Embodiment Construction

[0034] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, the spunlace circulating water treatment process of the present embodiment includes the following steps:

[0036] The first step: the waste water enters the mixing reaction tank through the flat belt filter, and the dosing device connected to the mixing reaction tank performs the dosing and mixing reaction;

[0037] Step 2: After the waste water is reacted in the mixing reaction tank, it enters the air flotation device, and the upper scum and bottom clean water are formed through the air flotation device, and the clean water at the bottom flows to the middle water tank;

[0038] Step 3: The intermediate water tank sends water to the multi-functional filter through the intermediate feed water pump;

[0039] Step 4: The water filtered by the multifunctional filter enters the first stage bag filter;

Abstract

The invention relates to a spunlace circulating water treatment process. The spunlace circulating water treatment process comprises the following steps that wastewater enters a mixing reaction tank through a flat belt filter and undergoes a chemical-dosing mixing reaction through a chemical dosing device connected to the mixing reaction tank; wastewater after being reacted in the mixing reaction tank enters an air floatation device to form upper scum and bottom clean water through the air floatation device, and the clean water at the bottom layer flows to an intermediate water tank; water is pumped into a multifunctional filter through an intermediate feed pump on the intermediate water tank; water filtered by the multifunctional filter enters a first-level cloth bag filter; water filtered by the first-level cloth bag filter enters a head water tank to be stored and clear water in the head water tank is pumped into a second-level cloth bag filter through a booster pump; water filtered by the second-level cloth bag filter is pumped into a spunlace machine through a high pressure pump to carry out spunlace production; wastewater generated in the spunlace production of the spunlace machine flows to a negative pressure suction tank; water in the negative pressure suction tank is pumped out through a suction pump and conveyed to the flat belt filter to be recycled. The spunlace circulating water treatment process is good in water treatment effect and the quality of the outlet water meets the requirements.

Description

technical field [0001] The invention relates to the technical field of circulating water treatment, in particular to a spunlace circulating water treatment process. Background technique [0002] The spunlaced nonwoven fabric process is a method of nonwoven fabrics. It uses the continuous high-pressure ultra-fine water flow from the water needle to randomly entangle the fibers on the fiber net in all directions, and then undergoes dehydration and drying processes. Finally, a spunlace nonwoven fabric is obtained. Therefore, it has high requirements on water quality. At present, according to the raw materials of non-woven spunlace products, they are divided into one or more of cotton, polyester, spandex, PPS, fur, bamboo and wood pulp, and glass fiber. The effluent quality requirements need to meet the following standards: [0003] (1) Maximum particle size of suspended matter: <5μm; [0004] (2) Turbidity: <3NTU. [0005] The water treatment process in the prior...
