Description
Technical field
The present invention relates to a kind of wastewater processing technology, relate to specifically a kind of high-concentration industrial-water novel treatment technology.
Background technology
At present, in Industrial Wastewater Treatment field, the especially waste water of high density, high saliferous, high difficult degradation, does not also have comparatively effective, general technology and method to process it, because the limitation of the singularity of water quality, traditional Physiochemical and biochemical method.
The water quality characteristic of trade effluent
Trade effluent, especially the waste water of high density, high saliferous, high difficult degradation, water-quality constituents complexity, organic content is high, COD (chemical oxygen demand (COD)) generally more than 10000mg/L, even up to several ten thousand to hundreds of thousands of milligrams per liter, containing hazardous and noxious substances, saltiness is also high, has strong acid and strong base, can not directly carry out biochemical treatment.
Trade effluent is commonly used treatment process
For trade effluent, conventional processing mode is divided into two kinds: the first, physico-chemical process+biochemical process; The second, physico-chemical process+biochemical process+advanced treatment.The latter is used in situation that effluent quality has relatively high expectations, but two kinds of methods all need to, before waste water enters biochemical system, first be carried out physico-chemical pretreatment, reduce COD load in water, remove harmful toxic matter, to improve the biochemical effect of waste water.
The problem that conventional physico-chemical process exists
Conventional physico-chemical process comprises at present: the conventional arts such as Fenton, micro-electrolysis, electrocatalysis, microwave catalysis, ozone catalytic, Chlorine Dioxide Oxidation.These technological investments are large, processing cost is high, treatment effect is very limited, impact resistance is poor.Especially in the time that in waste water, COD concentration is higher than 20000mg/l, traditional physico-chemical process need add a large amount of oxygenants, cause processing cost high, and COD clearance is only 10-30%, also can introduce novel substance, causes secondary pollution.
The impact of conventional physico-chemical process existing problems on biochemical section
Tradition physico-chemical process COD clearance is low, not only can cause follow-up biochemical system influent load too high, very huge (common employing multistage anaerobic, the aerobic system series connection) that biochemical system is built, increase investment cost, but also can cause biochemical system fluctuation of service, final outflow water water quality is difficult to reach emission standard.
The limitation that the conventional embrane method of water treatment exists
The conventional embrane method of water treatment requires highly to influent quality, and invests hugely, and the rate of recovery is lower, and the concentrated solution producing is more difficult, and leading portion biochemical system thoroughly can not cause the pollution of the required membrane module of advanced treatment to Pollutant Treatment, affect treatment effect.
To sum up, adopt traditional materialization+biochemical technology to process the waste water of trade effluent, especially high density, high saliferous, high difficult degradation, not only invest hugely, processing cost is high, and treatment effect is very limited.
