Denitrification earthenware brick

Abstract

The invention discloses a denitrification ceramic tile. The brick comprises a brick body, wherein the brick body comprises a bottom plate; a connecting plate is arranged on the upper surface of the bottom plate; two groups of brick feet are arranged on two sides of the bottom plate; two convex feet are arranged between the two groups of brick feet; the brick body is composed of sludge, quick lime,cement, ceramic blocks and sea salt. The sludge, the quick lime, the cement, the ceramic blocks and the sea salt are mixed and stirred; and the brick body is formed by a mold. According to the technical scheme, ammonia nitrogen in a river channel water body can be effectively removed, the purpose of water quality purification is achieved, the problem of sludge dumping generated after river channel dredging can be solved to a certain extent, sludge is turned into wealth and comprehensively utilized, and the method is a long-acting, environment-friendly and ecological water quality treatment scheme.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a denitrification pottery brick. Background technique [0002] The current water pollution is becoming more and more serious, and the sewage often cannot meet the discharge standards after secondary treatment. Whether it is the upgrading of old sewage plants or the advanced treatment of new water plants, fast and efficient new technologies and new products are urgently needed. [0003] Chinese patent literature discloses a device for treating ammonia nitrogen in wastewater by using microbial methods [authorized announcement number: CN 205472971 U], in which a sewage inlet and a clear water overflow are respectively formed on both sides of the tank, and an aeration device is installed at the bottom of the tank. There is a gap between the top plate and the bottom plate of the tank, and there is a layer of sea sand with live bacteria attached between two adjacent baffles, wh...

AI Technical Summary

Problems solved by technology

[0004] 1. Only part of the ammonia nitrogen can be removed to a limited extent, and the biological transformation is carried out non-physically, and the biological transformation speed is slow;

[0005] 2. Using biological solutions, biological bacteria are consumables, which need to be replenished frequently, and the input cost is relatively high;

[0006] 3. It only partially solves the ammonia nitrogen, but cannot solve the continuous production of new ammonia nitrogen by a large amount of sludge organic matter in the water body
