Problems solved by technology

However, such a process requires the use of a large amount of chemicals, which remain in the treated wastewater, which brings many restrictions on the reuse of wastewater.
[0011] And neither of the two patents considers the issue of fiber recovery in wastewater, wasting the fiber in wastewater

Embodiment 1

[0035] figure 1 It is a schematic diagram of the equipment connection relationship of the present invention. It can be seen from the accompanying drawings that the present invention includes a waste water tank, a first flocculation settlement tank, a fiber recovery device, a second flocculation settlement tank, a biodegradation tank, a sludge tank and a reuse water tank. The waste water pool is connected to the waste water discharge pipeline from the papermaking workshop, the waste water in the waste water pool is transported to the water inlet end of the first flocculation settling tank through the waste water pipeline, and the water discharge end of the first flocculation settling tank passes through the pipeline Connect to the water inlet end of the fiber recovery device, the water discharge end of the fiber recovery device is connected to the water inlet end of the second flocculation settlement tank, and the water discharge end of the second flocculation settlement tank is...

Embodiment 2

[0040] There are more than two first flocculation-settling tanks, and more than two first flocculation-settling tanks are connected in series, and the water discharge end of the first flocculation-settling tank is connected to the inlet of the adjacent first flocculation-settling tank. At the water end, all the first flocculation and settling tanks share a sludge tank.

[0041]The connection relationship of the waste water tank, the fiber recoverer, the second flocculation and sedimentation tank, the biodegradation tank, the sludge tank and the reused water tank is the same as that of Embodiment 1.

Embodiment 3

[0043] The second flocculation-settling tank has more than two, and more than two second flocculation-settling tanks are connected in series, and the water discharge end of the second flocculation-settling tank is connected to the inlet of the adjacent second flocculation-settling tank. At the water end, the upper, middle and bottom layers of all the second flocculation-settling tanks are respectively provided with drainage pipes connected to the biodegradation tank, return pipes connected to the first flocculation-settling tank and sewage pipes connected to the sludge tank, All the second flocculation settling tanks share one sludge tank.

[0044] The connection relationship of the waste water tank, the fiber recoverer, the first flocculation and sedimentation tank, the biodegradation tank, the sludge tank and the reused water tank is consistent with that of Embodiment 1.

Abstract

The invention discloses an operating method of a wastewater treatment system. The wastewater treatment system comprises a wastewater tank, a first flocculation sedimentation tank, a fiber recovery device, a second flocculation sedimentation tank, a biodegradation tank and a reuse water tank, wherein the wastewater tank is connected to the water inlet end of the first flocculation sedimentation tank; the water outlet end of the first flocculation sedimentation tank is connected to the water inlet end of the fiber recovery device through a pipeline; the water outlet end of the fiber recovery device is connected to the water inlet end of the second flocculation sedimentation tank; the water outlet end of the second flocculation sedimentation tank is connected to the water inlet end of the biodegradation tank; the water outlet end of the biodegradation tank is connected to the reuse water tank; a sludge tank is arranged at the bottom of the first flocculation sedimentation tank; the second flocculation sedimentation tank comprises an upper layer, a middle layer and a bottom layer; a water discharge pipe connected to the biodegradation tank, a return pipe connected to the first flocculation sedimentation tank and a sludge discharge pipe connected to the sludge tank are respectively connected to the upper layer, the middle layer and the bottom layer. The operating method is thorough in wastewater treatment effect, low in energy consumption and beneficial to popularization and application.

Description

technical field [0001] The invention relates to a low-consumption papermaking wastewater treatment system, which belongs to the field of industrial wastewater treatment. Background technique [0002] Water is the source of life. The worldwide water scarcity problem is becoming more and more serious. Water conservation has always been advocated. As a large water consumer, industrial production industries should do a good job in reducing industrial water discharge, improving water recycling rate, and avoiding industrial waste. Waste of water. [0003] At the same time, the problem of environmental pollution is becoming more and more serious. Improving environmental awareness and reducing pollutants, especially the discharge of sewage or wastewater from industrial production, is one of the important causes of environmental pollution. How to deal with the discharge of industrial sewage or wastewater has become a key factor in reducing environmental pollution an important measur...
