Described first step fermenting case, second stage fermenting case and third stage fermenting case top are respectively equipped with venting port, and described first step fermenting case, second stage fermenting case and third stage fermenting case bottom are respectively equipped with waste material clean-up port.Can be utilized collecting methane by venting port, discharge natural pond liquid, by cleaning natural pond, waste material clean-up port slag by discharge port.
This plastic steel biogas septic tank described also comprises feed-pipe, and this feed-pipe comprises vertical pipe and is connected to the S shape elbow of vertical pipe upper end, and the box house of the first fermenting case is stretched in this vertical pipe lower end by opening for feed; The level height of described vertical pipe lower end is lower than the first outlet.Described S shape elbow refers to the S shape elbow of 90-degree rotation.
The invention has the beneficial effects as follows:
1) the present invention is provided with S shape elbow to feed-pipe, after fecal sewage enters septic tank by feed-pipe, the lower concave part branch of S shape elbow remains a certain amount of sewage, and residual sewage can intercept air and enter septic tank by feed-pipe, provides the environment of an anaerobic.
2) feed-pipe vertical pipe lower end of the present invention level height is lower than the first outlet, ensure that in anaerobic fermentation process, feed-pipe vertical pipe lower end is positioned at below fecal sewage liquid level all the time, namely vertical pipe lower end is flooded by fecal sewage all the time, prevent the biogas in septic tank from leaking into from feed-pipe in air, polluted air.
3) the present invention adopts three grade fermemtation case cascade fermentation, the level height of the connecting tube between three grade fermemtation case raises step by step, and the level height of discharge gate is the highest, can guarantee that fermentation whole process is in anaerobic state all the time like this, ensure the effect of anaerobically fermenting, three grade fermemtation can extend the fermentation time of ight soil greatly simultaneously, changes excrement effective, and fluid is clarified.
4) opening for feed level height of the present invention is higher than the level height of discharge port, and the fecal sewage therefore in septic tank can not form refluence phenomenon.
