Water distributor of trickling biofilm reactor

Abstract

The invention relates to a water distributor of a trickling biofilm reactor. The water distributor comprises an upper water inlet plate and a lower trickling plate, wherein the upper water inlet plateand the lower trickling plate are fixedly connected, and a clearance space is left between the upper water inlet plate and the lower trickling plate, and the periphery of the clearance space is sealed to form a water distribution interlayer, and space height of the water distribution interlayer is 0.2- 0.8 mm; water distribution interlayer water inlet holes are formed in the upper water inlet plate, a plurality of trickling water outlet holes of the water distribution interlayer are formed in the lower trickling plate, and the total cross-sectional area of the plurality of trickling water outlet holes is larger than the cross-sectional area of the water distribution interlayer water inlet holes. The water distributor is simple in structure, convenient to use and low in operation and maintenance cost, and can realize 100% trickling water distribution on the basis of liquid surface tension principle, and the water distribution requirement of efficient sewage treatment of a trickling device is met.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a water distributor for a trickling filter biofilm reactor. Background technique [0002] The water distributor is usually used to arrange the amount of water on the working surface of the trickling filter biofilm reactor according to a certain rule for sewage treatment. The most common is to distribute water evenly on the working surface of the trickling filter biofilm reactor. The drip filter water distributors currently used are divided into flat water distributors, ring water distributors, point distributors and tube water distributors. These types of water distributors have more or less deficiencies during use, such as the small water distribution range of point distribution water distributors, and it is easy to reverse short flow and leakage; Water dispensers and annular pipe network water distributors are commonly used tubular water distributors, but these two types of wat...

Problems solved by technology

These types of water distributors have more or less deficiencies during use, such as the small water distribution range of point distribution water distributors, and it is easy to reverse short flow and leakage; Water dispensers and annular pipe network water distributors are commonly used tubular water distributors, but these two types of water distributors have complex structures, difficult maintenance, uneven water distribution, and high requirements for water quality pre-treatment, especially these types The water distribution rate of the water distributor is low. When the concentration of the wastewater to be treated increases, the water distribution effect becomes worse, and the sewage usually flows out at a large flow rate unevenly to distribute the water to the trickling filter biofilm reactor, which has a negative effect on the biological The impact force of the membrane is large, the biofilm is destroyed, and the bacteria flow out with the drainage, which cannot effectively meet the requirements of the trickling filter cloth water in the sewage treatment process of the trickling filter biofilm reactor
