Description
Technical field
The utility model relates to the circulating water cultivation field, relates in particular to a kind of solid particulate matter and removes settler.
Background technology
The removal of solid particulate matter is the key factor in the circulating water culture system, the microbic mass that it is mainly derived from fish faeces, swill and comes off.The untimely removal meeting of solid particulate matter is to breeding water body and culture object generation influence greatly, is mainly reflected in following several respects: 1. directly damage the fish gill, reduce fish to the resistance of disease; 2. decomposable process increases the consumption of oxygen, easily causes the breeding water body anoxic; 3. biofilter is resulted in blockage, influence biological treatment effect, the bearing capacity of restriction system; 4. the concentration of harmful substance such as ammonia nitrogen in the mineralization increase system.
The gravitational settling method is to remove the simplest method of solid particulate matter, and its principle is to utilize solid particle to follow the density difference of liquid phase, and in static relatively fluid column, solid particulate matter deposits under the effect of gravity, reaches the removal purpose.Related facility, the device structure of gravitational settling method are simple, easy to operate, but usually only be applicable to and remove all bigger particles of proportion and particle diameter, and because the gravitational settling method needs enough hydraulic detention times to make the solid particulate matter precipitation, often the volume of related facility equipment is bigger, the input cost height, the processing time is long.
The solid particulate matter gravitational settling removal device that is applied at present in the circulating water culture system mainly contains hydrocyclone and perpendicular stream settling vessel, the basic principle of hydrocyclone is centrifugal sedimentation, the structure relative complex, and because relying on tangential water inlet to produce, it rotatablely moves, the internal flow state complexity is difficult to effectively control removal effect; Perpendicular stream settling vessel is simple in structure, floats on the settling vessel water surface but have a large amount of solid suspended particles, is difficult to sedimentation, influences deposition efficiency.
