Description

Technical Field

[0001] The utility model relates to the technical field of sludge odor treatment, in particular to a high-concentration sludge deodorizing device. Background Art

[0002] Sludge is a solid sediment produced during the treatment of water and sewage. Sludge usually has the following characteristics: Complex composition: It contains a variety of components such as organic matter, inorganic matter, microorganisms, heavy metals, etc. Organic matter may include bacteria, algae, protein, carbohydrates, etc.; inorganic matter includes silt, minerals, etc.; heavy metals may come from industrial wastewater. High water content: Generally between 75% and 99%, which makes it bulky and difficult to transport and handle. Odor: Due to the decomposition products and microorganisms of organic matter, it often emits an unpleasant odor. Potential pollution: If not properly treated and disposed of, the harmful substances in it may pose a threat to the environment and human health, such as contaminating soil and groundwater. Common methods for the treatment and disposal of sludge include: Concentration and dehydration: Reduce the water content of sludge and reduce its volume. Digestion: Reduce the content of organic matter through anaerobic or aerobic digestion. Incineration: Burn the sludge at high temperature to achieve reduction and harmlessness. Land use: In compliance with relevant standards, the treated sludge is used for agriculture or gardening.

[0003] Sludge deodorization equipment usually consists of the following main structural parts: Intake system: used to collect sludge gas containing odor, usually including pipes, ventilators and air inlets. The ventilator provides power to draw the odor into the deodorization device. Filter unit: may include primary filter and medium filter, used to remove large particle impurities and some dust in the gas, and protect the subsequent processing components. Chemical scrubber: contains chemical scrubbing liquid, such as acid and alkali solution. When the gas passes through the scrubber, some water-soluble pollutants and acidic or alkaline gases react chemically with the scrubbing liquid and are removed. Biological treatment unit: common ones are biofilter or biotrickling filter. Filled with specific microbial carriers, microorganisms grow and reproduce in a suitable environment, and decompose and transform the organic components in the odor as nutrients. Activated carbon adsorption tower: filled with activated carbon, using the adsorption properties of activated carbon to adsorb the remaining odor molecules and trace pollutants, and further purify the gas. Exhaust system: composed of exhaust pipe and exhaust fan, discharge the treated qualified gas into the atmosphere. Control system: includes sensors, controllers and actuators. The sensors monitor the concentration, temperature, humidity and other parameters of the intake air, and the controller adjusts the operating parameters of the device according to these parameters, such as the fan speed, washing liquid flow, etc., to ensure the efficient and stable operation of the device.
