Problems solved by technology

With the continuous development of society, the amount of architectural coatings is also increasing. However, the composition of wastewater produced in the production of architectural coatings is complex. If the wastewater is directly entered into the existing architectural coating wastewater treatment system (flocculation, filtration, etc.) for treatment , the treatment cost is high, and the treated wastewater is not easy to meet the standard
At the same time, in the production of architectural coatings, nano-scale ultrafine inorganic powders such as titanium dioxide and heavy calcium are usually used in large quantities, resulting in a large amount of solid waste in the production wastewater. Thick agglomeration can easily block the pipeline, which will cause equipment damage and greatly affect the efficiency of sewage treatment

Abstract

The invention discloses a pretreatment device for wastewater from building coating production. The device comprises a membrane filtration box, a transition box, a filter box and a filter mechanism, wherein the transition box is arranged at the upper end of the membrane filtration box; the filter box is arranged at the upper end of the transition box; a membrane filter is arranged in the membrane filtration box; the lower end of the membrane filter is connected with a filter pipe which is communicated with a liquid storage chamber arranged in the membrane filtration box; a detection mechanism is arranged on the left side of the liquid storage chamber; a circulating pump is arranged on the right side of the liquid storage chamber; the filter mechanism is arranged in the filter box; sliding chutes are formed on the two sides in the filter box; sliders matched with the sliding chutes for use are arranged on the two sides of the filter mechanism; filter chambers are arranged in the filter mechanism in a bilateral symmetry manner. Most solid waste in the wastewater from building coating production can be removed by automatic circulating filtration, so that risk of blockage of a wastewater treatment equipment pipeline is reduced, meanwhile, the filter chambers are arranged in the filter mechanism in a bilateral symmetry manner, the solid waste is discharged immediately, the operationis simple, the filter effect is guaranteed, and the filter efficiency is improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment equipment, in particular to a wastewater pretreatment device for architectural paint production. Background technique [0002] Architectural coatings are coatings that are applied to buildings, to decorate buildings, or to protect buildings. With the continuous development of society, the amount of architectural coatings is also increasing. However, the composition of wastewater produced in the production of architectural coatings is complex. If the wastewater is directly entered into the existing architectural coating wastewater treatment system (flocculation, filtration, etc.) for treatment , its treatment cost is high, and the treated wastewater is not easy to meet the standard. At the same time, in the production of architectural coatings, nano-scale ultrafine inorganic powders such as titanium dioxide and heavy calcium are usually used in large quantities, resulting in a large amount of s...
