Restaurant wastewater oil remover

Abstract

The invention relates to a restaurant wastewater processing device, in particular to a restaurant wastewater processing device integrating dosing mixing, electrical flocculation precipitation and air-flotation separation, which is applicable for removing the oil content in restaurant wastewater. The restaurant wastewater processing device comprises a reactor 1, a medicine storage box 2, a direct current power supply 3, a bracket 4 and a tubular mixer 5. The wastewater is fully mixed with an added flocculating agent in the mixer 5 and then enters a reacting region 18 of the reactor 1. Under the action of an externally-applied electric field, a large amount of microbubbles are generated through electrolyzing the wastewater after flocculation, and the bubbles are upwards floated to the surface of the wastewater after adsorbing the oil and the suspended solid in the wastewater to perform the action of air floatation. The invention has the characteristics of small occupied area, simple structure, high system integration density, convinient operational management, good oil removing effect, large processing amount, stable outlet water quality, low operating cost and the like.

Description

A catering wastewater degreaser technical field The invention relates to a wastewater treatment device, in particular to a catering wastewater treatment device, in particular to a catering wastewater degreaser. Background technique With the rapid development of urban catering service industry, the pollution of oily sewage produced by this industry to the environment is also becoming more and more serious. Catering wastewater contains a large amount of animal and vegetable oils and suspended solids. These substances are discharged directly without treatment, which not only increases the load of urban sewage treatment plants, affects the capacity of urban drainage pipe networks, but also deteriorates water quality. Therefore, the research on the degreasing device for catering wastewater has certain environmental benefits for reducing water pollution and protecting the environment. At present, there are many research reports on degreasers for catering wastewater, mainly foc...

Problems solved by technology

For example, the utility model patent with the publication number CN02261286.6—a new type of catering wastewater processor, uses the principles of dosing and mixing, inclined tube precipitation, and air flotation to continuously analyze oil and solid particles in sewage. The device has a simple structure and is easy to operate, but Large floor area, low operating cost and the need to add chemicals, which makes the cost of wastewater treatment too high; the invention patent of publication number CN200310100829.0-wastewater purification device adopts electric floating device and co-pipe device, and is equipped with a chemical dosing box , oil skimming device, clear water tank and sludge tank are an integrated device for electrochemically purifying catering water, but the device has disadvantages such as complex structure, high manufacturing cost, and large energy consumption.

Judging from the current situation of catering wastewater treatment, a variety of technologies can be applied to the treatment of catering wastewater, but from a practical point of view, so far, there is no mature practical technology for catering wastewater treatment, which generally occupies a large area and the treatment effect is unstable. and other shortcomings
