The invention relates to the commodity fish culture and can be used for industrial cultivation of planting stock of coregonines in the basins and trays.

A device for fish cultivation, consisting of swimming pools, a pipe for draining water from the basin, plumbing for submission to the pool and filter [1, 2].

A significant drawback of the known device is that when replacing the filter, which changes several times along with the growth of larvae, it is necessary to catch all larvae from the pool and transplant them into another pool. During transplantation larvae injured, get stress, decreases their survival. In addition, every time you replace the filter, there is a need in Assembly and disassembly of the lantern frame, clamping devices and seals.

The technical result from the use of the invention is that when using the filter proposed design eliminates the need to catch larvae from the pool and transplant them to another pool when the filter is replaced. Increased survival of larvae and reduced labor times for fish farming.

Figure 1 shows the proposed device, a top view, figure 2 shows the lamp, side view.

The device consists of basin 1, the pipe 2 to drain water from the basin, plumbing for 3 innings of the water in the pool, the frame of the lamp 4, filter 5, the outlet pipe 6 and the flexible hose 7. Arrow 8 indicates the direction of flow of water.

Before you begin the unit on a rigid frame of the lantern put the filter from the mill sieves so that the nozzle of the torch entered the hole in the filter. Before filling the pool with water to the outlet pipe (not shown) put on a flexible hose. The second end of the flexible hose is put on the socket of the lamp. After this lantern is put on comfortable for the service location and the pool is filled with water. The water discharge from the basin is manufactured using the socket of the lamp, flexible hose, outlet pipe and pipes for water drainage. The water level in the pool is supported by means of the multilevel pipe (not shown).

When it is time to replace the lamp is lifted, removed from the socket of the lamp end of the flexible hose and put it on the socket of the lamp with a large pitch of the mesh in the filter. Lantern with a large pitch of the mesh in the filter put in its working position, i.e. at the bottom of the pool.

The proposed device has the following advantages over the prototype. There is no need to catch fish from the pool when replacing the filter, decreasing the volume of work involved in growing fish in tanks and trays, increasing the survival rate of fish as its not overload from one basin to another and not hurt. The advantages of the device apply and the simplicity of its implementation.

The proposed device is tested in Tyumen on the basis of LLC Stomach-Sign". Participated in the trials 2 swimming pools and 3 of the tray. The test results are positive. Such a device will find wide application in fisheries.

FIELD: water construction purification.

SUBSTANCE: invention relates to hydromechanisation namely to technology of purification and restoration of biological ponds of purification plants. Method of purification and restoration of biological ponds of purification plants includes intake of silt sediments with suction dredge from the bottom of multi-sectional pond and their transportation to sedimentation tanks. Pond is divided into two working areas of treatment, the latter is connected by means of additional input collector with sewage-water supplying canal in direction of sewage water flow motion, the former is blanked off, and construction of ground dam in area of purification is carried out as protective means. After that step-by-step purification of area is performed, for this purpose trench in silt sediments layer is sucked off by suction dredge, after that clarified water is pumped out and discharged into diversion canal. Silt sediments are collected in flowing state and transported either to silt sites or to sedimentation tanks. After that compressed silt sediments are dried by means of active ventilation and removed layer by layer as upper layer dries. After complete removal of silt sediments, base, bed of purified pond section, is restored, and said procedures are step-by-step repeated in successive purification of all sections of first area. Before purification of second working area round dam is erected again in last section of first working area of treatment, separating it from second working area, which is blanked off. First working area is joined to additional output collector with branch duct and opened, after which purification and restoration of sections of second working area are carried out. After finishing purification works ground dam, which was re-erected between two working areas, additional input and output collectors are removed, and second working area of pond is opened for functioning.

EFFECT: ensuring possibility of functioning of purification plants biological ponds without stopping them for purification.
