Embodiment Construction

[0033] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0034] like figure 1 and figure 2 As shown, an anaerobic tank 7, an equipment area and a reaction box 27 are arranged side by side on the square base 1 of the kitchen wastewater treatment device. The reaction box 27 is divided into a pretreatment area and a main treatment area by a partition. On one side of the pretreatment area, the first PH adjustment tank 2 and the flocculation tank 3 are arranged side by side from left to right. The floating pool 5 and the second PH adjustment pool 6 are provided with an air flotation reaction pool 4 in the middle of the pretreatment area; a primary aerobic pool 9 and a primary anoxic pool 8 are arranged side by side from left to right in the main treatment area, The other side is provided with a secondary aerobic tank 11, the secondary anoxic tank 10 is arranged on the left side of the secondary ae...

Abstract

The invention discloses a kitchen wastewater treatment device which comprises a pretreatment zone, an anaerobic tank, a dosing device and a main treatment zone, wherein a first pH value adjusting tank, a flocculation basin, an air floating water outlet tank and a second pH value adjusting tank of the pretreatment zone are distributed close to the outer side of an air floating reaction tank; and aprimary anoxic pond, a primary aerobiotic pond, a secondary anoxic pond and a secondary aerobiotic pond of the main treatment zone are sequentially arranged. The invention further discloses a kitchenwastewater treatment method. The kitchen wastewater treatment device can be easily arranged in a same reaction tank, is compact in structure, reasonable in arrangement, easy in wastewater treatment device integration, small in floor space and possible in overall movement, transfer and hoisting and is low in civil engineering cost and convenient and rapid to mount because of a pry block mounting mode.

Description

technical field [0001] The invention relates to the technical field of kitchen wastewater treatment, in particular to a kitchen wastewater treatment device and a treatment method. Background technique [0002] Food waste includes corrosive food waste produced by households, canteens, restaurants, etc. Food waste mainly comes from the water contained in the food waste itself, the water generated during the fermentation process of the waste, and the water produced by various processes during the treatment of food waste. of moisture. Kitchen wastewater is a typical high-concentration organic wastewater with irregular discharge and many impurities and suspended solids. It is more difficult to treat than domestic garbage wastewater. The color of kitchen wastewater is black, the composition is complex, the concentration of organic matter and ammonia nitrogen is high, and it mainly contains pollutants such as food fiber, starch, fat, animal and vegetable oil, various condiments, d...
