FIG. 1 is a schematic structural diagram of a step-by-step biological control type ecological purification pond system.
Detailed Description
The invention is further described with reference to the following figures and specific examples.
As shown in fig. 1, the step-by-step biologically-controlled ecological purification pond system comprises a water inlet end 1, a water outlet end 8, a zooplankton filter feeding area 2, a benthonic animal scraping area 3, a fish feeding area 4 and an aquatic plant water quality stabilization area 5; sewage flows in from the water inlet end 1, sequentially flows through the zooplankton filter feeding area 2, the zooplankton scraping area 3, the fish feeding area 4 and the aquatic plant water quality stabilizing area 5, and flows out from the water outlet end 8.
The zooplankton resting eggs are thrown in the zooplankton feeding area 2; benthonic animals such as river snail, freshwater mussel and chironomid larva are thrown into the benthonic animal feeding area 3; the fish feeding area 4 is fed with fishes mainly including silver carps and spotted silver carps; aquatic plant young plants, mainly aquatic plants and hydroponic vegetables, are loaded in the aquatic plant water quality stabilizing area 5.
The zooplankton filter feeding area 2 and the zooplankton scraping area 3 are separated by a water permeable grid 6, and the water permeable grid 6 is made of non-woven fabrics; the benthonic animal feeding area 3 and the fish feeding area 4 as well as the fish feeding area 4 and the aquatic plant water quality stabilizing area 5 are separated by gauze 7.
The zooplankton filter feeding area 2 and the aquatic plant water quality stabilizing area 5 are constructed along the shore, and the water bodies of the benthonic animal scraping area 3 and the fish feeding area 4 have a certain depth. Thus, the depths of the zooplankton filter feeding area 2 and the aquatic plant water quality stabilizing area 5 are different from the depths of the benthonic animal scraping area 3 and the fish feeding area 4. The depths of the zooplankton filter feeding area 2 and the aquatic plant water quality stabilizing area 5 are 1.5-2.0m, and the depths of the zooplankton scraping area 3 and the fish feeding area 4 are 2.5-3.0 m.
The hydraulic power of the sewage stays for at least 3 days in each zone.
The water inlet end 1 and the water outlet end 8 are provided with water inlet and outlet pipes which are UPVC pipes.
And the automatic aerator is also arranged and used for aerating oxygen into the pond so as to prevent adverse effects caused by oxygen deficiency of the purification pond due to uncontrollable factors such as weather and the like.
By utilizing a step-by-step biological control technology, the pond is divided into 4 ecological function purification areas through permeable enclosing grids and gauze on the basis of natural water bodies such as a conventional pond. After the sewage enters a purification function area of the system after being collected and regulated by a water inlet end 1, an ecological preparation 9 with sepiolite and active diatomite as main components added in the purification function area can effectively improve the habitat conditions of a water body in the system, in a zooplankton filter feeding area 2, zooplankton communities can filter and feed micro organisms such as algae and suspended particles, in a zooplankton scraping area 3 comprising various producers, consumers and decomposers, sewage components such as the settled particles and the soluble nitrogen and phosphorus can be effectively scraped through a natural ecological process, in a fish feeding area 4, the sewage components such as the algae and the suspended particles can be effectively removed through a direct feeding function and an indirect biological transfer function of fish, and in an aquatic plant water quality stabilization area 5, aquatic plants can naturally adsorb, absorb and fix, The conversion can effectively get rid of dissoluble nitrogen phosphorus and dissoluble organic matter, and the zooplankton strains the biological individual in eating the district 2 littlely, and the enclosure 6 that permeates water that passes through the aperture is less separates with the zoobenthos area of scraping 3, and the fish is ingested the district 4 and is scraped the biological individual in eating the district 3 with the benthos and is great relatively, separates through gauze 7. The sewage flows out of the system through the water outlet end 8 after being acted by the purification functional area controlled by the step-by-step organisms. After sewage flows through the purification functional areas step by step, suspended particles, settled particles, algae and soluble nitrogen, phosphorus and organic matters in the sewage can be efficiently removed.
The working principle of the step-by-step biological control type ecological purification pond system is that different species in the ecological purification pond are in different nutrition levels in a food chain due to different types and sizes of food, feeding places and biological rhythms, and have unique ecological niches. Zooplankton communities can filter and eat micro organisms such as algae and suspended particles, the zooplankton communities comprise various producers, consumers and decomposers, and sewage ingredients such as the settled particles and soluble nitrogen and phosphorus can be effectively scraped through a natural ecological process. The second-level consumer and the third-level consumer of the food chain formed by the fishes can effectively remove sewage components such as algae, suspended particles and the like through a direct ingestion function and an indirect biological transfer effect, and the water plants can effectively remove soluble nitrogen and phosphorus and soluble organic matters through natural adsorption, absorption, fixation and transformation effects.
