The invention relates to a wave eliminating bank protection module and a bank protection structure for a water purification type river channel. The bank protection module comprises a net cage which is woven through metal wires and is located on the outer layer, and a gravel structure arranged in the net cage in a filling manner. The bank protection module further comprises a purifying layer arranged on the surface layer of one side in the net cage in a filling manner. The bank protection structure comprises at least two rows of bank protection modules arranged in a near river bank in a delta shape. A static water area is formed between the bank protection modules and the river bank, and aquatic plants are planted in the static water area. According to the bank protection structure for the water purification type river channel, a novel water flow boundary is built, and the functions of controlling and guiding water flow and protecting the bank are achieved; and in addition, stone such as zeolite, ceramsite and vermiculite with high specific surface area is adopted, the functions of stabilizing gravel and absorbing water force can be achieved, the functions of purifying a water body and improving water quality can be achieved by absorbing pollutants such as heavy metal ions, N and P in water.

The invention discloses a multifunctional environment-friendly dam. The multifunctional environment-friendly dam comprises a long-strip-shaped dam body composed of a plurality of dam units. Each dam unit comprises a first base, a second base and two water insulation rolled plates, wherein the two water insulation rolled plates are arranged on the same sides of the first base and the second base correspondingly; and grids are arranged on the inner sides of the two water insulation rolled plates correspondingly. A caisson is arranged in a work space. A blocky body, a water purification tank and an ultraviolet irradiation light box are arranged in the caisson. The blocky body made from a hydrophobic adsorbing material, the water purification tank for water purification and the ultraviolet irradiation light box for sterilization are mounted in the caisson to be used for fully purifying river pollution. Fish holes are formed in the bottoms of the bases, the up-down positions of the grids can be adjusted, the height is adjusted according to the seasonal water flow changes and fish breeding seasonal changes, and the river ecology damage is reduced as much as possible while the normal functions of the dam units are ensured.

The invention relates to a wave-eliminating bank protecting method of a water purification type riverway. The bank protecting method includes the following steps that the specification of bank protecting modules is determined, the bank protecting modules are prepared and installed, and bank protection ecology is built. Due to the fact that the wave-eliminating bank protecting modules are arranged nearby a water bank of the riverway and are used for retarding a water flow and decreasing the speed of the water flow, a new water flow boundary condition is created, and therefore the effects of controlling and guiding the water flow and protecting the bank are achieved. Meanwhile, a static water micro environment is formed between the wave-eliminating modules and the bank, aquatic plants can be planted, aquatic animals can inhabit in the static water micro environment, and therefore an aquatic animal and plant ecological system is formed, and pollution of bank slope point and face pollution sources on the water quality is relieved. According to the bank protecting method, high-specific-area stones such as zeolite, ceramsite and vermiculite are adopted, stability and water absorption capacity of gravel are achieved, and the effects of purifying water and improving the water quality are achieved by absorbing pollutant substances, such as heavy metal ions, N and P, in water.

The present invention relates to a combination air purifier and wind generator. The combination air purifier and wind generator comprises a wind-receiving unit installed on a central shaft for driving an electric generator mounted in a box-type housing, and an air purifier. The wind-receiving unit includes a governor fixed to an upper end of the central shaft, a spherical blower installed in the middle of the central shaft, and a planar magnetic rotary plate installed at a lower end of the central shaft for receiving both artificial and natural winds. Lower magnets are attached to the top of the box-type housing while upper magnets having the same polarity as the lower magnets are attached to the bottom of the magnetic rotary plate to face the lower magnets. The air purifier includes two air inlets; one air outlet; a copper net, a silver net and a hard charcoal / zeolite net disposed within the air purifier for purifying air introduced thereinto; and a blower interposed between the silver net and the hard charcoal / zeolite net.

The invention relates to an ecological remediation method for a slope of a broken mountain. Ecological remediation can be conducted on a steep cliff wall slope of which the slope surface is smooth andlevel by constructing a slope remediation structure composed of a large-pore vegetation concrete layer, a substrate material layer and a small-pore vegetation concrete layer. The surface roughness ofthe slope sprayed with the large-pore vegetation concrete layer is significantly increased, a substrate material which is subsequently sprayed can not be prone to sliding down, small-pore vegetationconcrete is sprayed to the outer layer of the substrate material, therefore, through the double-layer vegetation concrete structure, it can be better guaranteed that the substrate material is attachedto the slope, and sliding and rain water scouring are avoided. In addition, the large-pore structure of the large-pore vegetation concrete layer is more beneficial for growth of a plant root system,the small-pore vegetation concrete layer can purify non-point source pollution, rotten ecological desilting sludge is added into the substrate material, and the vegetation degradation problem caused by insufficient fertility is solved.
