Multifunctional circulating water treatment device

Abstract

A multifunctional circulating water treatment device comprises a shell, a filtering device and a drainage device and also comprises a potential energy device; wherein a water inlet and a water outletare respectively opened on the side wall of the upper and lower parts of the shell, a filtering device is arranged on the upper part in the shell to divide the interior space of the shell to an upperwater chamber and a lower water chamber, the upper water chamber is communicated with the water inlet, and the lower water chamber is communicated with the water outlet; the drainage device is connected with the filtering device and communicated with the upper water chamber; the water inlet is connected with a water inlet pipe, the water inlet part of the water inlet pipe is provided with the potential energy device, the potential energy device comprises an intake-pipe and a flow-increasing plate vertically arranged in the water inlet pipe, a gap is kept between the two sides of the flow-increasing plate and the wall of the water inlet pipe for inlet water pressurization, the wall of the intake-pipe arranged in the water inlet pipe is opened with a gas outlet port, the gas outlet port is back on the running water, one board of the flow-increasing plate faces the running water, and the other board is connected on the outer wall of the pipe corresponding to the gas outlet port on the intake-pipe. The potential energy device greatly saves energy consumption while realizing favorable waterbody dissolved oxygen effect.

Description

technical field [0001] The invention relates to the field of aquaculture water circulation treatment technology, in particular to a multifunctional circulating water treatment equipment, which is mainly used for raising shrimps and fish in high-level ponds, and can also be used for growing and raising seedlings in seawater and freshwater industrial circulating water, and raw water for aquaculture Treatment, oceanarium and aquarium circulating water treatment, etc., can also be applied to seafood, river fresh transportation and wholesale market holding system, scientific experiments and other water treatment systems. Background technique [0002] Circulating water in seawater, freshwater fish, shrimp, and shellfish culture requires a variety of treatment processes before it can be recycled. These treatment processes include mechanical filtration, foam separation, oxygenation, biochemical treatment, sewage discharge, sterilization, backwashing and other treatment steps. , the ...

Problems solved by technology

[0002] Circulating water in seawater, freshwater fish, shrimp, and shellfish culture requires a variety of treatment processes before it can be recycled. These treatment processes include mechanical filtration, foam separation, oxygenation, biochemical treatment, sewage discharge, sterilization, backwashing and other treatment steps. , this treatment step is completed by water treatment equipment with different functions, therefore, the function of the existing aquaculture water treatment equipment is relatively single

[0003] In the prior art, the circulating water treatment system is composed of the above-mentioned various water treatment equipments that realize their respective functions. The treatment system uses a large number of water treatment equipment, which makes the whole system bulky and occupies a large area; (2) Since the installation technical standards of each water treatment equipment are different, the requirements for the installation site are relatively high; ( 3) The investment cost of the water treatment system remains high due to the disadvantages of a large num
