餐厨垃圾水解酸化液应用于污水厂的研究

Feasibility Study on Application of Kitchen Waste Hydrolyzed Acidifi cation Solution in Domestic Sewage Treatment Plant

本文模拟餐厨垃圾水解酸化液纳入光明水质净化厂的实验,研究了餐厨垃圾水解酸化液纳入污水处理厂作为碳源补充的可行性。结果表明:餐厨垃圾水解酸化液可补充污水处理过程微生物新陈代谢所需的碳源和无机盐,加入餐厨垃圾水解酸化液能提升总氮去除率,从83%提升至91%,改善出水水质的同时,为污水处理厂节省碳源投加量,降低生产运营成本。

This article simulates the experiment of incorporating the hydrolyzed and acidified solution of kitchen waste into Guangming water purification plant,and studies the feasibility of incorporating the hydrolyzed and acidified solution of kitchen waste into the sewage treatment plant as a carbon source supplement.The results show that the kitchen waste hydrolyzed and acidified solution can supplement the carbon sources and inorganic salts required for microbial metabolism in the sewage treatment process,and the addition of the kitchen waste hydrolyzed and acidified solution can increase the total nitrogen removal rate from 83%to 91%,and improve the effluent quality.At the same time,it saves the amount of carbon source added for the sewage treatment plant and reduces the production and operation cost.
