Abstract

The invention discloses a composite sulfur-based porous filler. The filler is composed of one or more of a denitrification filler, a synchronous denitrification and dephosphorization filler, an alkalitype denitrification filler and an alkali type synchronous denitrification and dephosphorization filler. The denitrification filler comprises the following main components in percentage by weight: 10-15% of a polysulfide mixture, 75% of a sulfur preparation, 5-8% of a mixed foaming material and 5-7% of a binder. The device has the characteristics of high denitrification efficiency, low operationcost, low material loss, long filler replacement period, simple structure and the like.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a composite sulfur-based porous filler. Background technique [0002] With the promulgation of local standards in various provinces and cities across the country, such as the local standards of Beijing and Tianjin and the recently promulgated new policy of the main water pollution discharge standard (DB33 / 2169-2018) for urban sewage treatment plants in Zhejiang Province, the sewage treatment plants are required to meet Quasi-surface category IV and V, in which the total nitrogen TN≤10mg / L, and because Kunming enters Dianchi Lake, the total nitrogen TN≤5mg / L of the sewage plant is required. With the requirements of environmental governance, the discharge standard of total nitrogen will be more and more The more stringent it is, the development of deep denitrification technology with reliable application technology, low operating cost and high cost performance is an inevita...
