Embodiment Construction

[0031] In this embodiment, the filtration system for removing suspended solids in the aquaculture system includes a microfilter and an automatic control device. figure 1 It is a structural schematic diagram of the microfiltration machine of this embodiment, which includes a machine cover 1, a box body 2, a central support shaft 3, a filter drum 4, a backwash pipe 51, a nozzle 52, and a backwash water pump (not shown) , collecting dirt hopper 6, time relay (not shown), motor (not shown), cycloidal pinwheel reducer 71, gear set 72, water inlet pipe 81 and drainpipe 82, main body material is stainless steel. The central support shaft 3 is a hollow non-rotating part, which is fixed in the box body 2. The filter drum 4 is rotatably connected with the central support shaft 3 through two sliding bearings, so that the filter drum 4 can be centered on the axis of the central support shaft 3. The center rotates, and the outer surface of the filter drum 4 is equipped with 3 pieces of fil...

Abstract

The invention provides a method and a filtering system for removing solid suspended particles from an aquaculture system. The method comprises the following steps of: continuously injecting aquaculture waste water which contains the solid suspended particles into a filter rotor drum of a micro-filter from a water inlet pipe; discharging the waste water from a drain pipe after being filtered by a filter screen of the filter rotor drum; intermittently driving the filter rotor drum to rotate while starting a back washing device to wash the filter screen so as to wash away the particles on the filter; and stopping the rotation of the filter rotor drum and the washing of the back washing device after finishing washing. The filter system comprises the micro-filter and an automatic power supply control device, wherein the micro-filter comprises a cover, a box, a center support shaft, the filter rotor drum, the back washing device, a back washing water pump, a dust collecting funnel, a motor, a transmission device, the water inlet pipe and the drain pipe. The filter rotor drum and the back washing device are intermittently started and the filter screen is back washed so the energy consumption of the micro-filter can be effectively decreased and the filtering effect is improved.

Description

technical field [0001] The invention relates to the field of aquaculture water treatment, in particular to a method for filtering and removing suspended solids (Suspended solids, SS) in an aquaculture system and a filter system used. Background technique [0002] There are often many solid suspended particles in the aquaculture system. These solid particles are mainly composed of three parts: fish feces, residual bait and bacterial biomass. The main source is feed. The removal effect of solid suspended particles in aquaculture system directly affects many important factors such as fish growth, biological purification effect, system configuration and operating cost. [0003] Micro screen drum filter is currently the most widely used coarse filtration device, and is now also used in the removal process of solid suspended particles in aquaculture systems. Chinese patent application 02158869.4 discloses a microfilter used for seawater aquaculture water treatment, which has a fi...
