Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technical field, concretely is based on MBBR filler siphon drainage type constructed wetland system sewage treatment device. BACKGROUND

[0002] Sewage usually refers to the waste water from life and production. Sewage mainly has domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. At present, various kinds of sewage are treated, and various kinds of treatment equipment are also used. Membrane bioreactor technology is a new type of high-efficiency sewage treatment process combining biological treatment process with membrane separation technology, and has very broad application prospect. MBBR is the abbreviation of moving bed biofilm reactor. The process improves the biomass and biological species in the reactor by adding a certain amount of suspended carrier to the reactor. The main features are that the carrier filler with special structure is used, and the treatment capacity and treatment effect can be improved by adding the carrier filler; it has strong impact resistance and stable performance; the pool body is not blocked, and the pool volume is fully utilized; the system is flexible and convenient; and it has long service life.

[0003] However, the existing sewage treatment is gradually completed through sludge sedimentation tank, MBBR reaction tank and clean water tank. When the water after the reaction with the filler enters the inside of the clean water tank, due to the existence of a certain amount of filler, not only the water will enter the inside of the clean water tank, but also the filler will be pumped into the inside of the clean water tank under the driving of the water pump. At this time, the filler mixed in the water will flow into the clean water tank with the water flow. With the continuous increase of the amount of the filler entering the clean water tank, the heavy filler will fall to the bottom of the clean water tank under the action of its gravity, and the light filler will float on the water surface in the clean water tank. The existence of the filler will reduce the effect of sewage purification and affect the water quality after sewage purification. UTILITY MODEL CONTENTS
