Problems solved by technology

[0002] In the existing sludge dehydration workshop, nitrogen is easy to lose during the process of sludge accumulation, and the loss is mainly through the conversion of ammonium nitrogen into ammonia volatilization, a small amount of loss with the aqueous solution, and nitrogen oxidation caused by nitrification or denitrification. emissions
This not only reduces the nutrients of the sludge, but also brings environmental problems such as stench and acid rain

Embodiment 1

[0016] This embodiment provides a biological deodorization method in a sludge dehydration workshop, specifically:

[0017] Add chemical nitrogen retaining agent to sludge, said chemical nitrogen retaining agent includes sludge activated carbon, Mg(OH) 2 、H 3 PO 4 and H 2 O, by mass ratio sludge activated carbon: Mg(OH) 2 :H 3 PO 4 :H 2 O=18:7:15:60.

Embodiment 2

[0019] In this example, the performance of the method described in Example 1 is further verified through experiments.

Abstract

The invention discloses a biological deodorization method used in a sludge dehydration workshop. The method specifically comprises the following steps: putting a chemical nitrogen retaining agent intosludge, wherein the chemical nitrogen retaining agent comprises sludge activated carbon, Mg(OH)2, H3PO4 and H2O; and the mass ratio of the sludge activated carbon to the Mg(OH)2 to the H3PO4 to the H2O is 18:7:15:60. By adopting the method disclosed by the invention, nitrogen loss in the sludge piling process can be effectively prevented, and thus a deodorization effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of sludge deodorization, in particular to a biological deodorization method for a sludge dehydration workshop. Background technique [0002] In the existing sludge dehydration workshop, nitrogen is easy to lose during the process of sludge accumulation, and the loss is mainly through the conversion of ammonium nitrogen into ammonia volatilization, a small amount of loss with the aqueous solution, and nitrogen oxidation caused by nitrification or denitrification. emissions. This not only reduces the nutrients of the sludge, but also brings environmental problems such as stench and acid rain. Therefore, controlling nitrogen loss during sludge accumulation has always been a research hotspot of scholars at home and abroad. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a biological deodorization method for a sludge dehydration workshop, w...
