Application of F691 modified products in industrial wastewater treatment (2)

② FIQ-C is used in the treatment of papermaking wastewater.
The middle section wastewater and discharge outlet of a paper mill are used for comprehensive wastewater treatment.
The results are shown in Table 3-78 and Table 3-79
.

Table 3-78 Middle-stage wastewater treatment results

Table 3-79 Discharge outlet wastewater treatment results

It can be seen from Table 3-78 and Table 3-79 that the flocculant FIQ-C and PAC can be used in the treatment of papermaking wastewater, which has the best effect on the treatment of papermaking wastewater, and the treated wastewater can reach the standard discharge
.

③The application in the treatment of printing and dyeing wastewater adopts FIQ-C, which is taken from the wastewater after biochemical treatment in a printing and dyeing factory.

Table 3-80 Printing and dyeing wastewater treatment results

From Table 3-80, it can be concluded that FIQ-C has a better treatment effect on printing and dyeing wastewater, and it is more effective when used in combination with PAC
.

④Application in urban sewage treatment In order to investigate the ability of natural polymer modified chemical FIQ-C to treat urban sewage, the East Lake water of South China University of Technology was selected as the test object, FIQ-C was selected as the coagulant, and it was combined with PAM-C.

Table 3-81 Comparison of FIQ-C and PAM-C on urban sewage treatment capacity

The results in Table 3-81 show that the agent FIQ-C not only has a good turbidity removal effect, but also has a certain removal effect on COD and ammonia nitrogen
.

⑤Application in circulating cooling water The control of circulating cooling water quality is mainly to reduce turbidity, reduce the deposition of dirt, and avoid corrosion and sludge.

Table 3-82 Comparison of the flocculation performance of FIQ-C and PAM-C

Table 3-82 shows that FIQC flocs have good settling performance, and FIQC flocs have better settling performance
