling materials, and belongs to the technical field of environmental protection. Background technique [0002] With the rapid development of economy and society and the continuous expansion of cities, in the process of urban construction, the pollution of urban water environment in my country has become increasingly serious. The water bodies in urban rivers are mostly polluted by organic pollutants, nitrogen, phosphorus and other pollutants. It is a common phenomenon in all urban rivers in my country, and the governance of urban black and odorous rivers will be the key environmental problem to be solved in the future. [0003] At present, many technologies for river purification have been developed. According to different principles of pollution control, river pollution control technologies can be divided into four categories: physical method, chemical method, microbia...
