Siphon type full automatic aeration biologicall filtering chamber

Abstract

The siphoning automatic aerating biofilter includes filter basin with filtering material, inlet channel, water outlet weir and timing water tank. It has also water outlet pipe connected to the lattices of the filter basin and water outlet tank, draining siphon pipe connected to the water seal well, water inlet siphon pipe connected to the water inlet channel, auxiliary water inlet siphon pipe connected to the water inlet siphon pipe, water inlet exhaust pipe, water inlet siphonage eliminating pipe, auxiliary water drainage siphon pipe connected to the draining siphon pipe, draining exhaust pipe, draining siphonage eliminating pipe, etc. The present invention has the advantages of completely hydraulic controlling, easy running, no need of clear water tank, no need of back flush pump, low cost, etc.

Description

technical field [0001] The invention relates to a siphon type fully automatic aerated biological filter. Background technique [0002] The biological aerated filter is a sewage treatment process that combines the contact oxidation process and the suspended solids filtration process. The process principle is to fill the filter with a certain amount of granular filter material with a small particle size, and a biofilm grows on the surface of the filter material. , the inside of the filter is aerated, and when the sewage flows through, due to the high concentration of biofilm attached to the filter material, its strong oxidative degradation ability is used to quickly degrade the pollutants in the wastewater. The biological flocculation of the membrane intercepts a large amount of suspended solids in the sewage, and ensures that the detached biofilm will not float out with the water, thereby achieving the purpose of purifying the wastewater. As the filtrat...

Problems solved by technology

The main disadvantages of this flushing method are: (1) It is necessary to set up a special backwashing pump. Due to the large amount of backwashing water, the power of the backwashing pump is relatively large, which increases equipment investment, equipment maintenance and operating electricity costs; (2) must Set up a backwashing pool to store backwashing water. Due to the large amount of backwashing water, the volume of the backwashing pool is often large, which increases the cost of civil engineering; Backwash valve and drain valve are used to control the direction of water flow, which increases the cost of the valve on the one hand, and increases the difficulty of operation and management on the other hand
