technical field

The invention relates to a device applied to the separation of aquaculture sediment and aquaculture water.

Background technique

my country has been a big country in aquaculture since ancient times. In 2018, China's aquaculture production exceeded 50 million tons, accounting for more than 78% of the total aquatic production. It has made a non-negligible contribution to my country's economic growth, but it is accompanied by serious problems. A series of environmental pollution problems, how to find a balance between economic and social benefits is a problem that everyone from farmers to national leaders has to face and consider.

The aquaculture sediment and the water body are directly discharged into the water body without separation, which will have a great impact on the environment. The content of N and P in the water body increases. When these pollutants are discharged into freshwater lakes with the water flow, it will lead to the phenomenon of "algae blooms" in freshwater water bodies. When entering seawater, it will lead to the phenomenon of "red tides", which will bring immeasurable effects to the environment. Therefore, the national environmental protection department has strictly regulated and rectified the phenomenon of "small scattered pollution", and has also issued the "Water Pollution Prevention and Control Law". , the comprehensive utilization of wastewater or the normal operation of harmless treatment facilities to ensure that the discharge of sewage meets the standards and prevent pollution of the water environment.

In the prior art, the separation process of sediment and water still remains in the traditional stage, and suction pump is directly used for suction, which has low sludge discharge efficiency, high mud content in effluent, and poor mud-water separation effect. In order to achieve the purpose of treating water quality, it is necessary to match a variety of corresponding pool types, which cover a large area and have high infrastructure costs. The system has low shock load resistance. If a large flow of aquatic sediment and water are mixed into the system, the effect of sludge discharge and water output will be greatly reduced.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in Figure 1, a device applied to the separation of aquaculture sediment and aquaculture water includes a plurality of culturing ponds and a treatment pond, and the treatment pond is separated into Temporary storage area, treatment area and equipment area. The temporary storage area is used to adjust the water volume and water quality, ensure the residence time of the incoming water, and emergency water storage when large quantities of water are influent. The upper part of the side wall of the treatment tank is provided with a connection to the temporary storage area. The water inlet tank is equipped with a grille, the side end of the partition A is open (that is, the front or rear opening of the partition A is a half partition), the upper part of the breeding pond is provided with a water supply pipe, and the bottom of the breeding pond is provided with a submersible sewage pump , the submersible sewage pump is connected to the input end of the water inlet tank through the sewage suction pipe, and several PVDF membrane bioreactors are arranged at intervals from left to right in the treatment tank. The suction port of the machine is located at the bottom of the treatment area. Aeration pipes are arranged below each PVDF membrane bioreactor. Several microporous aeration heads are evenly distributed on the upper side of each aeration pipe. Above each PVDF membrane bioreactor are suction pipes. Suction pipe, the lower part of the suction pipe is provided with a suction port, and the suction pipe is connected to the PVDF membrane bioreactor through the suction port.
