Abstract

The multifunctional sea water purification equipment comprises the purification pool and filter material placed in the purification pool, and the described filter material is formed from several pieces of water-cleaning clohtes which are parallelly sepaced and suspended, and the purification pool is divided into several purification filtering chambers by means of water-cleaning clothes. Said water-cleaning cloth has a row of vertical gaps which are cut according to a spaced width, and its two end portions and middle portion are equipped with connecting portion with a certain width, said water-cleaning cloth is a punched non-woven fabric, and its specific surface area is above 2000 sq.m / cu.m. Its purification process includes: fish farming pool, air float pool, multifunctional sea water purificiation equipment, oxygen-dissolving tank and fish farming pool.

Description

technical field [0001] The invention belongs to a seawater industrial culture water treatment method and equipment, in particular to a multifunctional seawater purification device and a treatment method. Background technique [0002] In the prior art, the filter material is generally placed in a biological purification tank, and an appropriate water purification agent is added. After a period of time, a layer of biofilm is formed on the surface of the filter material, and the sewage is purified when it passes through the biofilm. At present, there are mainly the following types of filter materials used in seawater sewage treatment purification tanks in the world: (1) Acrylic rubber silk filler, whose specific surface area is 50m 2 / m 3 (2) Plastic purification ball, its specific surface area is 300m 2 / m 3 or so; (3) Elastic functional filler, whose specific surface area is 300m 2 / m 3 about. The production of plastic purification balls and acrylic-based elastic filler...
