Description
Technical Field
The invention belongs to the technical field of cultivation water treatment equipment, and particularly relates to a novel box-type cultivation micro-filter.
Background
The industrial circulating water cultivation mode is accepted by people gradually and is increasingly applied to production practice due to the advantages of environmental friendliness, energy conservation, water conservation and the like. The industrial circulating aquaculture system (RAS) can provide a controllable environment, the size of the system is not limited by environmental conditions, the growth speed of the cultured aquatic products can be controlled, and even the yield can be predicted. Compared with the traditional cultivation mode, the circulating water cultivation production mode can save 90-99% of water consumption and 99% of land occupation per unit yield, and hardly pollutes the environment. Water treatment is the most important part of the industrial circulating water culture mode, and the water treatment modes comprise physical treatment and chemical treatment. The physical method comprises the steps of utilizing various filter materials with different pore sizes, removing impurities in water by utilizing an adsorption or separation mode, wherein the important adsorption mode is to use activated carbon for adsorption, and the separation method is to pass water through the filter materials so that the impurities with larger volume cannot pass through, and further clean water is obtained. At present, when a plurality of industrial aquaculture or ornamental fishes are cultured, water circulation treatment is often needed, so that water in a cultured pond or container is subjected to microfiltration continuously, and the phenomenon that water quality is affected by accumulation of wastes generated in aquatic life is avoided, and the survival and propagation of aquatic animals are affected. The existing water circulation system micro-pore screen is fixed on a rotary drum type filtering device, and the purification device for solid-liquid separation is realized by intercepting solid particles in the culture water body. The working principle is that when the culture water body passes through the microporous screen on the rotary drum, under the rotation action of the rotary drum, the solid wastes in the culture water body are separated, so that the water body is purified, and the purpose of recycling is achieved. At present, the water level of many farms is deep, and the filter tank is already manufactured, so that the filter screen is inconvenient to replace in the later stage due to poor installation. In order to solve the problems, a novel box-type micro-filter for cultivation is provided.
