Problems solved by technology

It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that cannot be purified to a certain standard after primary pollution. Part of the wastewater It also contains acids such as sulfuric acid, hydrochloric acid, and nitric acid, alkalis such as sodium hydroxide, sodium carbonate, and ammonia, and organic waste liquids such as peroxide oxidants such as hydrogen peroxide and reducing agents such as sulfide and hydrazine. This kind of wastewater usually needs to add chemical substances to react before it can be discharged, and after directly adding substances, it needs to be mixed to accelerate its reaction. However, the stirring function of the existing devices is usually one-way rotary stirring, so As a result, the reaction efficiency of wastewater is low, which prolongs the treatment time of wastewater and affects the treatment time of other wastewater

Embodiment 1

[0027] Example 1: Please refer to Figure 1-4, an acid wastewater treatment device, comprising a treatment box 1, a water inlet pipe 2 and an outlet pipe 3 are arranged on the side surface of the treatment box body 1, and the water inlet pipe 2 and the water outlet pipe 3 are respectively located on the side surface of the treatment box body 1 and oppositely arranged, and Both the water inlet pipe 2 and the water outlet pipe 3 are connected to the inside of the treatment box 1, and the treatment box 1 is provided with a driving device 4, the driving device 4 includes a main rotating shaft 41, and the upper and lower ends of the main rotating shaft 41 are fixedly installed with threaded columns 42, A stirring and separating device 5 is arranged on the side surface of the main rotating shaft 41, and the number of the stirring and separating devices 5 is two. The stirring and separating device 5 includes a stirring plate 51, and the two stirring plates 51 are arranged symmetricall...

Embodiment 2

[0028] Embodiment 2: On the basis of Embodiment 1, the user can set the container for reactant injection above the processing box body 1 when using it, and simultaneously open an opening on the processing box body 1 and use an elastic plate to block it, so that When the upper movable block 52 rotates, it can drive the elastic plate to open and close intermittently, so as to achieve intermittent timing and quantitative feeding of reactants, and ensure the efficiency and purification rate of wastewater mixed reaction treatment.

[0029] When in use, because the position setting of the water inlet pipe 2 will allow the waste water to provide the initial power to make the stirring plate 51 rotate when it enters the treatment box 1, the setting of the main shaft 41 and the threaded column 42 will allow the main shaft 41 to rotate when it rotates. reciprocating movement up and down, while the stirring plate 51 can rotate in the forward and reverse directions through the main shaft 41...

Abstract

The invention relates to the technical field of wastewater treatment, and discloses an acid wastewater treatment device, which comprises a treatment box body, wherein a water inlet pipe and a water outlet pipe are arranged on the side surface of the treatment box body, the water inlet pipe and the water outlet pipe are oppositely arranged on the side surface of the treatment box body, the water inlet pipe and the water outlet pipe are both communicated with the interior of the treatment box body, a driving device is arranged in the treatment box body and comprises a main rotating shaft, threaded columns are fixedly mounted at the upper end and the lower end of the main rotating shaft correspondingly, two stirring and separating devices are arranged on the side surface of the main rotating shaft, each stirring and separating device comprises a stirring plate, the two stirring plates are symmetrically located on the side surface of the main rotating shaft correspondingly, and an auxiliary device is arranged in each stirring plate in the same manner. According to the acid wastewater treatment device, the driving device, the stirring and separating device and the auxiliary device are used in cooperation, so that the stirring efficiency and the mixing effect are improved, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an acid wastewater treatment device. Background technique [0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater that flows into drainage pipes and canals. It generally refers to water that cannot be recycled after certain technical treatment or that cannot be purified to a certain standard after primary pollution. Part of the wastewater It also contains acids such as sulfuric acid, hydrochloric acid, and nitric acid, alkalis such as sodium hydroxide, sodium carbonate, and ammonia, and organic waste liquids such as peroxide oxidants such as hydrogen peroxide and reducing agents such as sulfide and hydrazine. This kind of wastewater usually needs to add chemical substances to react before it can be disch...
