The guide frame and the liquid storage frame are connected by a conduit, and an exhaust port is opened on the surface of the purification box. Disinfectant is stored in the liquid storage frame. When the wind shield rotates, it contacts and drives the guide plate to rotate, and the resistance encountered by the wind shield when rotating is increased by contact with the guide plate, thereby achieving control of the flow of harmful gases and avoiding excessive flow of harmful gases, which leads to insufficient contact between the harmful gases and the disinfectant.

A filter plate is fixedly installed inside the liquid storage frame, and the filter plate can effectively prevent the disinfectant from splashing out of the liquid storage frame, thereby increasing the subsequent maintenance cost.

The sliding of the sliding rod can further turn over the materials accumulated at the bottom of the reaction bin, thereby improving the effect of sewage treatment.

[0010] The lifting plate moves upward and drives the sliding plate to move upward, and the lifting plate moves upward to drive the sliding plate to move upward. The material storage box is slidably mounted on the surface of the purification box, and the limited quantity box is fixedly penetrated through the inner and outer walls below the material storage box, and the sliding plate is slidably mounted on the inside of the limited quantity box.

[0014] The present invention provides a multifunctional composite sewage treatment and purification device, which has the following beneficial effects:

[0015] (1) In the composite sewage treatment and purification device, the gas inside the reaction chamber contacts the wind shield through the guide frame and drives it to rotate. The rotation of the wind shield controls the flow of harmful gases under the action of the guide frame, thereby avoiding excessive flow of harmful gases, resulting in insufficient contact between the harmful gases and the disinfectant, which in turn affects the health of the staff. At the same time, the filter plate can effectively prevent the disinfectant from splashing out of the liquid storage frame, thereby increasing the subsequent maintenance cost.

[0016] (2) In this composite sewage treatment and purification device, the servo motor is started to drive the spiral stirring rod and the L-shaped turning rod to rotate through the transmission shaft, which can effectively turn over the foreign matter contained in the sewage, avoid the accumulation of foreign matter on the substrate causing insufficient reaction, and improve the sewage treatment effect. At the same time, the L-shaped turning plate drives the sliding rod to move through the receiving rod and the connecting rod, further turning over the materials accumulated at the bottom of the reaction chamber, and improving the sewage treatment effect.

[0017] (3) In the composite sewage treatment and purification device, the L-shaped tipping rod rotates to contact and squeeze the lifting plate and the sliding plate to move upward. The sliding plate moves upward so that the reactant in the storage box enters the interior of the limiting box through the feed port, thereby achieving quantitative multiple discharge of the reactant, increasing the contact area between the reactant and the sewage and thus improving the sewage treatment efficiency. At the same time, by moving the L-shaped limit rod and the storage box, the lifting plate is separated from the movement track of the L-shaped tipping rod, thereby reducing the loss of the equipment, extending the service life of the equipment, and reducing the subsequent maintenance cost.

[0018] (4) In the composite sewage treatment and purification device, when the reaction plate is replaced, the receiving plate is moved and the baffle is moved upward under the action of the fixed block to close the purification box, thereby preventing the gas from being discharged when the reaction plate is replaced and causing pollution to the working environment, thereby affecting the health of the staff. At the same time, the receiving plate moves away from the purification box to release the limit on the sliding block, and the movement of the sliding block will close the purification box, thereby improving the sealing effect of the purification box and preventing the gas that has not been completely purified from being discharged to the outside.

[0033] When the present embodiment is working, when sewage is treated, harmful gases inside the reaction chamber 2 enter the interior of the purification box 31 through the air inlet and the conduit on the surface of the guide frame 32.
