Description
Technical Field
The utility model belongs to environmental engineering and water treatment engineering field, concretely relates to three-phase separator.
Background
Currently, anaerobic reactors for sewage treatment are mainly classified into two types: one type is a low-load anaerobic filter tank and an anaerobic baffle plate reactor, and the anaerobic reactor has a simple structure and does not contain a three-phase separator inside; the other type is an anaerobic reactor comprising a three-phase separator, which has high sewage treatment efficiency and is widely applied to sewage treatment.
The working principle of the anaerobic reactor comprising the three-phase separator is as follows: the sewage is lifted to the bottom of the anaerobic reactor by a water pump, the sewage is uniformly distributed on the whole cross section by using a water distribution system at the bottom, and simultaneously, the sewage is fully contacted and mass-transferred with high-concentration anaerobic sludge by using the outlet pressure of inlet water and the gas generation effect, so that organic matters in the sewage are degraded to generate methane, and the methane drives the sewage to slowly rise in a reaction region and contact with the anaerobic sludge so as to further degrade the organic matters. During the process that the biogas, the water and the sludge simultaneously rise, the biogas firstly enters the three-phase separator and is discharged through a pipeline, the sludge and the wastewater rise to the separation area through the gap of the three-phase separator, the sludge is precipitated and concentrated in the separation area and flows back to the lower part of the three-phase separator to keep the biomass in the anaerobic reactor, and the precipitated effluent is discharged out of the tank through the pipeline.
The design and the operation effect of the three-phase separator determine whether the anaerobic reactor can maintain high sludge concentration and treatment load.
In the anaerobic methanogenesis reactor, although most of gas can automatically escape from the mud-water mixed liquor for separation, part of gas is attached to the periphery of sludge flocs or sludge particles in the form of fine bubbles and even enters the inside of the sludge flocs, and enters a three-phase separator together with sludge and wastewater. The specific gravity of the sludge flocs is reduced after the bubbles are carried by the sludge flocs, and the sludge flocs can flow out of the three-phase separator along with water, so that the separation effect is poor. When a large amount of sludge is lost, the concentration of the sludge in the reactor is greatly reduced, and the treatment effect of the reactor on the wastewater is influenced.
