Problems solved by technology

However, the existing sewage treatment equipment is not very targeted for the sewage treatment of the thread factory, and the removal effect of the suspended solids is poor. The structure of the whole sewage treatment system is complex and occupies a large area, which is not suitable for some small thread factories.

Embodiment 1

[0039] according to Figure 1-4 The shown sewage treatment system for a line factory includes a buffer tank 1, a floating filter tank 2, an extended flocculation tank 3, a multi-stage filter tank 4, and a PLC controller 5 for controlling the entire system. The extended flocculation tank 3 The input end is connected with the neutralization tank 6 and the dosing tank 7 through the shunt pipe 10, and the neutralization tank 6 and the dosing tank 7 are arranged on the top of the extension flocculation tank 3, and the input end of the multi-stage filter tank 4 is passed through the intake and exhaust Pipe 11 is connected with high-temperature steam tank 8 and dilute acid regeneration tank 9;

[0040] The buffer tank 1 is arranged on the top of the fluff filter tank 2 and communicates with the fluff filter tank 2. The inside of the fluff filter tank 2 is provided with a multi-layer filter screen 12, and one side of the bottom of the fluff filter tank 2 is provided with There is a s...

Embodiment 2

[0055] according to figure 1 As shown in a sewage treatment system for a wire manufacturing factory, a sewage distribution bucket 22 is arranged on the top of the inner cavity of the floating filter tank 2, and the cross section of the sewage distribution bucket 22 is set as an isosceles trapezoid, and the top of the sewage distribution bucket 22 is Connected to the outlet of the buffer tank 1, the bottom surface of the sewage distribution bucket 22 is evenly provided with a plurality of drainage holes;

[0056] The multi-layer filter screen 12 is evenly distributed up and down, the cross section of the filter screen 12 is set to be arc-shaped, and one end away from the sealed impurity removal door 13 is higher than the other end, and the sealed impurity removal door 13 and the floating hair filter tank 2 pass through hinge connection;

[0057] The air intake pipe 11 includes a vertical pipe and a plurality of horizontal pipes, and the plurality of horizontal pipes are respec...

Abstract

The invention discloses a sewage treatment system and a sewage treatment method for a wire producing factory. The sewage treatment system comprises a buffer tank, a floating hair filtering tank, an extended flocculation tank, a multistage filtering tank and a PLC for controlling the whole system, wherein a neutralization tank and a dosing tank are connected to the input end of the extended flocculation tank through shunting tubes and are arranged at the top of the extended flocculation tank; a high-temperature steam tank and a dilute acid regenerating tank are connected to the input end of themultistage filtering tank through an air intake exhaust pipe. According to the sewage treatment system and the sewage treatment method disclosed by the invention, the PLC controls regular regeneration of the multistage filtering tank; dilute acid inside the dilute acid regenerating tank is atomized by an atomizer and then is fed into an air intake manifold; high-temperature steam also enters theair intake manifold and is mixed with the atomized dilute acid; alleviated dilute acid steam is aerated by an aeration machine and is introduced into the multistage filtering tank through the air intake exhaust pipe, so that an internal multiple flocculation precipitation layers and a filler filtering layer are regenerated; in addition, the whole sewage treatment system has the advantages of simple and compact structure, small occupied area and convenience in laying.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and method for a wire factory. Background technique [0002] Thread factory dyeing, denim washing, printing, and printing and dyeing factories will generate a lot of wastewater in the process of board washing, washing, and rinsing. The water production of printing industry in these industries is relatively small. But they all have a common feature, that is, the pollution index is relatively high, that is to say, the content of high-molecular organic matter is relatively high, and the content of suspended solids is high. It needs to be pretreated to remove most of the suspended solids. Perform up-to-standard in-depth processing. However, the existing sewage treatment equipment is not very specific to the sewage treatment of the thread factory, and the removal effect of the suspended solids is poor. The structure of the whole sewage treatment sy...
