Description

Urban Water Coastal Ecological Restoration Device

                      

The invention belongs to the technical field of water ecological engineering, and in particular relates to an ecological restoration device for urban water shores.

Background technique

At present, the degradation of water body ecosystem has become a global problem, especially in urban water bodies. On the one hand, a large amount of urban sewage is continuously discharged into water bodies, which makes the ecological environment of urban water bodies continue to deteriorate. The vegetation zone is encroached, and the hard flood control embankment is directly in contact with the water body, which cuts off the connection between the water ecosystem and the terrestrial ecosystem, and destroys various ecological processes of the water body. In addition, the vigorous development of the aquaculture industry and other industries has led to urban water bodies becoming rich. The degree of trophication is increasing, blue-green algae blooms occur frequently, and the water ecological environment is seriously degraded. In order to solve this problem, in recent years, the technical measures adopted at home and abroad mainly contain three types of methods, namely: (1) chemical methods: adding chemical agents to kill algae and decontamination, adding lime powder to denitrify, adding iron salts to promote the precipitation of phosphorus, etc. This method is not only costly, but also easily causes secondary pollution; (2) physical methods: dredging bottom mud, mechanical algae removal, water diversion to wash away silt, etc. Although this method does not have secondary pollution, it cannot fundamentally solve the problem; (3) water body shoreside ecological method: this method is a new technology that has been highly praised at home and abroad in recent years. Theories and methods to repair and restore damaged water bodies, the main technical measures are as follows: ① Plant aquatic plants through geotechnical materials, steel wire mesh and gravel composite planting bases, and cement ecological planting bases to carry out ecological restoration and restoration of the water body shore , this method has a good effect on the stability of the shore structure, and the shore landscape has also been improved to a certain extent, but the effect on the pollutants flowing into the river from the intercepting surface is very limited. ②Plant emergent plants directly on the shore of the water body, and repair and restore the water body through the emergent plant system. Although this method can achieve certain results, the emergent plants are easy to spread, encroach on the river, and affect the normal flood discharge of the water body and river. and shipping features.

Contents of the invention

The purpose of the present invention is achieved in this way: in the coastal zone of urban water bodies, there is provided with: a wetland ecological decontamination and water purification system composed of emergent plant areas, floating and sinking water plant areas, concrete partitions and slag biological permeable walls, The water, air and wind exchange system composed of biofilm water wheels, sail water pumps, water storage tanks and artificial waterfalls, the land-water biological habitat system composed of bio-reef mountains, footbridges, and natural bionic capillary irrigators. An ecological revetment system composed of concrete overflow embankment, vetiver area and shrub area on the shore slope.

In the above system, the concrete overflow embankment is arranged at an angle of 8 to 25° with the flow direction of the water flow, the head of the embankment is connected with the concrete partition, and the tail of the embankment is connected with the slag bio-permeable wall; The area formed by the concrete partition is then divided into the emergent water plant area and the floating and sinking water plant area by the concrete partition. The bio-reef mountain is set up in the zone, and the bio-reef mountain is connected to the shore through a footbridge. Not only flowers and trees are planted on the bio-reef mountain, but also sail water pumps, water storage tanks and artificial waterfalls are installed. For irrigation, the sail water pump is connected to the water storage tank through pipelines, and the artificial waterfall is connected to the water storage tank through pipelines. The biofilm waterwheel waterwheel is set outside the head of the concrete overflow embankment, and its water storage tank is connected with the water storage tank on the bio-reef hill through the water delivery tank; the vetiver area and shrub area on the bank slope are set on the bank slope, and the upper part is The shrub area, the lower part is the vetiver area, and the shrubs and vetiver planted in this area are naturally irrigated by natural bionic capillary irrigators.

The above-mentioned systems form an ecological unit. On both banks of the water body, according to the length of the water body and shore, multiple ecological units can be arranged symmetrically, or multiple ecological units can be arranged in a staggered manner. Multiple ecological units form the ecological environment of the shore. system.

Compared with the chemical method, physical method and water body shore ecological method generally adopted at home and abroad, this invention has the following beneficial effects:

(1) The invention provides growth bases for various plants and habitats for microorganisms, terrestrial animals, benthic organisms, and fish by building biological reef mountains, thereby restoring the diversity of organisms and plants in the urban coastal zone and restoring river courses Ecosystem, improve the self-purification capacity of the river.

(2) The invention can not only restore the ecology of the urban water body and obtain ecological purification, but also prevent wind and waves from scouring the shore, so that the landscape of the urban water body can be significantly improved.

(3) While making full use of solar energy, water energy, wind energy and biological plant energy, the invention can effectively connect and exchange energy in ecological systems such as water, air, wind, biology, plants and humanities.

(4) The invention can effectively control the spread of aquatic plants in river channels, and ensure the safety of navigation and flood discharge.

(5) The invention uses the natural bionic capillary irrigator to irrigate the plants on the shore slope and the biological reef mountain, which can not only effectively save energy, but also provide natural water supply according to the physiological needs of the plants.

(6) The invention not only has a good ecological purification effect, but also has a good embankment sedimentation effect.
