Device capable of removing micro-plastic particles in water in ditch water inlet type seawater culture pond

Abstract

The invention discloses a device capable of removing micro-plastic particles in water in a ditch water inlet type seawater culture pond. The device comprises a filter box embedded in a ditch and not submerged by water flow, wherein a plurality of filter cavities allowing water to be fed from the front end and discharged from the rear end are formed in the filter tank, and a front sundries stopper,a water flow reducer, a first-stage funnel-type primary filter, a second-stage funnel-type primary filter, a first-stage grid microfilter, a second-stage grid microfilter, a third-stage grid microfilter and a rear biological stopper are arranged in each filter cavity from front to back sequentially. Compared with the prior art, the device has the advantages as follows: (1) a novel water inlet pipeline system is not needed to be rebuilt, the adaptability is wide, the universality is better, and the cost is saved; (2) the micro plastic particles in the water in the culture pond can be effectively removed; (3) modular design is adopted, so that the device can be disassembled, flushed or replaced conveniently; (4) the frequency of replacing or flushing filter screens can be reduced; (5) use is convenient, the cost is relatively low, and maintenance is simpler.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a device capable of removing microplastic particles in the water body of a ditch-inlet type mariculture pond. Background technique [0002] Plastic products are widely used in industry, agriculture and daily life because of their good performance. According to statistics, in 2016, the global plastic consumption reached 500 million tons, while my country's total output of plastic products reached 77.17 million tons, making it the world's largest plastic producer. The extensive use and random discarding of plastics has led to a large amount of accumulation in the environment. Among them, an estimated 8 million tons of plastic waste have been discharged directly into the water, seriously affecting the ecological security of the water environment. Discarded plastic products form fine plastic particles under the action of water flow, wind force, tide and other mechanical forces, ultraviole...
