Description
Technical Field
The invention relates to the technical field of sludge treatment devices, in particular to circulating ozone multi-element catalytic oxidation sludge treatment equipment.
Background
With the continuous development of urban process and production activities, wastewater treatment process has become an extremely important part of the environmental protection field. In general, wastewater treatment produces a large amount of sludge, and the environmental and ecological effects of the waste are serious.
At present, an ozone oxidation sludge reduction technology has become a technology means for effectively reducing the amount of sludge generated in the wastewater treatment process, and the ozone oxidation sludge reduction technology is to add ozone gas to oxidatively decompose organic substances in the sludge, so that the generation amount of the sludge is reduced. The ozone oxidation can break double bonds or triple bonds in molecules to degrade the molecules into substances such as organic acid, carbon dioxide and the like, so that the reduction purpose is realized, and compared with the traditional chemical hormone treatment and biological treatment, the ozone oxidation sludge reduction technology has the following advantages: 1. the ozone oxidation reaction speed is high, the usage amount of the reactant is small, and the treatment efficiency is high; 2. the ozone oxidation can directly oxidize and decompose organic substances in the sludge, so that secondary pollution is avoided; 3. the ozone oxidation reaction time is short, and the treatment period can be greatly shortened; 4. ozone oxidation can be applied to various types of organic wastewater, and the treatment effect is stable. Therefore, the ozone oxidation sludge reduction technology has been widely applied to various types of wastewater treatment processes, effectively reduces the generation amount of sludge, and better protects the environment and ecology.
The general technology adopted at present is as follows: 1. biological treatment technology: the organic matters in the sludge are decomposed into inorganic matters by utilizing the metabolism of microorganisms, so that the sludge amount is reduced.
2. Heat treatment technology: the sludge is treated at high temperature, so that the volume and the weight of the sludge are reduced, and simultaneously, organic matters and pathogenic microorganisms in the sludge can be thoroughly destroyed.
3. Chemical treatment technology: organic matters in the sludge are decomposed into gas and liquid by using chemical agents, so that sludge reduction is realized.
4. Mechanical treatment technology: the sludge is compressed, squeezed, concentrated or dried by using manpower or equipment, thereby reducing the volume and weight thereof.
5. Microwave treatment technology: the high-frequency microwave energy is conducted into the sludge particles to heat the sludge particles rapidly, so that sludge drying and reduction are realized.
6. Other techniques: such as an oxidizing agent method, an ultraviolet treatment method, etc., can also be used for sludge reduction.
The above-mentioned techniques have the following general drawbacks: 1. the biological treatment is to build excellent microbial community to accelerate the decomposition and oxidative degradation of sludge in anaerobic or aerobic environment, so as to achieve the purpose of decrement. However, the biological treatment technology needs a large amount of input microorganisms and maintains a constant ecological environment, is also easily influenced by factors such as unstable water quality of inflow water and process operation, and has the defects of high cost and great technical difficulty.
2. The physicochemical treatment mainly separates solid particles in the sludge by methods such as pressure filtration, centrifugation, filtration and the like, reduces the volume of the sludge, but can not realize complete degradation of organic matters, and also requires a large amount of energy and equipment investment, so the cost of the sludge is higher. The incineration treatment is to burn the sludge at high temperature, so that organic matters can be degraded into CO2 and water, the volume of the sludge and secreted pollutants are effectively reduced, but a large amount of energy is required in the process, and harmful gases such as nitrogen oxides, dioxins and the like are easy to generate, so that the environmental impact is large.
3. The desiccation treatment evaporates the water in the sludge by means of evaporation, aeration and the like, so that the volume of the sludge is reduced, but the desiccated sludge becomes hard and is difficult to further treat, and a large amount of sites are required to be occupied for storage.
4. The microwave auxiliary treatment is to increase the degradation rate of sludge by utilizing the heating effect of microwaves, reduce the treatment time and effectively reduce the sludge, but needs a large amount of energy and specialized equipment, and has high cost.
