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 present application relates to sulfur autotrophic equipment technical field, propose a kind of for coal chemical industry salt process sulfur autotrophic equipment, including reactor main body, three partitions and material feeder, the partition is fixedly arranged in the reactor main body, sliding hole is opened in the middle of the partition, water hole is opened in the outer edge position of the partition located in middle;The material feeder includes mesh tube, bottom plate and driving device, the mesh tube is slidably arranged between three sliding holes, and feeding port is opened on the circumferential side of the mesh tube;The bottom plate is fixedly arranged in the mesh tube and below the feeding port;The driving device is used to drive the mesh tube to move in the direction perpendicular to the partition.The present application is by opening sliding hole on partition, and setting mesh tube, bottom plate and driving device, the mesh tube is moved using driving device, sulfur autotrophic carrier can be evenly filled into reactor main body, so as to improve the water purification efficiency of the present sulfur autotrophic equipment.

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.
