Problems solved by technology

[0003] The chemical method is one of the methods commonly used by chemical companies to treat wastewater. By adding buffer solution to the wastewater to neutralize the polluting elements in the chemical wastewater, it is transformed into non-pollutant Neutral inorganic salts with any toxic effects; high treatment efficiency; however, due to the relatively simple structure of the tanks used in daily chemical treatment of chemical wastewater, the wastewater cannot be fully mixed with the buffer solution after entering the treatment tank, resulting in A small amount of untreated polluting elements are discharged through the discharge port of the treatment pool, resulting in pollution, which is not conducive to the green production of the chemical industry

Embodiment 1

[0012] Example 1: Such as figure 1 Shown is a chemical wastewater multi-stage treatment pool, the treatment pool is a rectangular pool body 1, a sealing cover 2 is provided above the pool body 1, and a plurality of inclined slopes are provided at the bottom of the pool body 1. Plate structure 6, the sloping plate structure 6 is provided with a filter screen 8 connected to the sealing cover 2, the bottom of the pool body 1 and the side of the sloping plate structure 6 are provided with a plurality of rotating agitators 7.

Embodiment 2

[0013] Example 2: Such as figure 1 As shown, the top of the pool body 1 is provided with a waste water inlet 3, the tail end of the pool body 1 is provided with a drain port 5, the bottom of the pool body 1 is provided with a buffer solution input port 4, and the end of the drain port A pH detection device 9 is provided to detect the pH value of the wastewater discharged from the discharge port 5 through the pH detection device 9, so as to control the flow of the buffer solution and the wastewater to achieve a sufficient treatment effect.

Embodiment 3

[0014] Example 3: Such as figure 1 As shown, the inclination angle between the sloping plate structure 6 and the bottom of the pool body 1 is 60-75°, and the sloping plate structure at this inclination angle facilitates the circulation of wastewater between multiple sloping plate structures, while ensuring that the sloping plate structure Individual processing effects between plate structures.

Abstract

The invention discloses a multi-stage chemical wastewater treatment tank. The treatment tank is a rectangular tank body, wherein a sealing cover is arranged above the tank body; a plurality of inclined plate structures are arranged at the bottom of the tank body; filter screens on the inclined plate structures are connected with the sealing cover; a plurality of rotary stirrers are arranged at the bottom of the tank body and at the side of the inclined plate structures. The multi-stage chemical wastewater treatment tank is simple in structure and convenient to operate; the wastewater and buffer solution are sufficiently mixed by the plurality of the rotary stirrers, the inclined plate structures and the filter screen structures which are additionally arranged in the tank body; meanwhile, the multi-stage chemical wastewater treatment tank has a good treatment effect by multi-layer treatment and staged purification, and especially has an outstanding effect for treating acid or alkaline wastewater.

Description

technical field [0001] The invention relates to the field of chemical wastewater treatment, in particular to a multi-stage chemical wastewater treatment pool. Background technique [0002] Industrial wastewater refers to the wastewater, sewage and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants produced in the production process. Industrial wastewater treatment methods can be divided into four categories according to their working principles, namely physical treatment, chemical treatment, physical chemical treatment and biological treatment. [0003] The chemical method is one of the methods commonly used by chemical companies to treat wastewater. By adding buffer solution to the wastewater to neutralize the polluting elements in the chemical wastewater, it is converted into neutral inorganic salts without any toxic effects of pollutants;...
