Problems solved by technology

Organic silicon wastewater has high COD concentration, high salt content, poor biochemical properties, large fluctuations, and unstable water quality. It is an extremely difficult biochemical industrial wastewater
However, when the traditional A / O process encounters influent water quality or water volume fluctuations, it will cause difficulty in the selection and adaptation of bacteria, resulting in the inability of the biochemical system to continuously and stably reach the standard, and the treatment efficiency will drop or directly cause the system to collapse.

Embodiment 1

[0062] The flow chart of the process method of organic silicon wastewater treatment of the present embodiment is as figure 1 As shown, the organic silicon wastewater is pretreated before entering the ABR anaerobic baffle reactor 1, and the organic silicon wastewater passes through the oil separation sedimentation tank, the homogenization tank, the air flotation tank and the neutralization flocculation sedimentation tank in sequence. The oil separation sedimentation tank removes light oil and heavy oil pollutants and solid impurities in organic silicon wastewater. The homogenization tank balances the changes in the water quality, water volume and water temperature of the wastewater, and reduces the impact of the inconsistency of the wastewater on the subsequent ABR anaerobic baffle reactor 1. The air flotation tank absorbs and removes fine particle pollutants in the wastewater. The neutralization flocculation sedimentation tank further removes extremely fine particle pollutant...

Abstract

The invention provides a process for treating organic silicon wastewater, the method comprising the following steps: the organic silicon wastewater passes through the multi-stage reaction chamber of the ABR anaerobic baffle reactor, and is mixed with the granular activated carbon in the reaction chamber Perform hydrolysis and acidification reaction with anaerobic microorganisms to obtain intermediate wastewater, while the sludge discharge pipeline and gas distribution pipeline of the water distribution and gas distribution system cooperate with the sludge discharge and exhaust of the ABR anaerobic baffle reactor; the intermediate wastewater Enter the PACT aerobic pool, and flow in the biochemical treatment area, side reaction area, sedimentation area, and aggregation reflux area of ​​the PACT aerobic pool, and perform deep degradation with powdered activated carbon and aerobic microorganisms to obtain produced water, while the The sedimentation zone and the accumulation reflux zone recycle the powdered activated carbon and aerobic microorganisms to the biochemical treatment zone for reuse.

Description

technical field [0001] The invention belongs to the technical field of industrial sewage treatment, and in particular relates to a process method for organic silicon wastewater treatment. Background technique [0002] With the development of social economy, the demand for high-performance silicone materials is increasing. Silicone materials have been widely used in construction, petrochemical, medical, daily chemical, new energy, aerospace and other fields. The production of organosilicon materials will generate a large amount of wastewater, which has the characteristics of high COD concentration, strong acidity, high salinity, poor biodegradability, and difficult treatment. Wastewater contains a variety of inorganic and organic substances, the composition is complex and changeable, the pH value of wastewater is low, and the floating oil is serious. Depending on the production process of organic silicon materials, the nature of organic silicon wastewater will also change. ...
