The fish pond 3 is filled with culture water bodies which penetrate through the upper part of the instant sewage disposal pond bottom 200, between the middle upright posts 4 of the preset row direction 6 and between the sewage guide walls 100. The water area for aquaculture in the fish pond 3 is limited in the area of the multi-span greenhouse aquaculture sewage disposal assembly 1, namely, the water area between the instant sewage disposal pond bottom 200 and the sewage guide walls 100 at the two sides of the water area is called a first water area 7, the first water area 7 is arranged to prevent the non-selective sedimentation of the aquaculture excrement in each part of the fish pond 3, the sewage guide walls 100 are arranged to prevent the aquaculture excrement from falling into the bottom of the fish pond 3 between the middle upright posts 4 of the preset row 6, and the multi-span greenhouse aquaculture sewage disposal assembly 1 is arranged to prevent the accumulation, decomposition and deterioration of the aquaculture water at the bottom of the fish pond 3.

The area surrounded by the multi-span greenhouse aquaculture sewage disposal assembly 1 is a first water area 7, and the first water area 7 can be arranged in the whole area of the instant sewage disposal tank bottom 200 in the length direction, or can be only arranged in a partial area of the instant sewage disposal tank bottom 200 in the length direction.

The water area above the bottom of the long and narrow fish pond 3 between the middle upright posts 4 of the preset row direction 6 is set as a second water area 8, and the second water area 8 cannot be provided with the long-strip-shaped multi-span greenhouse aquaculture sewage disposal assembly 1 provided by the invention due to the obstruction of the plurality of middle upright posts 4, but the second water area 8 can be used for increasing the total aquaculture water body of the fish pond 3, can be provided with a water body circulation pushing mechanism, can be used for promoting the one-way flow of the aquaculture water body of the fish pond 3 between the first water area 7 and the second water area 8 by virtue of the drainage of the sewage guide wall 100, and is beneficial to slowing down the temperature change and the water quality change of the aquaculture water body of the fish pond 3.

The annular area between the side upright posts 5 and the adjacent middle upright posts 4 in the fish pond 3 is set to be a third water area 9, and the third water area 9 is not suitable for being provided with the long-strip-shaped multi-span greenhouse aquaculture sewage disposal assembly 1 provided by the invention, but the third water area 9 can be used for increasing the total aquaculture water body of the fish pond 3, can be provided with functional structures such as a sewage collecting tank 12, a second sewage pipe valve 272, oxygenation equipment, a water body circulation pushing mechanism and the like, and can be used for carrying out circulation exchange of aquaculture water body according to a preset scheme and the first water area 7 and the second water area 8, thereby being beneficial to slowing down the temperature change and the water quality change of the aquaculture water body of the fish pond 3.

The other water areas except the first water area 7 are not provided with the instant sewage disposal tank bottom 200, so that the culture manure cannot be discharged in time, and the instant sewage disposal tank is not used for aquaculture. In this way, the manure will not fall into the second 8 and third 9 waters, i.e. between the middle uprights 4 of the preset row 6, nor between the side uprights 5 and the adjacent middle uprights 4, and into the annular fish pond 3.

The second water area 8 and the third water area 9 are not provided with the long multi-span greenhouse aquaculture sewage disposal assembly 1 provided by the invention, so that the excrement is difficult to clean once falling into the water area, and the accumulated excrement becomes a cause for influencing the water quality deterioration of the aquaculture water.

In order to make the water pressures at two sides of the sewage guide wall 100 consistent, the water bodies at two sides are communicated, namely, the water bodies of the first water area 7, the second water area 8 and the third water area 9 are communicated, but the part communicated with the water bodies of the three water areas cannot transfer the excrement to the second water area 8 and the third water area 9 without the instant sewage disposal pond bottom 200 along with the water body exchange.

Filter means may be provided in the second water area 8 and the third water area 9 for filtering suspended fine dirt from the first water area 7. Photosynthetic organisms can also be cultivated in the second 8 and third 9 waters for the absorption of ionic harmful substances (e.g. nitrite etc.).

In the first water area 7, a net cage 300 may be provided, an aquatic animal is mainly raised in the net cage 300, and filter-feeding fishes are housed in the net cage 300 for balancing phytoplankton and zooplankton in the first water area 7.

In a bigger multi-span greenhouse 2, the area of the fish pond 3 is correspondingly large, in a big fish pond 3, aquaculture is carried out only in the first water area 7, the second water area 8 and the third water area 9 are in circulation exchange with the first water area 7, the ionic sewage concentration of the first water area 7 can be diluted, and the functions of maintaining the temperature stability and the water quality stability of the total aquaculture water body of the fish pond 3 can be achieved.

Natural ecological aquaculture is a type of aquaculture that relies on natural ecological purification to prevent the quality of aquaculture water from deteriorating and refusing to apply chemicals in the course of aquaculture, is a type of aquaculture that humans pursue, but is limited by the change of natural conditions of alternate seasons, which is not sustainable in the annual, intermittent, and has limited aquaculture productivity in time space.

In a larger multi-span greenhouse 2, the area of the fish pond 3 can be set to be large, and due to the arrangement of the multi-span greenhouse aquaculture pollution discharge assembly 1, the large fish pond 3 can become an artificial ecological lake for instant pollution discharge of all-season aquaculture under the protection of the multi-span greenhouse 2, so that all-season natural-simulated ecological aquaculture is realized, and the cultivation productivity in time space is improved.

The sewage guide wall 100 can enable the culture excrement particles in the first water area 7 to fall to the instant sewage disposal tank bottom 200 along the wall surface after colliding with the wall.
