In this specific ecosystem of fishpond aquaculture water, exist the imbalance between material input and the output, the feed of throwing something and feeding has only small part to be digested and assimilated by fish, pass through the metabolism of fish and produce refuses such as urine, excrement, enter in the water body with the residual feed of not ingested by fish.Particulate matter can be divided into precipitable particulate matter (generally greater than 100 μ m) and can not deposit seeds thing (being generally less than 100 μ m).Harman research thinks that most finely ground particles sizes are at 6～20 μ m.The density of particulate matter has determined its state in water body.Chen etc. discover that circulating water system particulate matter mean density is about 1.19g/cm
3, and Timmons studies show that the particulate matter mean density in the tilapia breed is 1.05g/cm
3It is reported that the fish meta-bolites (containing residual feed) that enters water body accounts for about 80% of total daily ration, feeding quantity, remaining feed and meta-bolites will decompose rapidly under optimal temperature.Wherein account for 80% of total particulate quality greater than the precipitable particulate matter more than the 100 μ m, it may form the fine particle thing in broken back at aquaculture water, thereby the suspended particulate matter concentration in the increase water body, aquaculture water is produced pollution, thereby cause the rising of the complexity and the processing cost of water technology.Alabaster, Lloyd and Chen etc. have summarized the negative impact of particulate matter in the cultivating system, mainly comprise: directly damage the fish gill; Block biofilter; Ammonification produces ammonia nitrogen; Dissolved oxygen in the corrupt consume water of particulate matter.Enell and Lof, Ackefors and Enell, Gowen, Gowen et al., investigators such as Pillay, Costa-Pierce think that the removal of particulate matter is actually the primary goal in all circulating water culture system water treatment designs, remove the particulate matter that produces in the cultivating system timely and effectively, especially precipitable particulate matter is to reduce the cultivating system water pollution, improves the effective way of water treatment efficiency.
The removal of the particulate matter in the cultivating system is the treating processes of a solid-liquid separation.In aquaculture water, can be divided into gravity separation, filtration and foam separation three big removing methods according to the difference of removing method.Gravity separation is based on the precipitation principle, generally comprises flat flow precipitation, inclined tube (plate) formula precipitation and waterpower shunting etc.; Filtration treatment is the effect that reaches solid-liquid separation by screen cloth and granule medium etc., and various ways such as sieving, granule medium filtration and how empty media filtration are arranged; Foam separation then is to reach the solid-liquid separation purpose after adhering on the bubble by particulate matter.
