Description

A kind of high-concentration waste sewage aerating atomization and vaporization treatment technology

Technical field

The present invention relates to a kind of high-concentration waste sewage aerating atomization and vaporization treatment technology, belong to high-concentration sewage processing technology field, especially carry out the solidification treatment of pollutent for the high-concentration sewage not recycling value.

Background technology

Along with the fast development of national economy, water resources is day by day in short supply, and all trades and professions advocate water-saving technology energetically, and improve sewage reuse techuique, sewage generation is corresponding minimizing also, but the generation of high-concentration sewage too increases difficulty and the cost of process.

The Tengger desert sewage lagoon problem occurred for 2014 is an example the most obvious, the sewage that a large amount of pollution concentrations that several chemical plant of Teng Geli industrial park, Alashan League produce are very high, the illegal sewage evaporation pond of setting up in desert because its processing cost is high, thus cause the grievous injury that cannot make up environment.

To the process of high-concentration sewage, relevant enterprise and researcher have paid a large amount of painstaking effort, have developed the high density water technologies such as evaporation, filtration, ionization, for very large contribution has been made in sewage disposal.

Although high-concentration sewage treatment technology is many, there is certain limitation.

201320863733.9), the treatment process (patent No.: 201410071502.3) need warm air to carry out sewage evaporation of low-temperature evaporation high-concentration sewage as the treatment unit (patent No.: of: a kind of saline sewage, need to provide high heat energy, mainly lay particular emphasis on energy-conservation aspect; Technology for treating super heavy oil sewage through heat pump evaporation method (200910219921.6) mainly processes super thickness sewage; Based on the process for treating high-concentration sewage of reverse osmosis, (patent No.: disposing of sewage 201410072039.4) with reverse osmosis, shortcoming can only be filtered particulate matter.

Based on the different shortcomings that the scheme of above-mentioned incomplete statistics exists, contriver develops a kind of high-concentration sewage treatment facility, for sewage disposal provides an effective approach.Be mainly used in the dense salt waste water of the discharges such as desulfurization, chemical industry, papermaking, power plant, when having no recovery value but cannot discharge, the salt taked, water separation technology, through electroprecipitation, filter hardness and adopt after turbidity that aerating atomization and vaporization mode carries out salt, water is separated, thus realizes zero blowdown.

Summary of the invention

In order to solve the problem of high-concentration sewage process, the salt that the present invention takes, water separation technology, then after electroprecipitation, filtration hardness and turbidity, adopt the high-concentration sewage treatment technology that aerating atomization and vaporization mode carries out salt, water is separated.

The present invention implements by following technical solution:

The major portion of high-concentration waste sewage aerating atomization and vaporization treatment technology is gas-vapor mix atomization jetting device, comprises water inlet pipe (002), water control valve (003), inlet pipe (005), reducing pipe (006), spray tube (008).

Also need the equipment such as supporting detention tank, sewage water filtration pond, water pump, air pump.

Detention tank is condition setting environmentally, and area, at least at tens of square meters, is typically provided to rectangle, and gas-vapor mix atomization jetting device is placed in one end of detention tank, and spray tube (008) is towards the other end.

From the sewage that detention tank takes out, through the filtration in sewage water filtration pond, the water-fast solid matter of filtering, then the high velocity flow (001) produced after water pump pressurization is transported to water inlet pipe (002), meanwhile, the high velocity air (004) that air pump produces is transported to inlet pipe (005).

Water control valve (003) is the flow velocity and the turbulence intensity that regulate high velocity flow (001).

As everyone knows, water can be evaporated in air after obtaining certain energy, and the pollutent that grades of the salt in sewage then not easily evaporates.

High velocity flow (001) adjustment through water control valve (003), mix with high velocity air (004), form mixing water air-flow (007), through reducing pipe (006), spray from spray tube (008), form atomized steam, moisture evaporates rapidly and dissolves into the air, and not evaporable pollutent and the unevaporated sewage of part fall into detention tank.

Sewage is through the continuous rapid evaporation of above-mentioned circulation, and the concentration of wastewater in detention tank is more and more higher, finally forms solid waste, is convenient to recycling, reaches zero release of pollutant.

The present invention has obvious advantage compared with the sewage treatmentmethod adopted at present: what produce after 1, processing is solid waste, can recycle; 2, sewage zero-discharge can be accomplished; 3, increase atmospheric moisture after sewage evaporation and be conducive to environment, accomplish utilization of waste material.
