Water distributor for trickling filter biofilm reactor

Abstract

The invention relates to a water distributor of a drip filter biofilm reactor, which comprises an upper water inlet plate and a lower drip drain plate, the upper water inlet plate and the lower drip drain plate are fixedly connected, and the upper water inlet plate and the lower drip drain plate are connected between the upper water inlet plate and the lower drip drain plate There is a gap space, and the periphery of the gap space is sealed to form a water distribution interlayer. The space height of the water distribution interlayer is 0.2-0.8mm. A number of drip outlet holes of the water-distributing interlayer are arranged on the drip-glass plate, and the sum of the cross-sectional areas of the several drip-out holes is larger than the cross-sectional area of ​​the water inlet holes of the water-distributing interlayer. The invention has the advantages of simple structure, convenient use, and low operation and maintenance costs. The water distributor utilizes the principle of liquid surface tension to realize water distribution at a 100% drop rate, and meets the water distribution requirements of a drip filter device for efficiently treating sewage.

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
