Embodiment 1

[0022] The application vertical flow bioretention system of the present embodiment removes the method for acetaminophen, comprises the following steps:

[0023] Such as figure 1 As shown, the reactor is a vertical flow bioretention system, the diameter of the reactor is 25cm, and the height is 50cm. The vertical flow bioretention system includes a pretreatment layer 1, a biological purification layer 2 and a deep treatment layer 3 from top to bottom. The pretreatment layer is a river sand filling layer, the river sand particle size is 1-2cm, and the thickness of the river sand filling layer is 8cm. The biological purification layer is a volcanic rock filling layer, and the volcanic rock particle size is 1-2cm. The thickness of the layer is 20cm, the deep treatment layer is a volcanic rock filling layer, the particle size of the volcanic rock is 3-5cm, and the thickness of the volcanic rock filling layer is 12cm. The water enters from the pretreatment layer, and the water exit...

Abstract

The invention discloses a method of removing paracetamol by applying a vertical-current biological retaining system. According to the method disclosed by the invention, a modularized biological retaining system can be introduced to purify a water pollutant containing paracetamol, so that not only can requirements of biological water treatment technical development of synchronous detoxification denitrification be achieved, but also pollution of the paracetamol can be quickly degraded. The method has the advantages such as simplicity in operation, certain pollution load resistance, and the like, and is very suitable for a water treatment process of wide areas such as municipal sewage and agricultural sewage.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for removing acetaminophen by using a vertical flow biological retention system. Background technique: [0002] The problem of water environmental pollution has attracted increasing attention from the public, and the problem of pollution caused by the coexistence of new toxic pollutants and ammonia nitrogen has begun to appear. These two types of water pollutants will seriously affect and threaten my country's water environment security. The harm of ammonia nitrogen pollution has a long history and comes from the degradation of various nitrogen-containing pollutants. Generally, the conversion time of ammonia nitrogen is long, and it often gradually accumulates in the polluted water body that is already anoxic, becoming a pollutant that accounts for 60% of the total nitrogen in the water body. Ammonia nitrogen is a nutrient in water bodies, ...
