Embodiment 1

[0024] Anti-clogging cyclone screen solid-liquid separator for sewage treatment, see Figures 1 to 3 , including a screen solid-liquid separator 1, a clear water tank 2, a solid waste sedimentation tank 3, a bottom pipeline 4, and an organic fertilizer fermentation tank 5.

[0025] The bottom of the screen solid-liquid separator 1 is conical, and the upper part is provided with a group of screens 12 and a water inlet pipe 11. The screen 12 is an arc-shaped screen, and the water inlet pipe 11 is parallel to the tangent of the arc-shaped screen. Set, and located inside the curved screen. A screen cleaning nozzle 13 is provided near the inner side wall of the screen 12 , and the screen solid-liquid separator 1 communicates with the clean water tank 2 through the screen 12 . The screen 12 is a 60-100 mesh screen.

[0026] The solid waste sedimentation tank 3 is provided with a columnar screen dirt collector 31, and the columnar screen dirt collector 31 divides the solid waste se...

Embodiment 2

[0034] Embodiment 2 is used for the solid-liquid separation system of livestock and poultry breeding wastewater

[0035] Livestock and poultry breeding wastewater enters the screen solid-liquid separator 1 through the water inlet pipe 11 to form a swirl 15, and the clean water flows out through the screen 12, enters the clean water tank 2, and flows out from the water outlet 21 of the clean water tank 2, with a mesh size of 60- 100; the solid waste 14 sinks with the swirling flow and is deposited at the bottom of the vertebral body. The bottom of the vertebral body is connected to the external solid waste settling tank 3 by the bottom pipeline 4. The solid waste settling tank 3 is equipped with a columnar screen dirt collector 31, and the water purification area 32 of the solid waste settling tank 3 is provided with a low-lift water pump 34. The lift water pump 34 is connected with the screen cleaning nozzle 13 . When pumping water, the bottom of the cone of the screen solid-...

Embodiment 3

[0037] Embodiment 3 is used for the solid-liquid separation system of aquaculture industrialization wastewater

[0038] The solid waste in the wastewater discharged from the aquaculture factory is mainly composed of residual bait and fish feces. The content of solid waste is relatively low, but the particles are finer and need to be filtered with a finer screen.

[0039]The waste water discharged from the factory breeding workshop enters the screen solid-liquid separator 1 through the water inlet pipe 11 to form a swirl 15, and the clean water flows out through the screen 12, enters the clean water tank 2, and flows out from the water outlet 21 of the clean water tank 2. The mesh of the screen is 80-120 mesh; the solid waste 14 sinks with the swirling flow and is deposited at the bottom of the vertebral body. The bottom of the vertebral body is connected to the external solid waste settling tank 3 by the bottom pipeline 4. The solid waste settling tank 3 is equipped with a col...

Abstract

The invention provides an anti-clogging vortex screen solid-liquid separator for sewage treatment. The solid-liquid separator comprises a screen solid-liquid separator, a rinsing area, a solid waste sedimentation tank and a bottom pipeline, wherein the screen solid-liquid separator is communicated with the rinsing area through a screen; a columnar screen catch basin is arranged in the solid wastesedimentation tank; one end of the bottom pipeline is communicated with the taper bottom of the screen solid-liquid separator; the other end of the bottom pipeline is communicated with the bottom of an internal sludge area of the solid waste sedimentation tank. The invention further provides an anti-clogging vortex screen solid-liquid separation method for sewage treatment. The solid-liquid separator can not only effectively separate solid waste, but also continuously clean the screen and prevent clogging of the screen, effectively improves the filtering efficiency of the screen, provides an efficient and stable solid-liquid separation scheme for sewage treatment, is simple and feasible, and wide in application range, and has a good application prospect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an anti-clogging cyclone screen solid-liquid separator and a separation method for sewage treatment. Background technique [0002] At present, in sewage treatment technology, solid-liquid separation is one of the most important technologies, which is related to the effectiveness of the subsequent process of sewage treatment. The common methods of solid-liquid separation are sedimentation tanks, such as auxiliary flow sedimentation tanks and flow sand sedimentation tanks. These methods require a large area of ​​equipment and a large investment, and are generally used for primary treatment of large-scale industrial heavy pollution. For small-scale or moderately polluted water treatment, the investment is large and unaffordable. [0003] The solid-liquid separation of livestock and poultry breeding sewage adopts the method of ditch sedimentation, which occupies a large area, takes a...
