Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic structural diagram of the advection grit chamber of the present invention.

The specific implementation mode is as follows:

the utility model will be further described with reference to the accompanying drawings.

As shown in figure 1, the utility model relates to a new energy village and town sewage treatment system which mainly comprises a water collecting tank 1, an adjusting tank 2, an advection grit chamber 3, an anaerobic tank 4, an anoxic tank 5, an aerobic tank 6, a membrane tank 7, a clean water tank 8 and a metering tank 9, wherein sewage flows in sequence. Wherein, dispose thick grid canal 10 in the catch basin 1 for get rid of the thick suspended solid that probably blocks up water pump unit and pipeline valve, 3 front ends of advection grit chamber dispose thin grid canal 11, the rear end disposes membrane grid canal 12, thin grid canal 11 separates at 3 front ends of advection grit chamber to less solid debris, and then after the granule settlement in 3 middle sections of advection grit chamber, separate tiny solid suspended solid through membrane grid canal 12 at last, make sewage get into the biological reaction flow.

During the water pump-out entering advection grit chamber 3 of 2 bottoms in equalizing basin, 2 upper portion overflow liquids in equalizing basin pass through pipe connection to thick grid canal 10, extract the comparatively even sewage entering advection grit chamber 3 in 2 bottoms in equalizing basin, and the sewage of taking the suspended solid to overflow on adjusting basin 2 returns to thick grid canal 10 and separates debris once more, forms virtuous circle.

3 middle sections bottoms of advection grit chamber are equipped with two grit chambers 30, and lie in the middle section and be equipped with first baffle 31, second baffle 32 and third baffle 33 after to in the past in proper order, first baffle 31 and third baffle 33 are located middle section both sides upper portion, and second baffle 32 is located the middle section lower part. That is, sewage is during through 3 middle sections of advection grit chamber, be stopped by first baffle 31, the rivers can turn to down, be favorable to the solid particle to sink into first grit chamber 30 this moment, then rivers upwards and cross second baffle 32 downwards, a large amount of solid particles can be subsided by blockking of second baffle 32 in this in-process, be stopped by third baffle 33, rivers will have a decurrent turn after crossing second baffle 32, make the solid particle subside once more, so wavy rivers moving path, can make the solid particle subside fast, reduce the length of advection grit chamber 3.

Preferably, the first partition plate 31 is correspondingly positioned above the first grit chamber, the second partition plate 32 is correspondingly positioned at the joint between the two grit chambers, and the third partition plate 33 is correspondingly positioned above the second grit chamber, so that solid particles can be purposefully prevented from settling into the corresponding grit chamber.
