Embodiment Construction

[0019] The pond bottom material collection and purification system of the present invention is composed of a square or circular culture pond, a surge machine (sewage collection), a sewage collection pit, a protective cover plate, a sewage collection pipe, and a sequencing batch reactor activated sludge process (sequencingbatchreactoractivatedsludgeprocess, It is composed of SBR pool for short), water delivery equipment and return water pipeline. The aquaculture pond is generally 3-7 acres, and a 1.1KW surge machine is installed in the center of the pond; a sewage collection pit with a diameter of about 0.5-2.0m is installed at the bottom of the pool directly below the wave machine, and the depth is about 0.5m; the top of the pit A circular protective cover plate is installed slightly higher than the surrounding pond bottom 5-10cm. The diameter of the cover plate is slightly larger than the diameter of the sewage collection pit; a UPVC pipe or corrugated pipe with a diameter of ...

Abstract

The invention discloses a breeding pond bottom quality treatment system. A surge machine is installed in the center of the pond, a sewage collection tank is arranged below the surge machine, and a protective cover is installed on the upper part of the sewage collection tank. When the surge machine is running, the The pond water rotates, and the centrifugal force generated will collect the sediment scattered at the bottom of the pond into the sewage collection tank under the protective cover, and then transport it to the sequencing batch activated sludge reaction tank outside the pond through the sewage collection pipe connected to the sewage collection tank Among them, the sequence batch type activated sludge reaction tank has a blower aeration pipe, the blower aeration pipe is externally connected to a fan, and the middle and upper part of the sequence batch type activated sludge reaction tank is equipped with a low-flow water delivery device , the relatively clean water in the upper part of the sequencing batch activated sludge reaction tank is transported to the pond through the return pipe connected to the water delivery equipment.

Description

technical field [0001] The invention belongs to the technical field of pond cultivation, and in particular relates to a bottom quality treatment system of a cultivation pond. Background technique [0002] Most pond farming in my country adopts traditional farming methods, and a large amount of feed and fertilizers are often required to be invested in the breeding process. Most of these substances are deposited to the bottom of the pond in the form of fish and shrimp feces and residual bait to form the substrate. Because the decomposition of organic substances in the substrate requires a large amount of oxygen, an anoxic and anaerobic environment will be generated at the bottom of the pond, seriously affecting At the same time, a large amount of nutrients such as nitrogen and phosphorus contained in the substrate cannot return to the pond water body to form primary productivity, resulting in waste of resources. In recent years, with the increasing social impact of aquacultur...
