Embodiment Construction

[0015] The use of the present invention makes the filler flow orderly in water, which is an important factor for the success of the MBBR process. The traditional paddle-type underwater propulsion and agitator are difficult to complete. It is not easy to meet the technical requirements of evenly distributing the filler in the pool when it is transported at the water end. The invention proposes the principle of negative pressure lifting, pressurized water blowing and conveying: the filler is sucked into the vacuum tank by using the negative pressure principle, and then the water and filler are blown out of the vacuum tank together by compressed air or pressurized into the tank and transported to a distant place through the pipeline.

[0016] During the specific implementation of the present invention, the collection cover is connected with the vacuum tank through the pipeline, the vacuum degree of the vacuum tank is generally 60-80Kpa, the vacuum tank is connected with the air co...

Abstract

The invention relates to an MBBR (Moving Bed Biofilm Reactor) packing material negative pressure and positive pressure combined conveying method which is characterized by comprising the following steps of: collecting an MBBR packing material via an inlet water collecting pipeline in a vacuum type and connecting to a vacuum tank, connecting the top of the vacuum tank with a negative pressure generating apparatus via a pipeline, cutting off the vacuum after the MBBR packing material is collected to the vacuum tank, and opening a positive pressure pipeline communicated with the vacuum tank. A positive air pressure pipeline is also arranged at the top of the vacuum tank, the MBBR packing material is ejected to a water pool from a packing material ejection pipeline, and a water outlet pipe connected with the vacuum tank is communicated to the water inelt end of the MBBR water pool. With the method, the packing material is not easy to break, microorganisms on the surface of the packing material are not easy to flush away, and thus, the aerobic biochemical efficiency of a carrier is greatly improved. The purpose of conveying the MBBR packing material to a long distance can be achieved.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to realizing a paddleless MBBR filler conveying device, so as to keep the filler in an efficient working state and greatly reduce the loss of the filler. Background technique [0002] In the process of biochemical water treatment, the MBBR (Moving Bed Biofilm Reactor) moving bed biofilm reactor has a good process effect and the quality of the treated water is the best. Suspended fillers in MBBR can grow various types of organisms. The principle of MBBR process is to increase the biomass and biological species in the reactor by adding a certain amount of suspended carriers to the reactor, thereby improving the treatment efficiency of the reactor. Since the packing density is close to that of water, it is completely mixed with water during aeration, and the environment for microbial growth is gas, liquid and solid. The collision and shearing action of the carrier in the water ma...
