Treatment device for precipitating solid fine particles in wastewater

Abstract

The invention discloses a treatment device for precipitating solid fine particles in wastewater. The treatment device comprises a main water inlet pipe (1), an acid-alkali pond (2), a hazardous chemical pond (3), at least one collection pond (4), a blending pond (5), a coagulation pond (6), a sedimentation pond (7) and a dosing device, wherein the acid-alkali pond (2), the hazardous chemical pond (3) and the collection pond (4) are respectively communicated with the blending pond (5) through diversion outlet pipes (9), the blending pond (5) is communicated with the coagulation pond (6) through a water outlet pipe (12), and the coagulation pond (6) is communicated with the sedimentation pond (7) through a water pipe (11). The treatment device adopting the structure, disclosed by the invention, can temporarily store wastewater in different natures to prevent the wastewater from being mixed indiscriminately, thereby ensuring that each type of the wastewater can keep the nature before treatment, being favorable for follow-up treatment, simultaneously enabling the precipitation of suspended matters and colloids in the wastewater to be more sufficient and improving the wastewater treatment quality.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a treatment device for precipitating fine solids in waste water. Background technique [0002] In industrial production or life, a lot of waste water will inevitably be produced, and there are usually some harmful substances in the waste water. If it is discharged directly without treatment, it will have an adverse impact on the surrounding environment. Therefore, from the perspective of protecting the environment, wastewater must be treated before being discharged. Wastewater treatment mainly uses physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve the purpose of recycling and reusing wastewater and making full use of water resources. In wastewater treatment, physical treatment is usually used for pretreatment. Taking high-concentration organic wastewater as an example, micro-electrolysis technology in physical tre...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a processing device for precipitating fine-grained solids in wastewater, which solves the problem that in the past, when wastewater was pretreated, a larger pool was often used as a pretreatment pool, and various wastewaters were not classified and temporarily stored, resulting in a gap between wastewater. Reactions will affect the subsequent processing links. At the same time, simple natural precipitation cannot remove all suspended solids and colloids.
