Problems solved by technology
[0002] Food waste wastewater is the sewage formed after processing food waste. Food waste water contains a large amount of organic matter and oil. The existing food waste water treatment system needs to be equipped with multiple centrifugal dehydrators, and the investment in equipment is large, and the treatment The effect is not very good, it cannot effectively reduce the concentration of pollutants such as chemical oxygen demand (COD), total nitrogen (TN), suspended solids (SS), and it is easy to cause secondary pollution

The invention discloses a kitchen wastewater treatment method, which comprises the following steps: S1, adding kitchen wastewater into a sludge concentration tank, and mixing the kitchen wastewater with activated sludge in the sludge concentration tank to form first mixed sludge; S2, adding a flocculating agent into the sludge concentration tank, and mixing the flocculating agent with the first mixed sludge to form second mixed sludge; S3, conveying the second mixed sludge to a centrifugal dehydrator, and carrying out centrifugal dehydration to form a first mixed waste liquid; S4, conveying the first mixed waste liquid into an oil separation tank for treatment; and S5, carrying out oil separation treatment on the first mixed waste liquid, then carrying out air floatation treatment, and conveying the first mixed waste liquid subjected to air floatation treatment to a grid tank. According to the kitchen wastewater treatment method disclosed by the invention, in the sludge concentration tank, the mixed liquid is flocculated and precipitated by adding a flocculating agent, and the chemical oxygen demand, total nitrogen and suspended matters are reduced by utilizing the sludge activityand the flocculating agent, so that the pollutant concentration can be reduced, a centrifugal dehydrator is shared, the investment is reduced, and the cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of kitchen waste treatment, in particular, the invention relates to a kitchen waste water treatment method. Background technique [0002] Food waste wastewater is the sewage formed after processing food waste. Food waste water contains a large amount of organic matter and oil. The existing food waste water treatment system needs to be equipped with multiple centrifugal dehydrators, and the investment in equipment is large, and the treatment The effect is not very good, and it cannot effectively reduce the concentration of pollutants such as chemical oxygen demand (COD), total nitrogen (TN), and suspended solids (SS), which may easily lead to secondary pollution. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention provides a kind of kitchen wastewater treatment method, purpose is to r...
