(1) Choose the location of the galvanized canvas aquaculture pond, plan the layout first, dig the bottom of the fish pond, determine the location of the drainage and sewage pipes, and then bury it.
(2) The galvanized canvas fish pond is completely spliced on the ground, and the sewage outlet is opened on the canvas of the fish pond, which is the location of the embedded pipeline and fish toilet.
(3) Build three square canvas filtration sedimentation tanks at proper positions, and the functions of these three sedimentation tanks are sedimentation, coarse filtration and fine filtration. Fish pond excrement is discharged to these three sedimentation tanks through underground pipelines, which provides nutrients for vegetables in these ponds, and vegetables transform and absorb ingredients that are not conducive to farming, which is a complementary process. When the filtered water reaches the third pond, the water quality is already better.
(4) The last pond is used for purifying water and lifting water. Through some water purification microorganisms, the water quality is purified and reduced, and the reduced water can be recycled back to the culture pond and put into culture again.
Water quality is particularly important in aquaculture, and special attention should be paid to the construction of filtration and sewage system when building canvas fish ponds.
I believe many people have heard of the word "raw fish and vegetables". The growth of plants needs nutrients, and manure is a kind of organic fertilizer. A complete filtration system needs a sedimentation bin, a physical coarse filtration bin, a fine filtration bin, a biochemical bin and a clear water bin, as well as a circulating pump and a sterilization system, but today we are going to make a simple coarse filtration system for fish and vegetables, which needs a sedimentation bin, a physical coarse filtration bin, a biochemical bin and a clear water bin.
