Problems solved by technology

There is a competition problem between adsorption and coagulation in the powder feeding of the water absorption well and before the coagulation reaction, resulting in an increase in the dosage of powdered activated carbon
Dosing powder before filtration should be the best position for activated carbon to play a role, but it is inevitable that the turbidity of the effluent will increase due to the penetration of the filter area.

no. 1 example

[0027] For the sake of clarity, the same spatial coordinate system is used in the following figures, so as to facilitate the understanding of the mutual positional relationship among the figures.

[0028] The area referred to in the present invention is essentially a pool capable of performing specific functions, and a plurality of areas with different functions constitute a complete water treatment pool. The activated carbon adsorption zone of this embodiment is referred to figure 1 , the activated carbon adsorption area is surrounded by the surrounding wall and the bottom of the area. The raw water from the upstream enters the rectification area on the left side of the suspension wall 3 from the water inlet pipe 1 as the water inlet. The powder feeding device 4 is arranged in the rectification area. A powder feeding pipe 41 and five powder feeding branch pipes 42 are formed. The center line of the powder feeding pipe 41 is in the Y axis. Seen from the XY plane, the water flo...

no. 2 example

[0032] The difference between this example and the previous example is that the anti-settling device 5 is composed of a tap water source with pressure and a plurality of showers evenly distributed at the bottom of the activated carbon adsorption area. Each shower is connected with the tap water source through a pipeline, and each The showers all spray towards the negative direction of the Z axis.

no. 3 example

[0034] The difference between this example and the first example is that the volume of the activated carbon adsorption area is relatively small, and the size of the rectification area in the X-axis direction is relatively small, so only the powder feeding pipe 41 is provided and the powder feeding branch pipe 42 is cancelled.

Abstract

The invention relates to an active carbon adsorption zone and a water treatment pool, and belongs to the technical field of water purification equipment. A purpose of the present invention is to solvethe problem of low adsorption efficiency of active carbon in water treatment. The active carbon adsorption zone comprises: a water inlet channel positioned on the upstream end of the active carbon adsorption zone, and a water outlet channel positioned on the downstream end; a powder feeding pipe positioned near to the water inlet channel, wherein the center line of the powder feeding pipe is arranged perpendicular to a water flow direction, and a plurality of powder feeding holes are arranged on the pipe wall; a suspension wall positioned on the downstream of the powder feeding pipe, whereinthe suspension wall spans the water flow cross section and is vertically arranged, and a water passing port is formed between the bottom edge of the suspension wall and the bottom of the zone; and ananti-sink device arranged on the bottom portion of the active carbon adsorption zone. According to the present invention, the active carbon adsorption zone is arranged in the water treatment pool; andthe active carbon adsorption zone has advantages of simple structure and good adsorption effect.

Description

technical field [0001] The invention relates to water purification equipment, and in particular relates to an activated carbon adsorption area and a water treatment pool. Background technique [0002] The existing water treatment pool is divided into coagulation reaction area, sedimentation area and filtration area in sequence according to the flow direction of raw water inflow. Each area forms a basically independent pool with four walls and a bottom. The fluid communication between each area is realized through inlet and outlet pipes or holes. . [0003] In recent years, due to the increasingly serious pollution of water sources, the use of powdered activated carbon in water treatment has increased year by year, especially when the quality of water sources is subject to seasonal changes or sudden pollution, adding powdered activated carbon is an effective way to remove organic matter flexibly and easily. measure. [0004] During the use of powdered activated carbon, the ...
