Pond culture biological membrane water purifier with bacteria strains and culture mediums and water purifying method

Abstract

The invention discloses a pond culture biological membrane water purifier with bacteria strains and culture mediums. The pond culture biological membrane water purifier comprises a support frame, wherein a motor is arranged on a vertical rod in the middle part of the support frame and is connected with a speed reducer; the speed reducer is connected with one end of a transmission shaft, and the other end of the transmission shaft is fixedly arranged on the support frame through a bearing block; a rotary drum is fixedly arranged on the transmission shaft; a plurality of water permeating holes are formed in the side surface of the rotary drum; a plurality of porous plastic balls are arranged in the rotary drum, and each porous plastic ball is filled with a carrier which is soaked with probiotics and corresponding culture mediums; a support rod is arranged on the support frame, and is vertical to the direction of an extension line of the transmission shaft; the support rod extends out of an outer framework of the support frame; a cylindrical floating body is arranged at the end part of the support rod; the diameter of each porous plastic ball is greater than the diameter of each water permeating hole. The pond culture biological membrane water purifier has the advantages that the cost is low, the effect is quick, the maintaining time is long, the stability is good, the operability is strong, the outside interference is small, and the like; the purifying effect of pond culture water is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a biofilm water purifier and a water purification method for pond culture with its own bacteria species and culture medium. Background technique [0002] my country is the country with the largest pond fish farming area and the longest history in the world. The sea and freshwater ponds have a farming area of ​​more than 5 million hectares and have a history of thousands of years of fish farming. However, the traditional breeding mode restricted the output. At that time, the yield of the main pond was only more than 300 catties per mu. In the early 1970s, as the only fishery machinery research institution in my country, Shanghai Fishery Machinery Institute successfully developed the first 7.5 kW impeller aerator in my country in 1972 after in-depth investigation and research in fishing areas. The successful development and large-scale promotion of the impeller typ...

AI Technical Summary

Problems solved by technology

But the duration is limited, self-propagation is affected by factors such as organic matter in pond water, and the effect of purifying water quality is greatly reduced

If you want a good water purification effect, you need to continuously pour it into the pond, which is time-consuming and expensive, and the effect is greatly affected by the outside world
