Water suspension filtering bed

Abstract

The invention discloses a water suspension filtering bed which comprises a filtering bed body and a filtering net (10). The filtering bed body comprises a first baffle (1), a second baffle (2), a third baffle (3) and a fourth baffle (4). The first baffle (1), the second baffle (2), the third baffle (4) and the fourth baffle (4) define a cavity. The filtering net (10) is arranged in the cavity and fixed to the four baffles. The upper portion of the third baffle (3) and the upper portion of the fourth baffle (4) are provided with water outlets (11) for discharging filtered water out. According to the water suspension filtering bed body, the cavity for water to flow is defined by the baffles, the corresponding baffles are provided with the water outlets for discharging the filtered water, the filtering net is further fixedly arranged in the cavity, the suspensions in the water can be filtered out, the surface area of the filtering net is enlarged, the water passing amount is large, operation is convenient, and the application range is large.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a filter bed for suspended matter in water. Background technique [0002] Suspended matter refers to solid matter suspended in water, including insoluble inorganic matter, organic matter, mud sand, clay, microorganisms, etc. 80-90% of suspended matter is less than 30um, and the content of suspended matter in water is the main cause of water turbidity. It is also one of the indicators to measure the degree of water pollution. At present, my country's fishery and aquaculture has begun to shift from traditional extensive farming to large-scale, high-density, factory farming. During the fish farming process, a large amount of residual bait, fish manure and other substances are produced. If they cannot be filtered out in time, these substances will be in the form of Suspended solids in water exist in the form of suspended matter, which will cause harm if they stay for a long time.

Problems solved by technology

At present, my country's fishery and aquaculture has begun to shift from traditional extensive farming to large-scale, high-density, factory farming. During the fish farming process, a large amount of residual bait, fish dung and other substances are produced. If they cannot be filtered out in time, these substances will be in the form of Suspended solids in water exist in the form of suspended matter, which will cause harm if they stay for a long time. After oxidation, ammonia nitrogen will increase, and the toxicity in water will increase. In addition, the reproduction of bacteria will also increase, and the dissolved oxygen in water will decrease accordingly. Fish disease outbreaks, the current removal of suspended solids is commonly used sand filter, screen filter, flat filter and automatic cleaning filter filter, but there are problems such as large area, easy to block, complex structure, high cost, high energy consumption, etc.
