The invention discloses a multi-stage ecological water tank and ecological pond combined system. The system comprises a ladder-type ecological water tank and an ecological pond, wherein the ecological pond is arranged in a river channel and comprises an enclosure which separates out an enclosure region from the river channel, a plurality of bionic aquatic plants are arranged in the enclosure region, and aeration holes corresponding to the bionic aquatic plants are formed in the lower parts of the bionic aquatic plants and are communicated with aeration devices; a water intake is formed in the ecological pond; the ladder-type ecological water tank comprises a first ecological water tank to an Nth ecological water tank which are sequentially arrayed from outside to inside and from high to low; the first ecological water tank is communicated with the water intake through a water intake pipeline; adsorbing fillers are arranged in the first ecological water tank, and filler-water plant-microorganism purification systems are arranged in a second ecological water tank to the Nth ecological water tank; a water outlet is formed in the bottommost ecological water tank in the ladder-type ecological water tank and is communicated with the ecological pond. By combining in situ regulation with abnormal-site regulation of the river channel, the black and odorous water quality is efficiently purified.

A method for positioning a light modulation element of a projector comprising: providing the projector including a first light modulation element unit having a first through a three light modulation elements, a second light modulation element unit having a fourth through a sixth light modulation elements, and a combining system for combining first image light supplied from the first light modulation element unit and second image light supplied from the second light modulation element unit and supplying combined light, positioning first light modulation element unit and second light modulation element unit such that color of combined light of color lights obtained from the first light modulation element, the second light modulation element, and the sixth light modulation element and combined by the combining system becomes a predetermined color.

The invention discloses an automatic pallet combination and separation system which comprises a pallet combination system, a pallet separation system and standard pallets. The pallet combination system comprises a level standard pallet conveying belt line I, an upward sloping conveying belt line at the pallet combination position and a level conveying belt line for combined pallets, wherein the three conveying belt lines are connected sequentially. A cargo conveying belt line I is arranged above the standard pallet conveying belt line I, the tail end of the cargo conveying belt line I is connected with a downward sloping pallet combination device, and the tail end of the pallet combination device is slant to the middle portion of the conveying belt line at the pallet combination position. The pallet separation system comprises a level pallet separation front conveying belt line, a downward sloping conveying belt line at the pallet separation position and a level standard pallet conveying belt line II, wherein the three conveying belt lines are connected sequentially. A cargo conveying belt line II is arranged above the standard pallet conveying belt line II, the front end of the cargo conveying belt line II is connected with a downward sloping pallet separation device, and the front end of the pallet separation device is slant to the middle portion of the conveying belt line at the pallet separation position. The automatic pallet combination and separation system is fast in conveying speed, stable in operation and low in noise.
