Embodiment 1

[0035] Such as figure 1 As shown in -3, the catering wastewater treatment device of the present invention is composed of a solid-liquid and oil-water separation section, a three-stage biological contact oxidation section, a vertical flow sedimentation tank mud-water separation section, a biological filter bed filtration section, a phosphorus removal section and an ultraviolet sterilization section. composition. The overall length, width and height of the equipment are 4800mm, 1800mm and 2500mm respectively.

[0036] The solid-liquid and oil-water separation section is composed of five grease traps connected in sequence. The solid-liquid and oil-water separation section is built in an underground construction at 1.5 meters underground, so that the temperature of the water body is controlled at 12-15 degrees. The last five sections use integrated complete sets of equipment or random combination of each section according to needs. Among the 5 grease traps, the 1st chamber of the ...

Abstract

The invention relates to a systematic treatment method and device for restaurant wastewater, and belongs to the technical field of environmental engineering. The method comprises the steps that solid-liquid separation treatment is preliminarily performed on the restaurant wastewater to separate out solid residue precipitates; oil-water separation treatment is performed to lower the oil content of the restaurant wastewater to below 15 mg / L; the restaurant wastewater obtained through oil-water separation treatment is treated through hydrolysis and contact oxidation by adopting a three-level biological contact oxidation method; mud-water separation is performed after contact oxidation treatment is finished; the restaurant wastewater is treated through a bio-filter bed taking quartz sand and pelelith as media; deep phosphorus removal is performed on a water body by taking limestone as a framework and taking an aluminum preparation as packing; ultraviolet sterilization treatment is performed. Accordingly, the advantages of being reliable in technology, little in investment, easy to maintain, convenient to operate and manage, free of secondary pollution and the like are achieved.

Description

technical field [0001] The present invention relates to a treatment method and device for a catering wastewater system, in particular to an integrated water treatment method for disposing of independent or comprehensive catering wastewater so that the effluent reaches the Grade A Standard of GB18918-2002 Pollutant Discharge Standard for Urban Sewage Treatment Plants A device and a device belong to the technical field of environmental engineering. Background technique [0002] In recent years, with the continuous development of the economy and the adjustment of the industrial structure, the service industry has developed rapidly, among which the catering and tourism accommodation industries have also developed rapidly, resulting in a sharp increase in the discharge of catering wastewater, especially in farmhouses, ecological agriculture and tourism. A large number of independent small catering service systems in the form of inns have emerged, and the point pollution caused by...
