Description
Technical Field
The utility model relates to an aquaculture technique, concretely relates to aggregation of batch production breed pond suspension organic matter.
Background
Compared with the traditional culture mode, the industrial circulating water culture mode has high industrialization degree, can realize the aquiculture with resource saving and environment protection, and respectively saves water and land by more than 90 percent. Since the 21 st century, with the development of novel bait technology with increasing aquaculture varieties and various varieties, the rapid development of the feed aquaculture industry is promoted. However, in these recirculating aquaculture systems for water conservation, suspended organic matter accumulates, clogging the biofilter, producing secondary metabolites, deteriorating water quality, increasing fish morbidity, and consuming dissolved oxygen in the water. According to statistics, the consumption of oxygen by large-sized farmed animals only accounts for 4.5 percent of the total oxygen consumption, while the respiration and the decomposition of dissolved and suspended organic matters of phytoplankton and small-sized zooplankton account for 50 percent (carp breeding pond) or 47.5 percent (eel breeding pond) of the total oxygen consumption.
The influence of suspended organic matter on fish is divided into three categories: one is lethal effect, and the fish individual can be directly killed by the overlarge concentration of the suspended organic matters; it is a sublethal effect, such as reducing growth rate and resistance to disease, interfering with embryonic differentiation; the third is the behavioral influence, such as the avoidance response of Oncorhynchus mykiss to the muddy water area. Therefore, the removal of suspended organic matters is the key to ensure the stable operation of the industrial recirculating aquaculture system.
At present, the technology for treating the breeding wastewater at home and abroad, particularly the treatment of suspended matters, is mainly divided into three types: namely physical, biological and chemical treatment methods. The characteristics of the tail water in an aquaculture system are: low pollutant concentration, low specific gravity of polluted solids, more viscous suspended organic matters, loose structure and large tail water flow, thus the treatment difficulty is higher. The suspended large particles in the aquaculture tail water mainly comprise residual baits, aquaculture biological excrement and the like, a mechanical filter (also called a micro-filter, such as a fixed sieve, a rotary drum type micro-filter, an arc sieve and the like) is used for treating particles of 60-200 mu m in actual treatment engineering, and the method is also a mode with more applications and better filtering effect. However, the mechanical filter has poor capability of treating organic suspended particles with loose structure and huge water quantity, so that the filter screen is easy to block to reduce the filtration efficiency, and the mechanical filter has more requirements on the setting of factors such as the specification of the filter screen, the rotating speed of the filter cylinder and the like. Meanwhile, the viscous suspended organic matter also increases the backwashing power consumption and the cost. Chemical treatment may cause secondary pollution, and biological treatment is susceptible to factors (such as fabric thickness, the number of vertical channels and the like) and is also related to the environment.
