Problems solved by technology

At present, most of the agents used in chemical precipitation are sodium hydroxide and calcium hydroxide. However, although the single use of sodium hydroxide is better for wastewater treatment, the cost is too high and it is not suitable for batch use; and the single use of hydrogen Although the cost of calcium oxide is not high, waste water treatment will cause a large amount of sludge, resulting in difficulties in subsequent treatment, increased storage and transportation costs, etc., and its overall cost cannot be reduced

Abstract

The invention relates to the field of wastewater treatment and provides a circuit board wastewater treating agent and preparation and using methods thereof. The circuit board wastewater treating agentcontains the following components: 75-85% of calcium hydroxide, 5-15% of sodium hydroxide, 2-8% of aluminum sulfate, 1-5% of diatomite and 1-5% of activated carbon. Compared with generally adopted sodium hydroxide or calcium hydroxide added for chemical sedimentation of circuit board wastewater, the circuit board wastewater treating agent has the advantages of simplicity in material preparation,low treatment cost and obvious using effect.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and relates to a circuit board wastewater treatment agent, in particular to a circuit board wastewater treatment agent and its preparation and use methods. Background technique [0002] The composition of the wastewater produced in the production of circuit boards is very complex. In addition to the large amount of organic pollutants in the water, the wastewater also contains a large amount of heavy metals. The commonly used methods for treating circuit board wastewater include chemical methods, biological methods, physicochemical methods, and electrochemical methods. . Among them, the chemical method is the most commonly used method to treat circuit board wastewater. [0003] The chemical method relies on redox reaction or neutralization precipitation reaction to convert toxic and harmful substances into non-toxic and harmless substances, or directly removes heavy metals from wastewater by p...
