Problems solved by technology

[0002] All kinds of sewage contain a large amount of larger particles and suspended solids that are difficult to settle, some are difficult to biodegrade, and some are biodegradable but have become macromolecular cluster structures, which will bring a lot to the subsequent biochemical treatment of sewage. Great difficulty, these difficult to remove larger particles and difficult to settle suspended solids in sewage, increase COD (chemical oxygen demand), greatly increase the burden of subsequent treatment, need to prolong the biochemical time, increase the volume of the functional pool

Embodiment 1

[0013] Such as figure 1 , figure 2 As shown, the sewage diversion tank suction filtration system includes a bracket 1, two main rollers 2 arranged at both ends of the bracket 1, a filter cloth belt 3 set on the two main rollers 2, and a filter cloth belt 3 arranged between the two main rollers 2 The sump 31 , the vacuum box 4 arranged on one side of the sump 31 , the water inlet 5 arranged above the sump 31 , and the two main rollers 2 are driven by motors. When in use, the sewage is collected in the sump, the sewage enters the water inlet tank 5 through the water inlet pipe 52, and then enters the overflow tank 51 from the water inlet tank 5, and then the overflow tank 51 overflows on the filter cloth belt 3, and the filter cloth belt 3 The moisture content on the surface is sucked in a large amount in the vacuum box 4 when passing through the vacuum box 4, enters the water collection tank 31 through the water seal pipe, or enters in the water collection tank 41 through the...

Embodiment 2

[0015] Such as figure 1 , figure 2 As shown, a spiral mud outlet 6 is provided under the main roller 2 and the filter cloth belt 3, and a mud scraper 7 is arranged directly above the spiral mud outlet 6, and the mud scraper 7 is used to scrape off the filter cloth. With the sludge on the outside of the belt 3, a screw shaft 61 is arranged in the screw mud discharge tank 6, and the screw shaft 61 is driven by a motor.

Embodiment 3

[0017] Such as figure 1 , figure 2 As shown, the water inlet tank 5 is provided with an overflow tank 51, and the support below the two main rollers 2 is provided with two auxiliary rollers 21 to change the direction of movement of the filter cloth belt 3. The two main rollers 2 are provided with There is a tension adjustment mechanism, the tension adjustment mechanism 22 is composed of a movable seat 222 installed at both ends of the main roller 2 and an adjustment screw 221. The adjustment bolt 221 is installed on the bracket 1, and the inner end of the adjustment bolt 221 is fixed on the movable On the seat 222, the movable seat 222 can be adjusted left and right.

Abstract

The invention relates to environment-friendly equipment and functional equipment for a sewage diversion process, in particular to a sewage diversion trench suction filter system. The sewage diversion trench suction filter system comprises a bracket, two main rollers, filter cloth belts, a water collecting groove, a vacuum box and a water inlet groove, wherein the two main rollers are arranged at two end parts of the bracket; the filter cloth belts are sleeved on the two main rollers; the water collecting groove is arranged between the two main rollers; the vacuum box is arranged on one side of the water collecting groove; the water inlet groove is arranged above the water collecting groove; and the two main rollers are driven by a motor. By adoption of the structure, the sewage diversion trench suction filter system can remove large-particle solid pollutant (comprising suspended matters and floating matters) from sewage and can reduce sludge quantity of the sewage greatly. By the sewage diversion trench suction filter mechanism, large particles and the suspending matters difficult to settle can be removed from the sewage through suction filtering, COD (chemical oxygen demand) can be reduced by over 50-60 percent, the burden of the subsequent treatment is greatly reduced, biochemical time can be shortened, and the volume of a functional pool can be reduced.

Description

technical field [0001] The invention relates to environmental protection equipment, functional equipment used for sewage diversion technology, in particular to a sewage diversion tank suction and filtration system. Background technique [0002] All kinds of sewage contain a large amount of larger particles and suspended solids that are difficult to settle, some are difficult to biodegrade, and some are biodegradable but have become macromolecular cluster structures, which will bring a lot to the subsequent biochemical treatment of sewage. It is very difficult. The large particles and suspended solids that are difficult to remove in the sewage increase the COD (chemical oxygen demand), which greatly increases the burden of subsequent treatment. It is necessary to prolong the biochemical time and increase the volume of the functional pool. Contents of the invention [0003] The purpose of the present invention is to provide a sewage diversion tank suction filtration system, ...
