Glass fiber reinforced plastic septic tank

Abstract

The invention discloses a glass fiber reinforced plastic septic tank which comprises a shell, wherein reinforcing ribs are welded on the outer wall of the shell; an excrement inlet is formed in one end of the shell, and an excrement outlet is formed in the other end of the shell; a first treatment chamber, a second treatment chamber and a third treatment chamber are arranged in the shell; a first partitioning plate is arranged between the first treatment chamber and the second treatment chamber; the first partitioning plate is welded on the inner wall of the shell; a first excrement passing pipe is arranged on the first partitioning plate; a second partitioning plate is arranged between the second treatment chamber and the third treatment chamber; the second partitioning plate is welded on the inner wall of the shell; a second excrement passing pipe is arranged on the second partitioning plate; a first decontamination port, a second decontamination port and a third decontamination port are arranged on the upper surface of the shell; and the first decontamination port is positioned above the first treatment chamber. By arranging the decontamination ports, sludge can be conveniently cleared; and by arranging a suction fan, internal methane can be sucked out so as to prevent the shell from bursting.

Description

technical field [0001] The invention relates to the technical field of septic tanks, in particular to a glass reinforced plastic septic tank. Background technique [0002] At present, most of the brick and cement mortar septic tanks are used in the market. The construction period of this type of septic tank is long, difficult, high in cost, and the structure is not conducive to maintenance and sediment treatment. Brick septic tanks are prone to leakage , it is difficult to establish inspection ports, and the later maintenance costs are relatively high. In terms of function, due to the poor airtightness of the structure, it is easy to cause incomplete anaerobic reaction in the septic tank, the reaction cycle is long, the content of BOD and COD is large, and the sewage discharge is not up to standard, which makes the post-treatment time-consuming and laborious; in terms of structure, most septic tanks There is no vent hole in the tank, and the long-term closed fermentation of...

Problems solved by technology

[0002] At present, most of the brick and cement mortar septic tanks are used in the market. The construction period of this type of septic tank is long, difficult, high in cost, and the structure is not conducive to maintenance and sediment treatment. Brick septic tanks are prone to leakage , it is difficult to establish an inspection port, and the later maintenance cost is relatively high

In terms of function, due to the poor airtightness of the structure, it is easy to cause incomplete anaerobic reaction in the septic tank, the reaction cycle is long, the content of BOD and COD is large, and the sewage discharge is not up to standard, which makes the post-treatment time-consuming and laborious; in terms of structure, most septic tanks There is no vent hole in the tank, and the long-term closed fermentation of the septic tank will produce a large amount of methane gas. When the methane gas exceeds the standard or encounters an open flame, it is easy to cause a fire in the septic tank, or even an explosion accident, resulting in serious casualties and economic losses.
