Abstract

The invention discloses a production wastewater treatment process for an automobile park. The production wastewater treatment process comprises the following steps: S1, carrying out pretreatment on sewage, wherein a coarse screen, a water inlet pump station, a fine screen and an aeration precipitation tank are adopted in the pretreatment procedure; and S2, injecting a pretreated wastewater sourceinto a hydrolysis acidification pool for treatment. The invention relates to the technical field of wastewater treatment processes. According to the production wastewater treatment process for the automobile park, deep multi-section sewage interception can be achieved and high sewage dissolving capacity and good filtering effect are obtained through the effects of filtration, adsorption and biodegradation; due to a unique gas and water distribution system and higher backwashing strength, a filter material can be washed more thoroughly; and constant-water-level constant-water-quantity backwashing can avoid the loss of the filter material, and realizes conservation of water and electricity and low energy consumption. Data show that a combination of ozone electromagnetic advanced catalytic oxidation and carbon sand filter tank produces good treatment effect, meets design requirements, and has good environmental benefits and economic benefits; and the production wastewater treatment process can provide reference for high-standard emission and upgrading and reconstruction in other sewage plants.

Description

technical field [0001] The invention relates to the technical field of waste water treatment process, in particular to a process for treating production waste water used in automobile parks. Background technique [0002] An automobile production base covers a total area of ​​about 9.5km2, with an annual output of 600,000 vehicles in the first phase. The sewage treatment of the base mainly collects production wastewater and domestic sewage in the park. The total project size is 15x103m 3 / d, the construction scale of the first phase of the project is 7.5x103m 3 / d, the project covers an area of ​​about 2.0ha, with a total investment of about 120 million yuan, and the discharge water shall be discharged into the landscape canal in the park according to the Tianjin local standard DB12 / 599-2015. [0003] In the existing technology, automobile production wastewater has complex components, poor biodegradability, and contains organic matter such as oil. Conventional sewage treatme...
