A hollow fibre membrane separation system is composed of membrane module, circulating tank and connecting pipeline. It features that the liquid inlet pipe is connected between circulating tank and membrane module for supplying raw material to membrane, and a working pump and the raw water flow controller and one-way chemical applying valve for washing said membrane module are installed to said liquid inlet pipe.

The invention discloses an automatic fish feeder. The automatic fish feeder comprises a loading hopper, a cylinder switch and a material containing mechanism, wherein the cylinder switch is verticallyconnected with an outlet at the bottom of the loading hopper, and a through hole is formed in the cylinder switch and is selectively communicated with an outlet of the loading hopper under the driving of the motor; the material containing mechanism can be used for containing fish food fed into water by the loading hopper through the cylinder switch and comprises a feeding ring, a telescopic rod and a feeding disc, and the feeding disc is connected to the part right below the feeding ring through the telescopic rod. According to the automatic fish feeder, the automatic feeding of feeds can berealized, so that the workload for manual feeding fish is reduced, and the satiation that the survival rate of the fish is reduced due to the forgetting of feeding is avoided; and after entering the material containing mechanism through a conveying pipeline, fish food can be fixed in a region delineated by the feeding ring and / or the feeding disc so as to form a fixed foraging site for the fish, so that efficient feeding of the fish is realized, the situation that the water quality of a fish tank is influenced when the fish food is not timely eaten because the food is not fed to a fixed site and drifted away all around is avoided, the replacement frequency of water in the fish tank is reduced, and the feeding cost lowered.

The invention provides a method for supplying glyptosternon maculatum initial feed. The method comprises the following steps: feeding hatched fairy shrimps after fry is hatched for 10 days and startsto come up; starting to feed rainbow trout initial feed after the fry is hatched for 20 days; starting to feed chopped tubificidae after the fry is hatched for 35 days; and starting to feed balls of mixture of rainbow trout initial feed, pig liver and tubificidae in the place with fries gathered after the fry is hatched for 60 days. The method can be used for successfully solving the problem of initial feed of glyptosternon maculatum fries, and the survival rate of fries can be remarkably increased.

The invention discloses a micropterus salmoides seedling transport case and a method for achieving micropterus salmoides seedling transportation. The transport case comprises a case body, a fry layer,an aeration layer and a filtering layer are sequentially arranged inside the case body from top to bottom, the fry layer and the aeration layer are communicated through a filter plate, and the aeration layer and the filter layer are separated through a partition plate; a tubular aerator, a first inclined plate and a second inclined plate are arranged inside the aeration layer, the higher ends ofthe first inclined plate and the second inclined plate are fixedly connected and are of a V-shaped structure, the lower ends extend in the opposite direction, the tubular aerator is arranged at the joint of the first inclined plate and the second inclined plate, and the tubular aerator is connected with a fan outside the case body. By adopting the structure, excrement, secretions and the like generated by fry can be completely supplied into the filtering layer from the fry layer and the aeration layer, the phenomenon that the water quality is affected due to the fact that excrement, secretionsand the like remain in the fry layer and the aeration layer for a long time is avoided, and fry health is threatened.

The invention discloses a special sampling base station for water quality detection, which relates to the technical field of water quality detection and includes a chassis, a storage battery, a controller, a sampling mechanism and a sampling terminal. The sampling mechanism includes a water distribution tank, a water distribution pipe, a water storage tank, a water distribution tank and a water distribution pipe The first water pump and the second water pump are connected between them; the water distribution pipe is connected to the sampling end through the first water pipe, and the first solenoid valve is installed on the first water pipe; the water distribution tank is connected to the plug-in pipe head through the second water pipe; One end is a tip, and the tip is inserted into a rubber stopper sampling bottle. There are a first pipe and a second pipe inside the tube, and a second solenoid valve is connected to the tube. The pipe is connected with a first one-way valve, the second water pipe is connected with the first pipe, the second water pipe is connected with a branch pipe, and the branch pipe is connected with a second one-way valve; the first solenoid valve, the second solenoid valve, the battery and the controller Evenly connected. The invention improves the convenience and quality of sampling.

The invention discloses preparation equipment for rapid aquatic plant rooting nutrition powder and a preparation method thereof and relates to the technical field of aquaculture techniques. The preparation equipment for rapid aquatic plant rooting nutrition powder comprises a rack, wherein a control box which is internally provided with a controller and a temperature controller is mounted on oneside wall of the rack through a support rack; a support plate which is horizontally arranged is fixed at the lower part inside the rack; a compacting machine is mounted in the middle position of the top of the rack; and a crushing machine is fixed on one side of the top of the rack. The preparation equipment is provided with a rotating structure, materials can be stirred by using a stirring rod and a connecting rod under the action of a rotating cylinder from different directions, furthermore, multi-direction material mixing can be achieved, the mixing efficiency of the materials can be improved, and thus the production benefit of the equipment can be increased; and in addition, in the material mixing process, a scraping rod is rotated together, so that the inner wall of a case can be scraped, resource waste caused by the situation that the materials are adhered to the inner wall of the case can be avoided, furthermore, resources can be saved, and the production cost can be lowered.

The invention provides a method for de-silting a lake and constructing a lake center island and belongs to a construction technology. The method comprises the following steps of: de-silting and dredging, transporting sludge, carrying out storage yard treatment, curing the sludge, discharging tail water and constructing the lake center island while de-silting. The method disclosed by the invention solves the problem that old problems of de-silted lake water happen again. The engineering cost is reduced, the work period is shortened and the secondary pollution is managed. The method has the characteristics of smaller occupied space, no transferring of pollutants, investment saving and good benefits. According to the method disclosed by the invention, the swampiness problem is solved, the water storage amount is increased, a land resource is increased, a wetland park is established and the pollution recycling is realized. The method is a practical and feasible good method for managing and beautifying the lake.
