过氧化钙对黑臭水净化效果的研究
Study on the Purification Effect of Calcium Peroxide on Black and Ordorous Waster Water
摘要
Abstract
The purification effect of calcium peroxide on black and odorous waster water,the dissolved ox-ygen,pH and ammonia nitrogen in black and odorous waster water was studied under different condi-tions.Studies show that calcium peroxide dosing quantity and its handling efficiency on black smelly wa-ter increase before they tend to be balanced.Unden optimal dosing quantity of 1.2 g/L,ammonia nitro-gen removal efficiency is 48.94%,dissolved oxygen increases to 32.1 mg/L.The removal efficiency of ammonia nitrogen increases with standing time.When the standing time was 2 days,the removal efficien-cy reaches the maximum of 67.03%.In addition,the initial pH has a greater effect on the removal effi-ciency of ammonia nitrogen.The removal efficiency of ammonia nitrogen is the highest when the initial pH is 10,and the ammonia nitrogen removal efficiency is the lowest when the initial pH is 2.The results can be applied to engineering practice.关键词
