The invention relates to agentia feeding equipment, in particular to sewage treatment solid agentia feeding equipment and aims to achieve the technical effects that by means of the sewage treatment solid agentia feeding equipment, feeding efficiency can be improved, and labor intensity can be lowered. According to the technical scheme, the sewage treatment solid agentia feeding equipment comprisesa cart, an Arbic-number-seven-shaped frame, a feeding hopper, a barrel body, a first bearing block, a first rotating shaft, a slotted disc, a first belt wheel, a fixing plate, a motor, a second beltwheel, a flat belt and the like. The right side of the cart is connected with the Arbic-number-seven-shaped frame, the left side face of the Arbic-number-seven-shaped frame is connected with the feeding hopper, the bottom of the feeding hopper is connected with the barrel body, and the bottom of the barrel body is provided with a discharging opening. The solid sewage treatment agentia can be conveyed into a shell body intermittently when the slotted disc is rotated clockwise, the solid sewage treatment agentia can be fed into sewage when a spiral blade is rotated clockwise, therefore the feeding efficiency can be improved, and the labor intensity can be lowered.
