Embodiment 1

[0029] refer to figure 1 , which is the first embodiment of the present invention, this embodiment provides a method for comprehensive treatment of industrial wastewater and operation optimization, the method for comprehensive treatment of industrial wastewater and operation optimization includes the following steps:

[0030] Various types of wastewater are aerated in the waste liquid tank 100, and sent to the quadruple tank 300 by the wastewater operation pump 200. After the coagulation reaction in the quadruple tank 300, they are quickly precipitated by the inclined tube clarifier 400, and the supernatant is Enter the final neutralization pool 500 and the effluent supervision pool 501;

[0031] The treated industrial wastewater that meets the standards enters the reuse pool 600 for reuse, and the industrial wastewater that fails to meet the standards is discharged from the effluent monitoring pool 501 back to the first waste liquid pool 101 or the fourth waste liquid pool 10...

Embodiment 2

[0039] refer to Figure 1~5 , is the second embodiment of the present invention, which is different from the first embodiment in that: it also includes the waste liquid pool 100 including the first waste liquid pool 101, the third waste liquid pool 103, the fourth waste liquid pool 104 and the first waste liquid pool Five waste liquid pools 105, wherein the first waste liquid pool 101 is an acid-base waste liquid pool, the third waste liquid pool 103, the fourth waste liquid pool 104 and the fifth waste liquid pool 105 are in communication with the desulfurization and polishing pool 106. The desulfurization and slurry pool 106 is close to the fifth waste liquid pool 105, the fourth waste liquid pool 104, and the upper part of the third waste liquid pool 103. An overflow port is dug and a gate is installed on the upper part of the pool wall. After sedimentation and reaching a high liquid level, the supernatant flows to the fifth waste liquid pool 105 , the fourth waste liquid p...

Abstract

The invention discloses an industrial wastewater comprehensive treatment and operation optimization method, which comprises the following steps: carrying out aeration treatment on various types of wastewater in a waste liquid pool, conveying the wastewater to a quadruple header through a wastewater operation pump, carrying out coagulation reaction in the quadruple header, carrying out rapid precipitation through an inclined tube clarifier, enabling supernate to enter a final neutralization pool and an effluent supervision pool, enabling the treated industrial wastewater reaching the standard to enter a reuse water pool for reuse, and enabling the treated industrial wastewater not reaching the standard to be discharged back to the waste liquid pool through the water outlet supervision pool. According to the industrial wastewater comprehensive treatment and operation optimization method provided by the invention, on the basis of existing facilities, low capital investment is achieved, the comprehensive treatment efficiency of an industrial wastewater system is effectively improved, the industrial wastewater treatment system can operate more reliably and stably for a long period, the operation safety of a unit is improved, the environmental protection risk is reduced, and the method has good macroscopic social benefits.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a method for comprehensive treatment of industrial waste water and operation optimization. Background technique [0002] A large amount of industrial wastewater will be generated during the production process, mainly including raw water pretreatment sludge discharge water, slag removal machine cooling flushing water, acid-base regeneration wastewater in the chemical water workshop, desulfurization and slurry throwing wastewater, air preheater flushing drainage, furnace shutdown protection drainage , flushing water when the unit starts, etc. Among them, raw water pretreatment mud water and slag removal machine cooling and flushing water are mainly suspended solids exceeding the standard; chemical workshop regeneration wastewater is mainly pH exceeding the standard; desulfurization and throwing wastewater mainly contains a large amount of limestone slurry suspended so...
