Abstract

The invention relates to pond culture wastewater treatment and provides a facility for the treating pond culture wastewater, particularly relating to a facility for the overall treatment of the pond culture wastewater. The facility of the invention comprise a bio-pack, a wetland device and filter tanks, wherein the facility is characterized in that the bio-pack is barrel-shaped, the bottom part of the barrel-shaped bio-pack is filled with corallites, a honeycomb plate is arranged above the corallites, and biological filtration bulbs are arranged above the honeycomb plate; a spraying pipe connected with a water pump is arranged at the center of the bio-pack, and a conical surface spraying disc is arranged above the mouth of the spraying pipe; the wetland device is divided into three cells, a honeycomb-shaped water-permeable cement plate is arranged in each cell of the wetland device, cobbles, broken stones and yellow sand are arranged on the cement plate, and yellow iris, scirpus tabernaemontani and reed are planted in the wetland device; a front filter tank and a rear filter tank are respectively arranged on the front side and rear side of the wetland device; the bio-pack is connected to the bottom part of the front filter tank via pipes; water channels are arranged below the cement plate of the wetland device; and drain pipes are arranged at the upper part of the rear filter tank to divert the water into a fishpond. The invention is applicable in the treatment of the pond culture wastewater.

Description

technical field [0001] The invention relates to a breeding wastewater treatment system. Background technique [0002] At present, the commonly used aquaculture wastewater treatment devices include biological bags and filters. The biological bag is filled with biological filter balls, and the filter is filled with coral stones. The nitrification and denitrification bacteria in the filter material are used to degrade the organic matter in the water body and absorb the organic matter in the water body. suspended particles. [0003] There are two types of constructed wetlands for treating aquaculture wastewater: [0004] A surface-type wetland, the waste water overflows on the surface of the filler, which is the closest to the natural wetland, where most of the organic matter goes is completed by the biofilm that grows on the underwater stems and poles of plants. This kind of wetland cannot make full use of the plant root system in the filler layer, and the water quality treat...
