Problems solved by technology

However, there are two disadvantages: one is that a large amount of additional reagents needs to be added, which increases the operating cost; the other is that a large amount of iron sludge is generated, and solid-liquid separation is difficult, so a large-scale sludge treatment process needs to be invested in the follow-up

Embodiment Construction

[0009] experimental method

[0010] ① Use a lift pump to lift 200L of test wastewater to the original water tank;

[0011] ② Use 40% industrial grade sulfuric acid to adjust the pH of the above wastewater to 4;

[0012] ③Add about 1kg of polymetallic catalyst to the synergistic catalytic oxidation reactor, start the circulation pump, and adjust the flow rate to 200L / h.

[0013] ④Start the raw water pump, adjust the water inlet flow rate to 700ml / min, and start continuous water inlet;

[0014] ⑤ Start the dosing pump and add 30% H to the catalytic oxidation reactor 2 o 2 Agent, the catalytic oxidation reaction starts;

[0015] ⑥After being treated in the catalytic oxidation reactor, the effluent from the upper layer flows to the effluent tank by itself, and the catalyst flows in the reactor and does not flow out with the water;

[0016] ⑦ Collect treated water samples 2-3 hours after the start of the test. Then, adopt the batch test method, add 30% NaOH while stirring, ad...

Abstract

The invention discloses a multi-metal surface crystallization concerted catalysis oxidation reactor. The multi-metal surface crystallization concerted catalysis oxidation reactor comprises a catalytic oxidation reactor, wherein a three-phase separator, a fluidized crystallization area and a circulation water distribution area are arranged in the reactor. The multi-metal surface crystallization concerted catalysis oxidation reactor is based on improvement of a traditional oxidization method, manganese, magnesium, iron and aluminum alloy is used as a catalyst, and oxidizing reaction of H2O2 is catalyzed through the synergistic effect of multiple kinds of metal. The dosage of ferrous ions can be greatly reduced, pH range required by reaction is widened, operation cost is reduced, and sludge yield is reduced.

Description

technical field [0001] The invention relates to a polymetallic surface crystallization synergistic catalytic oxidation reactor. Background technique [0002] Fenton oxidation, as an advanced oxidation technology for sewage treatment, uses OH radicals to deeply oxidize organic matter in wastewater. It is considered to be the most effective and simple advanced oxidation method, with the advantages of high efficiency and rapid response. It is generally used to treat refractory organic wastewater. The traditional Fenton oxidation method has the disadvantages of requiring more chemicals, higher operating costs, and a large amount of sludge generated. At present, the traditional Fenton technology has been improved, and the electrolytic oxidation Fenton method, electrolytic reduction Fenton method, and photocatalytic oxidation method have appeared. Catalytic Fenton method, etc. The degradation of the common Fenton method mainly includes the oxidation and coagulation of organic ma...
