Embodiment Construction

[0020] Such as figure 1 , figure 2 , image 3 As shown, the pulse aeration biological contact oxidation water treatment device is composed of a pulse generator 1, an aeration system 2, a biological filler area 3, an air valve 13, and a pool 4. The pulse generator 1 is fixed at the bottom of the pool 4, the biological filler area 3 is fixed at the upper part of the pool 4, the aeration system 2 is located between the pulse generator 1 and the biological filler area 3, and the aeration system 2 and the pulse generator 1 pass through a valve 13 connections are interlinked.

[0021] The pulse generator 1 is composed of a straight tube 5 , a water seal cover 6 , a water seal bucket 7 , a collection cover 8 , an inner connecting plate 9 and an outer connecting plate 10 . Straight barrel 5, water seal cover 6, water seal bucket 7 and collecting cover 8 planes are circular or polygonal. The upper end of the water-sealed bucket 7 is open, and the lower end is closed and fixed with...

Abstract

The invention provides a pulse aeration biological contact oxidation water treatment device, belonging to the technical field of water treatment engineering. The device consists of a water pool, an aeration system, a biological padding area, a pulse generator, an air valve and the like. The pulse generator, the aeration system and the biological padding area are successively installed from the bottom of the pool to the upper part; the aeration system and the pulse generator are connected and communicated through the air valve; an air supplying tube continuously supplies air for the pulse generator; after the pulse generator is full of air, the air is quickly released to the aeration system through the air valve, and is released to the biological padding area in a form of small bubbles through the aeration system; and after the air is completely released, the inlet of the aeration system is closed by the air valve so as to stop water from entering. When the device provided by the invention operates, the outside can supply the air for the device in a continuous and low-strength form, and the aeration of the inner padding area is in an intermittent pulse and high strength form; and when micro-polluted water with large oxygen demand is treated, the pulse aeration achieves the aeration strength required when an aged biological film falls off on the premise of guaranteeing the oxygen demand, thereby reducing the air supplying amount and saving energy.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a water quality treatment device combining a pulse aeration device and a biological contact oxidation device. Background technique [0002] The continuous aeration biological contact oxidation water treatment technology is a water treatment technology that effectively removes ammonia nitrogen and organic matter in water. It is widely used in sewage treatment, pretreatment of slightly polluted drinking water sources, and improvement of water environment and water quality. The continuous aeration biological contact oxidation water treatment device is composed of an aeration system installed at the bottom of the pool and a biological filler suspended in the water. The compressed air supplied by the blower is continuously released into the water in the form of small bubbles through the aeration system, and Rising through the biofill zone, it eventually enters the atmosphere. Under the con...
