Description

Vertical integrated structure for pond water purification

Technical Field

The utility model relates to a pond water purification technical field specifically is a perpendicular integrated configuration of pond water purification.

Background

From the upper layer of the water body, the early stage of the 'water spinach-water cress' rotation mode (the water spinach planting stage) can obviously reduce TOC, Chl.a and NH in the cultivation water body of the black carps and the economic fishes₃-N、NO₂ ^--N、 NO₃ ^-The content of-N can obviously reduce TOC and NO in the water body at the later stage of rotation (cress planting stage)₃ ^-N, TP, the TOC, TN and TP content in the substrate of different breeding varieties can be reduced before and after rotation, Chinese herbal medicines (such as Houttuynia cordata Houttuynia cordiata Thunb, Polygonum cuspidatum cubidatum, mint Mentha halopthalyx Briq. and the like) can be considered in the selection of plant varieties in the rotation mode, and the effect of enhancing the immunocompetence of the gift tilapia can be achieved; the floating swimming and plant community structure of the aquaculture water can be improved by adding algae from the middle layer of the water body, the water quality can be effectively improved to a certain extent by combining the fillers from the middle layer and the lower layer of the water body, the growth of tilapia is promoted, the number of bacteria in the water body is reduced, the functional diversity of the microbial community of the water body is influenced, and a culture medium for immobilized microorganisms, EM (effective microorganisms) and enzyme substances capable of degrading organic matters can be thrown at the bottom.

For the aquaculture tail water restoration, the treatment can be generally carried out through three ways of physics, chemistry and biology, the biological filter has poor TP removal effect, and the removal effect of nitrogen and phosphorus is enhanced by matching with artificial wetland (such as surface flow). From theory and practice, bioremediation is a better way to solve the ecological environment pollution of the culture pond, and the mixed culture mode is favorable for purifying and restoring nitrogen and phosphorus in water quality, for example, the ternary mixed culture of weever, prawn and Taiwan red tilapia can effectively reduce the organic accumulation of residual bait to substrate and improve the water environment; the freshwater mussel and fish polyculture has better purification efficiency on the tail water of the main culture area. The water quality can be better purified in a breeding and circulating fishery mode (such as a water fish and vegetable system and a closed circulating water system), and scholars improve the environment of the prawn culture system through a shellfish and algae separate culture system; planting large algae (gracilaria) and other aquatic plants, stocking oysters and other shellfish, mullet, large yellow croaker, blacksea bream and the like, constructing and improving population structure, and inhibiting red tide generation (embodied as reducing nitrogen and phosphorus concentrations).

For most ponds, in-situ remediation is direct compared with ex-situ remediation, the operation is simple, the investment is less, farmers independently use various technologies, but how to organically combine water quality regulation and control technologies of upper, middle and lower layers of water bodies to carry out longitudinal ecological regulation and control on the water quality of the aquaculture pond and synergistically enhance the nitrogen and phosphorus removal effect is less to develop research of integration demonstration.
