Description

Fish pond circulating water multifunctional solid dirt separator

Technical field:

The invention belongs to the industrial culture water treatment technology, and is a multifunctional solid dirt separator for circulating water in fish ponds.

Background technique:

Before the present invention was made, the separation method of the solid dirt particles in the water body of industrial farms at home and abroad: mainly rely on filter bags, sand filters and sedimentation methods; The larger particles (0.1um to 3.3μm) in the water body, the fine particles in the water body are difficult to absorb, and the filter bag has to be cleaned and replaced manually every day; the sand filter is equipped with a filter sand layer in the tank, and by retaining a certain amount of particles The diameter of the particles can achieve the purpose of removing particles. Since the flow rate of the water flow is in a state of gradually decreasing with the increase of the intercepted matter, it is necessary to adjust the flow rate valve at any time to control the flow rate. The particles that have been intercepted will waste a lot of water. At present, the water treatment process of industrial fish farming in my country mainly adopts manual cleaning and water exchange methods to improve, but these methods also cause a lot of waste of water supply, a lot of energy consumption, and the water treatment effect is poor, which increases the load on the follow-up water treatment work . The separation method of solid dirt particles in the water body of foreign factory farms mainly adopts the method of sedimentation to separate the dirt particles in the water body; the sedimentation type dirt particle separation is that the breeding wastewater flows into the sedimentation tank for sedimentation, and the pool water flows out to the water. The separation of larger particles (10um to more than 15um) is a rapid separation method, but it can only discharge large particles, most of which are sedimentable solid dirt particles. This kind of separation has higher requirements on the water flow of the system, about 10% of the total water flow. In order to improve the separation efficiency, grids can also be added in the sedimentation tank to increase the interception area, improve the separation efficiency, and separate smaller particle pollutants, but these methods are difficult to use in the treatment of industrialized aquaculture circulating water.
