Description
技术领域technical field
本实用新型涉及一种污泥的处理装置，尤其是涉及一种污泥干化处理装置。The utility model relates to a sludge treatment device, in particular to a sludge drying treatment device.
背景技术Background technique
城市污水厂的污泥是指处理污水所产生的固态、半固态及液态的废弃物，含有大量的有机物、重金属以及致病菌和病原菌等，不加处理任意排放，会对环境造成严重的污染。对污泥处理总的要求是稳定化、无害化和减量化。随着污水处理设施的普及、处理率的提高和处理程度的深化，污水厂的污泥产生量将有较大的增长，由此引起的二次污染问题已不容忽视。因此如何合理地处理、处置污泥，已成为城市污水厂和相关部门必需引起重视的问题。Sludge from urban sewage plants refers to the solid, semi-solid and liquid wastes produced by sewage treatment. It contains a large amount of organic matter, heavy metals, pathogenic bacteria and pathogenic bacteria, etc. If it is discharged without treatment, it will cause serious pollution to the environment. . The general requirements for sludge treatment are stabilization, harmlessness and reduction. With the popularization of sewage treatment facilities, the improvement of treatment rate and the deepening of treatment degree, the amount of sludge produced in sewage plants will increase greatly, and the secondary pollution caused by this can no longer be ignored. Therefore, how to treat and dispose of sludge reasonably has become a problem that must be paid attention to by urban sewage plants and related departments.
国内外污泥处理与处置的方法很多，一般采用浓缩、消化、脱水、干化、有效利用(多为农用)、填埋及焚烧等，或用其中几个方法组合处置。应该说，对污水厂污泥的处理和处置，我们与先进国家相比，差距较大。近几年，由于有脱磷脱氮要求，演变出不少污水生物处理工艺，而对污泥处理和处置，设计中一般只提将脱水污泥外运和综合利用，未计算其投资和经常费用，这势必会造成二次污染。处理厂建得越多，污泥的二次污染亦越广泛。未经稳定处理的污泥，因有机物含量高，极易腐败并产生恶臭，尤其是初沉淀池的污泥，含有大量病菌、寄生虫卵及病毒，易造成传染病的传播。There are many methods for sludge treatment and disposal at home and abroad, generally using concentration, digestion, dehydration, drying, effective utilization (mostly for agricultural use), landfill and incineration, etc., or a combination of several methods. It should be said that compared with advanced countries, we have a large gap in the treatment and disposal of sludge from sewage plants. In recent years, due to the requirements of dephosphorization and nitrogen removal, many sewage biological treatment processes have evolved. For sludge treatment and disposal, the design generally only mentions the export and comprehensive utilization of dewatered sludge, without calculating its investment and frequent costs. cost, which will inevitably cause secondary pollution. The more treatment plants are built, the more extensive the secondary pollution of sludge will be. Sludge that has not been stabilized is prone to corruption and odor due to its high content of organic matter, especially the sludge in the primary sedimentation tank, which contains a large number of germs, parasite eggs and viruses, which can easily cause the spread of infectious diseases.

The drying time is short, and the cationic polyacrylamide will produce a compressed electric double layer, which will make the suspended particles in the wastewater lose stability, and the colloidal particles will coagulate with each other to make the particles Increase to form flocs and alum flowers. After the floc grows to a certain volume, it will separate from the water phase and settle under the action of gravity, thereby removing a large amount of suspended solids in the wastewater, thereby greatly improving the effect of sludge dewatering. At the same time, it can also reduce the moisture content after dehydration and improve work efficiency. The utility model combines multiple dehydration programs, and the dehydration effect is good, and the water content can be reduced to about 25%.
