Efficient denitrification unit based on sulfur autotrophic technology and filling distributing method thereof

Abstract

The embodiment of the invention discloses an efficient denitrification unit based on a sulfur autotrophic technology. The unit comprises a unit body, the unit body is a hollow cuboid, and the longestside of the unit body is arranged vertically; a water feeding pipe and a sludge discharging pipe are arranged on the lower portion of the side face of the unit body, and a water outlet pipe is arranged on the upper portion of the side face of the unit body, wherein multiple suspending ropes are arranged on the inner side of the top face of the unit body, each suspending rope is provided with multiple filling hollow spheres, and the filling hollow spheres are used for filling of sulfur-containing solid filling used for denitrification. The unit is used for solving the problems that in the priorart, since filling is directly added, overhauling time is wasted, filling distributing is not uniform, the filling cannot make sufficient contact with treated water, and sulfur autotrophic denitrification efficiency is low. The embodiment of the invention further provides a filling distributing method of the efficient denitrification unit.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, in particular to a high-efficiency denitrification unit based on sulfur autotrophy technology and a cloth distribution method thereof. Background technique [0002] The annual domestic sewage production in our country is as high as tens of billions of tons. If the treatment is not up to standard and discharged into the external environment, the excessive nutrient element nitrogen will destroy the water ecological environment, and even affect the health of humans and animals. my country's "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB 18918-2002) stipulates that total nitrogen should be less than 15mg L -1 It meets the Tier 1 A emission standard. Sensitive water bodies such as the Beijing-Tianjin region often have stricter requirements on inflow water quality than Class A discharge standards. Therefore, controlling the total nitrogen content in discharge...
