Water treatment separation device

Abstract

The invention discloses a water treatment separation device, and belongs to the technical field of water treatment. The device comprises a first tank body, a second tank body and a third tank body, wherein the side wall of the third tank body is respectively connected with an aeration treatment tank and a filter pressing tank; the top wall of the first tank body is connected with a first motor; the output end of the first motor penetrates through the first tank body and is connected with a first stirring rod; the bottom wall of the third tank body is connected with a second motor, the output end of the second motor is connected with a lead screw; the end, away from the second motor, of the lead screw penetrates through the third tank body and is connected with the bottom of the first stirring rod; and the outer wall of the lead screw is sequentially connected with a first baffle, a second baffle and a third baffle. According to the sewage treatment device, it can be effectively guaranteed that precipitation is not affected when sewage and a coagulant are mixed, the continuity of sewage treatment is guaranteed, the water treatment separation efficiency is improved, the sewage treatment quality is further improved through the arrangement of the aeration treatment tank and the filter pressing tank, and meanwhile generated flocculate can be conveniently treated.

Description

Technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment separation device. Background technique [0002] Water is an indispensable natural resource for human development. With the acceleration of urbanization and industrialization, the discharge of domestic sewage and industrial wastewater is increasing, resulting in the continuous deterioration of water quality in natural water bodies. Therefore, it is necessary to effectively treat polluted water. Avoid deteriorating natural water bodies. [0003] The water treatment methods in the prior art mainly include physical treatment and chemical treatment. When using chemical methods to separate dirt and impurities, it is necessary to add a flocculant to the sewage to make the sewage and the flocculant coagulate to produce flocs. After the sewage is precipitated, the flocs produced are precipitated, and then filtered and disinfected to obtain clean water. However, the wa...

[0003] The water treatment methods in the prior art mainly include physical treatment and chemical treatment. When using chemical methods to separate dirt and impurities, it is necessary to add a flocculant to the sewage first, so that the sewage and the flocculant are coagulated to produce flocs, and then the mixed The final sewage is precipitated to precipitate the flocs produced, and then filtered and sterilized to obtain clean water. However, the water treatment and separation device in the prior art is mixed with the sewage and the coagulant and the mixture is precipitated at the same time, which will affect The effect of the mixture sedimentation, and then make the water treatment insufficient, and the mixing of sewage and coagulant and the mixture precipitation step by step will make the water treatment efficiency low, so the water treatment separation device in the prior art needs to be improved
