Embodiment Construction

[0040] In order to make the above-mentioned features and advantages of the present invention more comprehensible, a number of embodiments will be described in detail below together with the accompanying drawings.

[0041] figure 1 A flow chart of a method for recycling and treating ammonia-containing wastewater according to an embodiment of the present invention is drawn. Please refer to figure 1 As shown, the recovery and treatment method of ammonia-containing wastewater includes the following steps. First, as shown in step S110, a first acidic solvent is added to the ammonia-containing wastewater to adjust the original alkaline ammonia-containing wastewater to slightly acidic (slightly acidic), that is, to adjust its pH value to be lower than 7, or even It is adjusted to be lower than 6.5, thus forming acidic wastewater. Next, as shown in step S120 , the acidic wastewater is separated into high-concentration wastewater and low-concentration wastewater by using the reverse...

Abstract

The invention provides an ammonia wastewater recycling method and an apparatus, wherein the recycling method comprises the procedures of adjusting ammonia wastewater into acidic wastewater; isolating high concentration wastewater from the acidic wastewater by using a reverse osmosis film; then, adding an alkaline solvent into the high concentration wastewater to obtain ammonia; and obtaining and recycling ammonium compounds by reaction between an acidic solvent and the ammonia. The invention also provides an ammonia wastewater recycling apparatus. The acidic wastewater is formed in a first pH value adjusting groove; then high concentration wastewater is isolated by using the reverse osmosis film; then the pH value of the high concentration wastewater is adjusted into alkaline in a second pH value adjusting groove to generate ammonia. Then, the ammonia reacts with the acidic solvent in a separating apparatus to obtain the ammonium compound. After that, the ammonium compound is recycled into a recycling groove.

Description

technical field [0001] The present invention relates to a recycling method and equipment for waste water, and in particular to a recycling method and equipment for ammonia-containing wastewater. Background technique [0002] With the increasingly severe climate change, the probability of floods and droughts around the world is gradually increasing, which makes it more and more difficult to effectively preserve and utilize clean water resources that are indispensable for human survival. More importantly, the rapid growth of the global population and the rapid development of industrial technology have led to increasingly serious environmental pollution by human beings, which has worsened the problem of water resource conservation and utilization. Therefore, how to effectively recycle the pollutants in industrial waste water so as to reduce the pollution of the pollutants to the environment has gradually become one of the urgent problems to be solved by governments around the w...
