Nylon slice process wastewater treatment device and its treatment method

Abstract

The invention relates to an ammonia nitrogen removal device for chinlon chips.The device comprises an anaerobic jar, wherein an overflow pipeline is arranged on the anaerobic jar, and an anaerobic sedimentation tank, an anoxic tank, a contact oxidation secondary sedimentation tank and a three-level peroxidatic reaction ternary sedimentation tank are arranged on the overflow pipeline in sequence.The device has the advantages that production process wastewater in a process wastewater pipeline and sanitary sewage in a sanitary sewer are collected in a centralized mode and homogenized through a water quality regulating reservoir, part of organic matter in wastewater is removed through the anaerobic jar, wastewater is made to pass through the anaerobic sedimentation tank, the anoxic tank, the contact oxidation secondary sedimentation tank and the three-level peroxidatic reaction ternary sedimentation tank in sequence through the overflow pipeline and then is collected through a middle pond, the content of CODcr in wastewater in the middle pond is 85-100 mg / l, the content of NH3-N is smaller than 0.1 mg / l, wastewater discharge standard is met, collection and utilization of wastewater are achieved, and environment pollution is reduced.The invention further discloses an ammonia nitrogen removal process for chinlon chips.

Description

technical field [0001] The invention relates to a wastewater treatment device for nylon slicing process and a treatment method thereof. Background technique [0002] At present, the existing nitrification and denitrification process A-O pool, A is the anoxic denitrification pool, which uses denitrifying bacteria to denitrify, and uses the water source to make the nitrate and nitrite in the reflux liquid denitrify and convert into nitrogen, from The overflow in the water is removed, while the O pool uses aerobic microbial degradation to fully decompose the remaining organic matter in the wastewater, and then uses the nitrification of the digestive bacteria to realize the nitrification reaction of ammonia nitrogen, and the mud and water are separated through the biochemical sufficient water to flow into the contact pool. The pool uses microorganisms to further process the residual ammonia nitrogen and organic matter. The effect of reducing ammonia nitrogen in contact with the ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a wastewater treatment device for nylon slicing process and its treatment method, which can effectively solve the problem that the effect of reducing ammonia nitrogen in the existing contact pool is not obvious and the waste gas is directly discharged into the atmosphere
