2. Water intake and drainage process of the farm

3, each part of the production system transformation plan

(1) Water source and pumping station

Aquaculture water comes from Sui-Tang River, with abundant water and good water quality, which fully meets the requirements of aquaculture. This plan does not consider the treatment of aquaculture source water, but the pumping stations need to be rebuilt (two) and built (three). The original water supply equipment can not meet the water supply requirements, and all of them need to be reinstalled to meet the water supply requirements.

(2) Water inlet system

In this scheme, a new water inlet channel is designed for the aquaculture pond, and the water is taken from four pumping stations on site. The water inlet channel is of groove structure and cast-in-place reinforced concrete, with an inner diameter of 80 cm wide and a depth of 80 cm and a total length of 900 meters. The water used in the seed incubation workshop is taken from the adjacent pond (as the water storage reservoir of the seed incubation workshop), lifted by a special water pump, and sent to the high water tower through the mechanical sand filter for water supply in all parts of the workshop.

(3) Renovation of aquaculture ponds

At present, the layout of aquaculture ponds in Fengze freshwater fish farm in Jinshan District is fairly regular. However, due to aquaculture siltation and shallow water depth, there are serious phenomena of pond bank collapse and erosion, and the original pond slope protection is seriously damaged. It is planned to carry out dredging, reshaping and local new slope protection for the inlet and outlet, and transform the original slope protection and inlet and outlet facilities. The width of the reconstructed pond bank is 3-5 meters, and the pond bank is seriously damaged.

(4) Seed production workshop

The original incubation workshop of Fengze Freshwater Fish Seed Farm in Jinshan District has outdated facilities and backward production technology, which can no longer meet the needs of modern freshwater fish seed production, so it was demolished and built in another site. The newly-built incubation workshop is 760m2, with a span of 16m, a length of 53m, and a height of 2.8-3.5m, and is a workshop with color steel plate structure. The workshop is divided into area A, area B and area C, and area B has a fish-loving pond, a spawning pond and a fertilized egg debonding pond. Plan and design according to process requirements, and provide corresponding operation rooms. In order to save water, the fish pond and the spawning pond are designed with separate circulating water loops, and mechanical filtration and jet aeration are also considered. Plan a 4m-wide operation site and build a special warehouse between A and B; A 4m-wide operation site and a special laboratory are planned in Area B and Area C, and ventilation, lighting and heat preservation should be considered in the freshwater fish incubation workshop. The newly-built Penaeus vannamei seedling workshop is 800m2, with a span of 16m, a length of 50m and a height of 2.8-3.5m. The workshop is designed to be 3 meters wide, 6 meters long, 1.2 meters ... semi-buried (the ground height is 0.8m), water enters from the north and south sides of the workshop, and there is a drainage ditch with a width of 0.8m and a depth of 0.6m in the middle, which is connected with the ecological drainage ditch from the west. At the same time, the workshop is designed with two high-level dark sedimentation tanks and two brine tanks, which are 3m wide, 6m long and 3m deep. Design a temperature-regulating water tank with a width of 3.5 meters, a length of 6 meters and a depth of 1.2 meters, and it is equipped with corresponding water supply and drainage pipes.

(5) Drainage system

Design and build a new drainage system for fish farms. The drainage system consists of open ditches, open channels, water conveyance culverts, river wetlands, aquaculture wetlands and paddy wetlands. The pond is drained upward. The width of the open drain is more than 8 meters, and the water flow speed is not less than 500 cubic meters per hour. The open drain is 980 meters long, 80 centimeters wide and 80 centimeters deep, cast-in-place reinforced concrete, and the water flow speed is not less than 300 cubic meters per hour.

(6) Ecological wetland system

Ecological wetland system includes drainage ditch ecological wetland, aquaculture wetland, river ecological wetland, paddy field ecological wetland and so on. The total area of the area is 24 mu, and there are more than 40 mu of paddy fields and river wetlands outside the area.
