Aluminum alloy disc-shaped trapezoidal magneto thread kitchen sewage treatment equipment

Abstract

The invention relates to domestic sewage treatment equipment and discloses aluminum alloy disc-shaped trapezoidal magneto thread kitchen sewage treatment equipment. The equipment comprises a kitchen washing pool, a three-stage barrier set, oil removal equipment, centrifugal equipment, a salt-tolerant anaerobic biofilm reactor, a salt-tolerant aerobic biofilm reactor and a thread energy recovery reverse osmosis system as improvements: an internal thread on a volute outlet boss is fixedly connected with an external thread on a switching high-pressure tube in a sealed manner so as to form a pressurization screwed joint; a thread energy recovery booster pump is composed of a pressure increase threaded pump part and a threaded pressure switch part; the pressure increase threaded pump part is driven by a disc-shaped trapezoidal magneto; a booster pump suction port and an overall fixed screw hole are respectively formed in the front end face of the threaded booster pump body; a through hole is formed in a pressurization flange plate and corresponds to the overall fixed screw hole; a fastening screw penetrates through the through hole in the pressurization flange plate and is matched with the overall fixed screw hole; and a pressurization center drain hole is aligned at the booster pump suction port. The equipment disclosed by the invention is of a threaded pipeline connecting structure and is simple in structure.

Description

technical field [0001] The invention relates to a domestic sewage treatment device, in particular to an aluminum alloy disc-type trapezoidal magneto threaded kitchen sewage treatment device for harmless discharge and recycling of canteen and hotel kitchen garbage leachate or washing water. 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 salinization. Therefore, the salt co...

AI Technical Summary

Problems solved by technology

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