Problems solved by technology

[0004] 1. In the middle and rear sections of the plate-type interception net, the stuffing is blocked due to excessive water flow and reduced thrust of the submersible propeller;
[0005] 2. Due to the physical characteristics of the plate-type interception net, its bending and tensile strength is small and it is easy to deform. Therefore, when designing, it is necessary to adopt a smaller flow rate through the hole, so that the area of ​​​​the interception net is large and the equipment cost is high;
[0009] 6. To prevent the blockage of the interception net, a high-power submersible thruster must be used, which consumes a lot of energy and increases operating costs.

Embodiment 1

[0036] The water collecting pipe 6 passes through the pool wall of the water treatment pool and communicates with the outside world. The water treatment pool is provided with a thruster to keep the water in the pool flowing in a directional manner, and the separation device extends along the direction of the water flow. Wherein, the water treatment pool is at least two adjacent circular pools nested inside and outside, water enters from the innermost pool and is discharged out layer by layer. This fully mixed water treatment tank has a relatively high flow rate, so it has strong impact resistance, relatively uniform distribution of bacteria, uniform distribution of fillers in the entire tank, and almost the same speed of circulation. A water return port is provided between the outer pool 71 and the inner pool 72, and a drain port is provided between the outer pool 71 and the outside world, and the water collecting pipe 6 is connected between the drain port and the water return ...

Embodiment 2

[0040] Such as Figure 5 As shown, in this embodiment, no return water is needed, so the water collecting pipe 6 only needs to be connected to the drain of the pool. The water collecting pipe and the solid-liquid separator are in the middle of the pool. connected to the drain of the pool. The water treatment tank adopting this method is generally a baffle type, and its water flow velocity is relatively slow. In the interception net method of the prior art, in order to prevent the accumulation of fillers, the flow velocity needs to be increased deliberately, and the energy consumption and equipment loss are relatively large. In the present invention, the solid-liquid separator is arranged in the middle of the water treatment tank, where the flow direction of the water flow is basically the same, and the water flow is the most stable. The filler can be carried away by the water flow instead of staying near the separation device, which can also reduce energy consumption and redu...

Abstract

The invention discloses a solid-liquid separator for water treatment. The solid-liquid separator for water treatment comprises a water collecting pipe and at least two separating devices communicated with the water collecting pipe and mounted on the same, and cylinder walls of the separating devices are provided with filtering holes. A water treatment pond using the solid-liquid separator for water treatment is characterized in that the water collecting pipe penetrates through the wall of the water treatment pond to be communicated with the outside, a water pusher arranged in the water treatment pond enables water therein to keep directional flowing, and the separating devices extend along the water flow direction. The water treatment pond is formed by at least two adjacent circular-ring-shaped pond bodies by inner and outer nesting, the water enters from the innermost pond body and is drained outwards layer by layer, the inner pond body is provided with a water outlet for draining the water to the outer pond body, a water draining outlet is formed between the outer pond body and the outside, and the water collecting pipe is connected between a water return port of the inner pond body and the water draining outlet of the outer pond body. The solid-liquid separator for water treatment and the water treatment pond are applicable to water treatment.

Description

technical field [0001] The invention relates to the technical field of water treatment. Background technique [0002] Nowadays, in the MBBR process technology, the plate type interception net is mainly used in conjunction with the submersible flow booster. The water enters the MBBR pool from the water inlet, and there is agitator in the pool. The agitator is installed on the walkway plate, and there is an aeration device at the bottom of the pool, so that the filler and water are fully mixed. The treated water goes out through the plate interception net, and the filler is removed. It is intercepted in the pool, and circulates in the pool through the action of the submersible thruster. [0003] The combination of the plate-type intercepting net and the submersible thruster has the following disadvantages: [0004] 1. In the middle and rear sections of the plate-type interception net, the stuffing is blocked due to excessive water flow and reduced thrust of the submersible p...
