在良工阀门中哪些阀门用于废水和污水处理?我国水污染的不断加剧,使污水处理与再生产业受到重视。在污水处理管道系统中,阀门起着非常重要的作用。污水处理广泛应用于建筑、农业、交通、能源、石化、、城市景观、医疗、餐饮等领域,越来越多地走进普通百姓的日常生活。
Which of the Lianggong valves are used for wastewater and sewage treatment? With the continuous aggravation of water pollution in China, the sewage treatment and recycling industry has been attached great importance. In the sewage treatment pipeline system, valves play a very important role. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and more and more people are entering the daily life.
现代污水处理技术按处理程度可分为一级处理、二级处理和三级处理。一般来说,污水处理的程度是根据水质和被处理水的去向来确定的。在良工阀门中每个级别使用的阀门也不同。主要去除污水中的悬浮固体污染物,大部分物理处理方法只能完成初级处理的要求。污水经一级处理后,BOD一般可去除30%左右,达不到排放标准。一级处理属于二级处理的预处理。所用阀门及其管道附件:刀闸阀、三偏心蝶阀、过滤器等
Modern sewage treatment technology can be divided into primary treatment, secondary treatment and tertiary treatment according to the treatment degree. Generally speaking, the degree of sewage treatment is determined according to the water quality and the destination of the treated water. The valves used in each level of Lianggong valves are also different. It mainly removes suspended solid pollutants in sewage, and most physical treatment methods can only meet the requirements of primary treatment. After primary treatment, BOD can generally be removed by about 30%, which can not meet the discharge standard. The primary treatment belongs to the pretreatment of the secondary treatment. Valves and pipe accessories used: knife gate valve, three eccentric butterfly valve, filter, etc
主要去除污水中的胶体和溶解性有机污染物(BOD、COD物质),去除率可达90%以上,使有机污染物达到排放标准,悬浮物去除率可达95%,出水效果好。在良工阀门中所用阀门有软密封蝶阀、闸阀、球阀、止回阀等进一步处理难降解有机物、氮磷等可导致水体富营养化的可溶性无机物。主要方法有生物反硝化除磷、混凝沉淀、砂滤、活性炭吸附、离子交换和电渗析。使用的阀门有对夹蝶阀、闸阀、球阀、止回阀、橡胶软接头等。
It mainly removes colloid and dissolved organic pollutants (BOD and COD substances) in the sewage, with a removal rate of more than 90%, so that the organic pollutants can meet the discharge standard, and the removal rate of suspended solids can reach 95%. The effluent effect is good. The valves used in Lianggong valve include soft sealing butterfly valve, gate valve, ball valve, check valve, etc. to further treat the refractory organic matter, nitrogen and phosphorus and other soluble inorganic matter that can lead to eutrophication of water body. The main methods are biological denitrification phosphorus removal, coagulation sedimentation, sand filtration, activated carbon adsorption, ion exchange and electrodialysis. The valves used include wafer butterfly valve, gate valve, ball valve, check valve, rubber soft joint, etc.
