Description

Integrated treatment device for chemical wastewater Technical Field The invention belongs to the technical field related to chemical wastewater treatment, and particularly relates to an integrated treatment device for chemical wastewater. Background In the chemical production process, a large amount of acidic or alkaline wastewater is generated, and in order to meet the discharge standard or the subsequent treatment requirement, a chemical agent is generally added into the wastewater in a wastewater treatment tank to perform neutralization treatment. The existing chemical wastewater neutralization device mostly adopts a mode of arranging a stirrer or a pesticide spraying device in a treatment tank to enable chemical agents to react with wastewater in a mixing way, so that the pH value of the wastewater is adjusted. The prior art has the following defects for chemical wastewater treatment: In the prior art, chemical wastewater neutralization treatment generally enables chemical agents to be mixed with wastewater through a single stirring device or a simple spraying structure in a treatment tank. Because the wastewater is in an up-down distribution state in the tank body, particularly when the tank body is deeper or the mobility is poorer, the medicament is difficult to uniformly diffuse in areas with different heights, and local neutralization or local unreacted areas are easy to form, so that the neutralization reaction is uneven, and the treatment effect is unstable. In the prior art, in the chemical neutralization process, partial chemical agents are difficult to dissolve completely, and metal ions or impurities in the wastewater are easy to form precipitates or flocculent particles after the reaction. The particles are easy to deposit and adhere to the bottom of the treatment tank or structures such as a pipeline, a filter screen and the like, and can cause flow channel blockage, stirring efficiency reduction and equipment maintenance frequency increase after long-term operation, thereby influencing continuous and stable operation of the wastewater treatment system. In the prior art, the neutralization device is mostly dependent on natural diffusion or local stirring to realize wastewater circulation, and an effective up-down convection flow field is difficult to form. When the concentration of the wastewater is high or the volume of the tank body is large, the overall fluidity of the wastewater is poor, and the neutralized wastewater and the unneutralized wastewater are difficult to exchange in time, so that the reaction time is prolonged, the treatment efficiency is low, and the operation cost is increased. Therefore, it is desirable to provide an integrated treatment device for chemical wastewater to solve the problems of insufficient wastewater mixing, easy particle deposition and blockage, and insufficient circulation flow capacity in the prior art. Disclosure of Invention The invention provides an integrated treatment device for chemical wastewater, which is used for solving the problems of insufficient mixing of upper and lower regions of the wastewater, easy deposition and blockage of particles and insufficient circulation flow capacity in the prior art. The invention discloses an integrated treatment device for chemical wastewater, which is characterized by comprising the following specific technical means: An integrated processing apparatus for chemical wastewater, includes the treatment jar, the inside of treatment jar is fixed to be equipped with the inner tube, still includes: The movable piece is arranged in the treatment tank and can move along the axial direction so as to divide the interior of the treatment tank into at least two neutralization areas with variable volumes; The driving shaft penetrates through the movable piece and is connected with the movable piece in a linkage way, and the driving shaft is matched with a guide driving assembly arranged in the treatment tank so as to generate axial lifting movement and drive the movable piece to synchronously lift when rotating; The injection pipe assembly is arranged on the movable piece and communicated with the neutralization area, one end of the injection pipe assembly can be alternately communicated with waste water in different height areas in the lifting process of the movable piece, and the other end of the injection pipe assembly is used for injecting the waste water into another height area; The stirring assembly is arranged on the outer side of the injection pipe assembly, and the injection pipe assembly can generate autorotation in the lifting process of the movable piece so as to form rotary diffusion flow when the wastewater is injected. Through the structure, the driving shaft rotates and axially lifts under the action of the guiding driving assembly, so that the movable piece is driven to reciprocate in the treatment tank and change the volume of the neutralization area, the jet pipe assembly synchronously lifts along wi
