II. Equipment principle

It is a comprehensively solve aquatic water organic PM's filtering separation, water purification and water quality automatic detection and other aquaculture water purification, provides effective models in terms of efficiency, energy saving, integrated degree for our country's aquaculture purification technology. Its main treatment process uses physic-chemical method, chemical method, gas flotation method, filtration adsorption method and other traditional handicraft organically combined to design, mainly remove turbidity, suspended solids, colloids and other impurities in the water. It uses Solid - liquid or liquid - A method of liquid separation, its principle: The volume of air drawn through the air compressor to dissolve in a sealed tank, by releaser's sudden decompression to quick release, resulting in a large number of fine small bubbles, in the float process, a fine small bubbles adhere to waste water's molecule and slightly soluble content which its density close to water, resulting in situation of global density less than water, and buoyancy make it rise to the surface. It separates tiny suspended solids, alga and Micro polymers in the water, separation and recovery of suspended oil and emulsified oil in the oily wastewater, separation and recovery of ionic state material, such as surface active material and metal ions.

III. Equipment Characteristic

It sets flotation, filtration, adsorption in one, has a good effect on removal of oil water separation, suspended solids, COD、BOD, the general wastewater pass through treatment system can meet emission standards. Its main treatment process uses physical-chemical process, combinational designs chemical method, gas flotation method, filtration adsorption method and other traditional mature technology, has characteristics of simple and reasonable process, wide adaptation, compact structure, easy transportation and installation, simplicity of operator, stable and reliable property. The entire apparatus consists of sewage pumps, metering mechanism, combination of dosing device, reactive tank, and air floating system, sand filters, activated carbon adsorption column and electric control system. According to the size and ease of installation capacity, equipment is entirely or separation of the welded assembly.
