Composite catalyst for aid-containing wastewater treatment
A composite catalyst and wastewater treatment technology, which is applied in physical/chemical process catalysts, molecular sieve catalysts, water/sewage treatment, etc., can solve the problems of large changes in pollutant concentration, avoid the loss of active metals, and stabilize catalyst performance. The effect of widening the operating temperature

Examples
Embodiment 1
[0032] Preparation of Catalyst A:
[0033] 1) claim that 261g ruthenium chloride trihydrate is dissolved in 10L deionized water to form solution A;
[0034] 2) Weigh 1Kg of coconut shell activated carbon, place it in a muffle furnace at 100°C for high temperature activation for a period of time, and cool to room temperature to obtain activated carrier B;
[0035] 3) Add 500g of activated carrier B to 2L of solution A and soak for 5 hours, and filter to obtain catalyst precursor C;
[0036] 4) Precursor C was dried at 80° C. for 5 hours, and then calcined at 800° C. for 8 hours to obtain catalyst A. According to detection and analysis, the loading amount of ruthenium was 0.21 wt%.
Embodiment 2
[0038] Preparation of Catalyst B:
[0039] 1) Weigh 250g of manganese nitrate and dissolve it in 5L of deionized water, then add 150mL of 30% hydrogen peroxide, and react at 30°C for 1 hour to obtain reaction solution A;
[0040] 2) Add 1Kg ZSM-5 molecular sieve to the reaction solution A and soak for 5 hours, filter and dry to obtain catalyst precursor A;
[0041] 3) Dissolve 26g of cobalt chloride and 272g of zinc chloride in 5L of deionized water to obtain solution B, place precursor A in solution B and immerse for 5 hours to obtain catalytic precursor B;
[0042] 4) Dry the catalyst precursor B at 80°C for 3 hours, then put it into a muffle furnace, and calcinate it at 600°C for 8 hours to obtain catalyst B. After detection and analysis, the content of the catalyst active component Mn is 1.12wt %, the content of Co is 0.12wt%, and the content of zinc is 2.08wt%.
Embodiment 3
[0044] The catalyst A1 prepared in Example 1 is mixed with the catalyst B1 prepared in Example 1 in a mass ratio of 1:10 composite catalyst D1.
