Detailed ways

After the applicant's research and analysis, the reason for this problem (most of them are columnar during the feeding process, so when they contact, the contact area is too small, which slows down the reaction efficiency of the agent and sewage) is the existing domestic water discharge. There are still some problems in the device. In order to ensure that the discharged sewage can meet the established standards, the sewage needs to be treated before discharge to remove excessive trace elements in the sewage. Therefore, it is necessary to add chemicals to the water, while the existing Most of the chemical addition work is to add the powdered chemical directly into the treatment tank, and then let the chemical process itself with the wastewater in the treatment tank. Wrapping or agglomeration of the medicine due to the storage method will increase the difficulty of the solution of the medicine. In order to avoid the above problems, some companies will grind the medicine before adding the medicine, thereby reducing the dosage of the medicine. Then it is prepared into a prefabricated agent, and then the prefabricated agent is put into the treatment tank to complete the treatment of domestic sewage, but most of them are columnar during the putting process, so when they are in contact, the contact area is too large small, thus slowing down the reaction efficiency of the medicament and the sewage. In order to increase the contact area between the medicament and the sewage, the present invention is provided with a discharge part, and when it is necessary to add the medicament solution to the treatment tank, at this time Through the operation of the opening and closing motor, the opening and closing plate can be moved, and then it can be separated from the limit ball, and then the solution in the dosing tank moves along the inclined direction of the guide plate, and then the water flowing out of the connecting pipe will meet the limit ball. Collisions between the surfaces of the bit spheres will cause the flowing water column to form multiple small water droplets, which will then be sprayed, and then the small water droplets will enter the treatment tank and merge with the sewage in the treatment tank, so that the medicine can be mixed with the trace amount of water in the sewage The elements react to complete the purification of sewage, and then the treatment tank completes the discharge of sewage through the valve set at the bottom.
