This utility model relates to the field of green environmental protection technology, and in particular to an activated carbon dispensing device, including a hopper and a tank. A dispensing pipe is installed at the bottom of the hopper, and a connecting pipe connects the dispensing pipe and the hopper. A fan is installed at one end of the dispensing pipe near the hopper, and the other end of the dispensing pipe is located on the upper side of the tank. The fan blows air towards the end of the dispensing pipe furthest from the hopper. The hopper holds activated carbon, and the connecting pipe connects the hopper to the dispensing pipe. The fan blows the activated carbon from the hopper into the upper side of the tank, realizing the dispensing function of activated carbon from the hopper to the tank. The use of a fan to transport the activated carbon through a rigid pipe reduces the risk of damage to the activated carbon caused by screw rotation, thus minimizing the impact on water purification efficiency.

The invention relates to the technical field of water conservancy projects, and discloses a water conservancy project gate with a water purification mechanism, which comprises door frames, a bottom plate and a gate plate, the side part of the gate plate is provided with an impurity removal assembly, a shell is slidably arranged between the door frames, the inner sides of the door frames are provided with driving assemblies for driving the shell to lift, and the outer side of the shell is connected with a water pipe; a sand flowing opening is formed in the lower side of the flashboard, a baffle is arranged on the side portion of the sand flowing opening in a sliding mode, a pipeline communicated with the sand flowing opening is installed on the outer side of the flashboard, and the water outlet end of the pipeline is connected with a sand bag. The shell drives the water row to descend, water is pumped into the water row through the water pipe, water flow is sprayed through the spray head, deposited silt is raised and mixed into lower-layer river water, the sand flowing opening is opened, the lower-side river water mixed with a large amount of silt flows into the sand bag through the sand flowing opening and the pipeline, and the river water flows out through the sand bag. The silt is collected in the sandbag, so that the water purification effect is improved.

The utility model discloses an unpowered self-purification composite filter material tail water advanced treatment device, and belongs to the technical field of sewage treatment. Comprising a water inlet buffer tank, a drop aeration tank, a constructed wetland and a water outlet well which are sequentially communicated according to a downward stepped structure, a composite filter material reaction tank is further arranged between the drop aeration tank and the constructed wetland, and the composite filter material reaction tank is filled with a composite filter material for adsorbing and degrading pollutants; the drop aeration tank is communicated with the upper part of the composite filter material reaction tank through a water inlet pipeline, and the bottom of the composite filter material reaction tank is communicated with the constructed wetland through a water outlet pipeline. According to the utility model, the composite filter material unit is additionally arranged between the drop aeration unit and the wetland unit in the traditional unpowered treatment device, so that the problem of blockage caused by the fact that the conventional filter material is arranged at the bottom of the constructed wetland is solved, and the whole water purification capacity of the device can be further improved by adjusting the type of the composite filter material and the like.

This utility model relates to the field of water purification technology, and more particularly to a slow filtration water purification device based on a biofilm attached to activated carbon. It includes a first shell and a second shell, connected by a connecting pipe. The first shell contains an activated carbon-coated felt anode layer and an activated carbon-coated felt cathode layer. Both the first and second shells contain a quartz sand-modified activated carbon layer. A ring-shaped water distributor is positioned above the quartz sand-modified activated carbon layer, and a lower pad layer is positioned below it. An ultraviolet lamp is also installed inside the second shell. This utility model, by attaching a biofilm to the surface of activated carbon, utilizes the metabolic and biodegradation capabilities of microorganisms. Simultaneously, it combines the treated water flow with the activated carbon, and through the synergistic effect of the biofilm and adsorption, improves the removal rate of harmful substances in the water, enhances the removal capacity for various pollutants, and improves water purification efficiency and quality.
