Description
Technical Field
The utility model relates to a waste water suspended solid sludge treatment device that dyestuff manufacture produced belongs to waste water treatment technical field.
Background
In the production of cationic dyes, disperse dyes, liquid cationic dyes, liquid direct dyes, liquid paper dyes, liquid ink-jet dyes, high-grade disperse dyes and the like, the produced wastewater is about 20m3And d, according to the relevant requirements of environmental protection, the effluent meets the standard of wastewater discharge town sewer water quality (DB31/445 + 2009), and the water quality of the inlet and outlet water is shown in the following table:
the dye production wastewater contains substances such as acid, alkali, salt, halogen, hydrocarbon, nitro, amine, dye and intermediate thereof; some also contain highly toxic benzidine, pyridine, cyanogen, phenol, and heavy metals such as mercury, cadmium, chromium, etc. The waste water has complex components, toxicity and difficult treatment. In recent years, as the waste water of dye production increases, the harm is more serious, and some factories and some products have to stop production. Many countries are exploring new methods for dye wastewater treatment. Some treatment methods are preliminarily mastered by Chinese through experimental studies.
The quality of the wastewater generated in dye production is complex, and a proper treatment method is selected according to the characteristics of the wastewater and the discharge requirement of the wastewater. Removing solid impurities and inorganic substances by coagulation and filtration; the decoloring can generally adopt a process flow consisting of a coagulation method and an adsorption method; removing toxic substances or organic substances by mainly adopting a chemical oxidation method, a biological method, a reverse osmosis method and the like; for removing heavy metals, ion exchange method and the like can be used. The common method for treating dye wastewater is as follows:
a chemical coagulation method: the low-concentration dye waste water containing acid, alkali, salt and organic matter is first homogenized and precipitated, neutralized with proper amount of alkali or acid and flocculated and precipitated with coagulant. The coagulant can be aluminum sulfate, ferrous sulfate, polyaluminum chloride, polyacrylamide, etc. The treatment effect of the dye wastewater flocculation precipitation depends on the selection and the dosage of the coagulant and the coagulant aid, the pH value of the wastewater and the hydraulic condition of coagulation. The chemical coagulation method can generally remove 70-90% of chroma and 50-80% of COD (chemical oxygen demand).
The biological method comprises the following steps: commonly used biological methods include an activated sludge method, a biofilm method, an oxidation pond method, an anaerobic biological method, and the like. The biological method can treat most of the dye wastewater. The waste water contains amines, phenols and the like, and has better effect by biological treatment. The acidic and alkaline waste water can be treated by neutralization and then by biological method; the azo dye and sulfur dye waste water can be reduced and oxidized to reduce the toxicity and then treated by a biological method.
An adsorption method: the common adsorbents include activated carbon, activated diatomite, activated coal, activated clay, lignite, polymeric adsorbents and the like. Granular activated carbon or activated coal is generally used. The adsorption capacity of each adsorbent to different types of dye production wastewater is different, namely the adsorbents have selectivity. The adsorption method can remove the substances which are difficult to decompose in the wastewater; the waste water which is not suitable for being treated by the biological method or the waste water which does not reach the discharge standard after being treated by the biological method can be treated by an adsorption method. If the wastewater contains a high concentration of organic substances, the treatment by adsorption with activated carbon is uneconomical.
An oxidation method: the method destroys the organic matters in the wastewater through strong oxidation, thereby achieving the purposes of more thoroughly decoloring, detoxifying, deodorizing and deodorizing. It is one of the main subjects of the current dye wastewater treatment research. As the oxidation method, there can be used ozone oxidation, chlorine-added oxidation, radiation oxidation, photo-oxidation, electrolytic oxidation, wet air oxidation, combustion, nitric acid air oxidation and the like. China has achieved certain achievements in ozone oxidation and photo-oxidation. Generally speaking, ozone has high decolorizing speed and good effect on hydrophilic dyes (such as direct dyes, acid dyes, basic dyes, reactive dyes and the like); has poor decolorizing and treating effects on hydrophobic dyes (such as vat dyes, naftidrofil dyes, oxidation dyes, sulfur dyes, disperse dyes and the like and coating materials) and has large using amount. When the chromium-containing dye wastewater is treated by ozone, hexavalent chromium ions are generated, and the toxicity is increased. Therefore, the ozone treatment of the dye wastewater has certain selectivity. The photooxidation method is to utilize light and oxidant to produce a strong oxidation effect together to make the pollutant in the waste water undergo the process of oxidative decomposition so as to basically remove COD and BOD (biochemical oxygen demand) from the waste water. Common oxidants used in the photo-oxidation method include ozone, chlorine, hypochlorous acid, air, hydrogen peroxide and the like; the light source is ultraviolet (but it is to be understood which particular wavelength is most effective for which dye). The method has the advantages of strong oxidation capability, no sludge generation, compact equipment and high power consumption.
In addition to the above-mentioned method, the ion exchange method, reverse osmosis method, extraction method, foam separation method and incineration method can be used for recovering material and making harmless treatment of waste water.
However, for wastewater treatment equipment, particularly for wastewater suspended matter sludge treatment equipment produced in dye manufacturing, because the factory production wastewater treatment process "production wastewater → regulating tank → acidification hydrolysis tank → contact oxidation tank → sedimentation tank → clean water tank → ozone oxidation system", AO is selected for process biochemistry, the load is calculated correctly, but the dye production wastewater generally contains substances such as acid, alkali, salt, halogen, hydrocarbon, nitro compound, amine, dye and intermediate thereof; some also contain highly toxic benzidine, pyridine, cyanogen, phenol, and heavy metals such as mercury, cadmium, chromium, etc. The waste water has complex components, toxicity, direct entering a biochemical system, direct influence on the biological activity of the biochemical system, reduction of the treatment efficiency of the biochemical system, high suspended matter of dye waste water and more sludge. Therefore, the conventional equipment has the defects of more cleaning frequency and large cleaning difficulty.
