Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in Figures 1, 2, 3, 4, and 5, a plastic four-compartment septic tank includes a cylinder body 1, a left sealing plate 2, a right sealing plate 3, a fixed rib 4, a first partition plate 5, a first The second partition 6, the third partition 7, the water inlet 8, the cleaning opening 9, the inspection opening 10, the exhaust opening 11, the water outlet 12, the first partition 5, the second partition 6 and the third partition The plate 7 divides the cylinder body 1 into a first grid septic tank 13, a second grid septic tank 14, a third grid septic tank 15, and a fourth grid septic tank 16. The first partition 5, The second partition 6 , the third partition 7 , the left sealing plate 2 , and the right sealing plate 3 are connected to the cylinder body 1 through the fixed ribs 1 , and the upper part of the first septic tank 13 is provided with a water inlet 8 , an exhaust gas Port 11, the top of the first grid septic tank 13 and the third grid septic tank 15 are provided with a clearing port 9, and the top of the second grid septic tank 14 and the fourth grid septic tank 16 are provided with inspection ports 9, the right sealing plate 3 is provided with a water outlet 12, the sewage enters the first grid septic tank 13 through the water inlet 8, and flows through the first grid septic tank 13, the second grid septic tank 13 in turn. The grid septic tank 14 , the third grid septic tank 15 and the fourth grid septic tank 16 are discharged from the water outlet 12 .

The left sealing plate 2 , the first partition 5 , the second partition 6 , the third partition 7 , and the right sealing plate 3 are sequentially distributed on the inner side of the cylinder 1 along the axis, and are heated with the cylinder 1 through the fixing ribs 4 respectively. For fusion connection, a ring of hot fuse 41 is provided on the outer surface of the fixing rib 4 , and the fixing rib 4 is thermally fused to the cylinder body 1 through the hot fuse 41 . Double function, strong water resistance, improved sealing performance, at the same time fixed ribs play a supporting role, improve structural strength, and solve the problem that the quality of plastic septic tanks with complex structures is not good enough, and the splicing parts are easy to leak. .

The fixed rib 4 is made of PE material, has a ring structure, and the cross section is in the shape of a "concave" shape. The width of the fixed rib 4 is plate thickness+4cm, and the thickness is 2cm.

A first through hole 51 is formed in the upper part of the first partition plate 5 , a second through hole 61 is formed in the upper part of the second partition plate 6 , and a third through hole is formed in the lower part of the third partition plate 7 71. The through-holes are designed with staggered heights to avoid linear short flow, so that the sewage flows in a certain direction of water flow, so the suspended solids in it can be fully precipitated and the effect of sewage treatment is increased.

The first septic tank 13 has a larger capacity, and the second septic tank 14 , the third septic tank 15 and the fourth septic tank 16 have a smaller capacity.

The septic tank barrel 1 is a horizontal cylindrical septic tank, and the entire septic tank adopts HDPE, which fully utilizes the advantages of light material quality, high toughness, acid and alkali corrosion resistance, and long service life, avoiding the need for a barrel. The body cracks and breaks after long-term use.

The septic tank works like this:

The sewage enters into the first grid septic tank 13 through the septic tank water inlet 8, and part of the suspended solids settles to the bottom of the first grid septic tank 13 to realize anaerobic fermentation.

The sewage in the septic tank 13 of the first grid flows into the septic tank 14 of the second grid through the first through hole 51 at the lower part of the first partition plate 5 , and part of the suspended matter is further deposited into the septic tank of the second grid 14 . bottom for anaerobic fermentation.

The sewage in the second compartment septic tank 14 flows into the third compartment septic tank 15 through the second through hole 61 in the upper part of the second partition 6 , and part of the suspended matter is further precipitated into the third compartment septic tank 15 . bottom for anaerobic fermentation.

The sewage in the septic tank 15 of the third grid flows into the septic tank 16 of the fourth grid through the third through holes 71 at the lower part of the third partition 7 , and part of the suspended matter is further deposited into the septic tank of the fourth grid 16 . bottom for anaerobic fermentation.

The sewage in the fourth grid septic tank 16 that has been precipitated four times before and after flows out of the fourth grid septic tank 16 through the septic tank water outlet 12 at the top.

After four precipitations before and after, the content of suspended solids in the sewage flowing out from the top of the fourth septic tank 16 is greatly reduced, thereby achieving preliminary purification. After a certain period of anaerobic fermentation, the organic matter in the suspended solids deposited at the bottom of the first grid septic tank 13, the second grid septic tank 14, the third grid septic tank 15, and the fourth grid septic tank 16 is decomposed. into stable inorganic substances, so that the perishable raw sludge can be converted into stable cooked sludge.
