Method for treating kitchen wastewater by applying aluminum alloy disk type trapezoid magnetor thread machinery

Abstract

The invention relates to a domestic wastewater treatment method, in particular to a method for treating kitchen wastewater by applying aluminum alloy disk type trapezoid magnetor thread machinery. The aluminum alloy disk type trapezoid magnetor thread machinery comprises a kitchen washing basin, three stages of sleeved-assembling barriers, deoiling equipment, centrifugal equipment, a salt-resisting anaerobic biofilm reactor, a salt-resisting aerobic biofilm reactor and a thread energy recycling reverse osmosis system; a thread energy recycling booster pump consists of a boosting thread pump part and a thread pressure exchanger part; the boosting thread pump part is driven by a disk type trapezoid magnetor; as an improvement, the method comprises assembling of the disk type trapezoid magnetor, connection of a screwed joint pipeline and working processes of three operation procedures; internal threads on a boss at an outlet of a volute are hermitically connected and fixed with external threads on a conversion high-pressure pipe to form a boosting screwed joint; a coarse mesh barrier, a moderate mesh barrier and a fine mesh barrier in the three stages of sleeved-assembling barriers are assembled in a sleeved manner; all the stages are fixed by quick screws, and intercepted solids are convenient to remove and clear.

Description

technical field [0001] The invention relates to a method for treating domestic sewage, in particular to a method for treating kitchen sewage by using an aluminum alloy disc-type trapezoidal magneto screw device for harmless discharge and recycling of leachate or washing water from kitchen garbage in canteens and hotels. Background technique [0002] At present, the recycling technology of food waste mainly focuses on fertilizer technology, which is to transform food waste into organic fertilizers rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium. A virtuous circle is an important way to economically and effectively treat and eliminate food waste. However, the high salt content of food waste makes the quality of compost products not high, which not only inhibits the activity of microbial transformation and reduces composting efficiency, but also easily causes soil acidification and damage to crop roots. Long-term use can also lead to soil salini...

AI Technical Summary

Problems solved by technology

Large and medium-sized cities with concentrated populations often have expensive housing prices, and the rent in particularly prosperous areas accounts for the main proportion of the entire operating cost. Therefore, the sewage treatment method that occupies a huge space is difficult to be accepted by canteen and hotel operators, and the water discharge of kitchens cannot be accepted. be effectively controlled
