Embodiment Construction

[0039] see figure 1 , the present invention proposes a kind of equipment used in the treatment method of deep purification and reuse of refractory wastewater with small amount of water, the equipment includes a pre-filter 1, a water storage tank (not shown in the figure), a spray fluidized bed reaction tower 3 , a circulation pump 4, an ozone (O 3 ) generator 5, a microwave catalytic reactor 6, a UV photochemical reactor 7, and a clarification filter 8.

[0040] Waste water to be treated enters from the top of the pre-filter 1 , and the bottom of the pre-filter 1 is connected to the water storage tank, and the water storage tank is connected to the spouted fluidized bed reaction tower 3 . The pre-filtered waste water flows into the spouted fluidized bed reaction tower 3 after passing through the water storage tank.

[0041] The spouted fluidized bed reaction tower 3 includes a vertical section 32 with a cone in the lower part and an enlarged section 34 in the upper part.

Abstract

The invention relates to a treatment method for small water quantity refractory wastewater deep purifying and utilizing. The method comprises the following steps: step one, pre-filtrating wastewater is performed firstly; step two, the pH value of the wastewater is adjusted to 3-5 to ensure the wastewater to present subacidity; step three, the wastewater flows into a spout-fluid bed reaction tower, the wastewater is processed through a micro-electrolysis method, and micro-electrolysis composite functional material is utilized in the micro-electrolysis method; step four, the wastewater is processed through a photo-assisted fenton catalytic oxidation method; step five, the pH value of the wastewater is adjusted to 6.8-7.8, and then the wastewater is processed through strengthen flocculation method; step six, the wastewater flows to a microwave catalysis reactor, and is processed through a microwave catalytic oxidation method; step seven, the wastewater flows into a UV photochemical reactor, and is processed through the UV photocatalysis; step eight, the wastewater flows into a gravitation filter, and the wastewater can be clarified to meet the requirement of the reuse water quality. The invention also provides equipment for performing the treatment method.

Description

technical field [0001] The invention relates to a treatment method for purification and reuse of wastewater and equipment for implementing the method, in particular to a method for purification and reuse of refractory wastewater and equipment for implementing the method. Background technique [0002] Industry is the pillar industry of the national economy. While the development of industry brings wealth to the country and people, it also brings problems of environmental pollution and resource shortage. Big problem ahead. Among them, a large amount of refractory wastewater produced in the process of industrial production pollutes the environment, and the refractory wastewater cannot be reused, which also exacerbates the shortage of water resources. [0003] Refractory wastewater traditionally refers to wastewater that is difficult to treat with conventional physical-chemical-biochemical methods, specifically refers to printing and dyeing, printing, dye production wastewater ...
