A common method for treating chemical wastewater is to use a method for purification and filtration, such as adsorption filtration in the physical method, that is, using an adsorbent to adsorb harmful particles in the wastewater, or reacting through chemical agents, chemical agents include pH adjusters, redox agents, disinfectants, etc. However, the existing chemical wastewater treatment devices basically adopt too single a treatment method, and the secondary pollution prevention during the chemical filtration treatment reaction during the treatment process is not perfect.

The filter material 202 in this structure can be selected from activated carbon, sand and gravel or other materials with adsorption effects, and can be replaced through the movable structure between the filling frame 201 and the sedimentation bin 2.

The use method and advantages of the utility model: The sewage treatment device based on chemical agents, when in use, works as follows:

As shown in Figures 1 to 5, first, the chemical wastewater is poured into the sedimentation bin 2 from the water inlet 1.

The check plate 305 at one end of the feeding port 304 can only be opened toward the inner wall of the reaction bin 3. Therefore, the gas and heat generated during the reaction will not be returned from the feed port 304. When some chemical agents react, the reaction temperature can be increased by the heating rod 308 to accelerate the reaction process. The gas generated by the reaction will pass upward through the water-gas separation filter plate 302 to separate the gas and enter the gas recovery port 303 for recovery. The solid particles produced by the reaction can be accumulated through the slag outlet 306 and regularly cleaned through the warehouse door 307. After the reaction inside the reaction warehouse 3 is completed, the centrifugal pump 5 is turned on to pump the reacted liquid into the flocculation tank 7. Flocculant is added to the flocculation tank 7 to crystallize the harmful substances in the water into large particles, which are then filtered through the tail filter plate 701 to finally meet the emission standards and be discharged through the water outlet 703.
