CN103743871A - Method for rapidly searching leakage pint of chemical industry enterprise - Google Patents

Abstract

The invention discloses a method for rapidly searching the leakage pint of a chemical industry enterprise. The method comprises the following operating steps: sampling water containing corrosive wastewater, and establishing a technologic archive; carrying out comprehensive online monitoring of the indexes comprising the pH value, F, P and the like of the end of the above whole system, and establishing an alarm system for instantly realizing an alarm prompt when the pH value has abnormal fluctuation; and after alarm is received, instantly comprehensively analyzing the wastewater, comparing the indexes comprising the pH value, F, P, SO4<2-> and the like of the wastewater one by one, discriminating according to the relation and the proportion relation among all characteristic values, comparing with all indexes in the pre-established technologic archive to rapidly determine the possible leakage point, and carrying out onsite inspection of the possible leakage point for further determination. The method has the advantages of effective shortening of the pollution source investigation time, rapid and accurate finding of the leakage source, workload reduction, and avoiding of the influences to a downstream river.

Description

A kind of chemical enterprise leak source fast searching method

Technical field

The present invention relates to a kind of chemical enterprise leak source fast searching method.

Background technology

In chemical enterprise, because acid medium is more, often there will be that acid tube leaks, acid storage tank spill-over, or the problem such as site examining and repairing sour water discharge.Although scene is all made with anti-corrosive apparatus, but along with its working time is permanent, sour water leakage phenomenon often occurs, and owing to directly permeating the ground after sour water leakage, finally pollutes downstream river course, there is larger disguise, be all, after downstream is subject to polluting and is found, whole system to be investigated one by one, and it is large to search difficulty in the past comprehensively, efficiency is low, usually causes the accident and further expands.

Summary of the invention

For the deficiencies in the prior art part, the present invention aims to provide a kind of chemical enterprise leak source fast searching method,

Guarantee to improve finding leak source efficiency, reduce the pollution to downstream.

For solving the problems of the technologies described above, the technical solution used in the present invention: a kind of chemical enterprise leak source fast searching method, comprises following operation steps:

(1) all water quality that contains corrosive wastewater is sampled, set up technology files;

(2) end of whole system is carried out to comprehensive on-line monitoring of the indexs such as pH value, F, P, set up warning system, when unusual fluctuations appear in pH value, carry out immediately alarm;

(3) receive after warning, immediately waste water is carried out to multianalysis, to pH value, F, P, the SO in waste water ₄ ^2-etc. index with compare one by one,, proportionate relationship irrelevant by having between each eigenwert screened, and contrast with the indices in the technology files of setting up early stage, can judge rapidly suspicion leakage point, and the suspicion of finding out is suspected to be to leakage point carries out site inspection, further determine.

Adopt the technical program, can shorten the time of investigation pollution source, accurately find relatively rapidly source of leaks, reduced workload, avoid the impact on downstream river course.

Embodiment

Embodiment, the leakage point of Wengfu phosphate fertilizer plant is searched.

First by all water quality that contains corrosive wastewater of Wengfu phosphate fertilizer plant is sampled in a large number, know the real situation comprehensively, and set up relevant pollution source index archives, the end of whole system is carried out comprehensive on-line monitoring of the indexs such as pH value, F, P simultaneously, set up warning system, when unusual fluctuations appear in pH value, alarm immediately, receive after warning, immediately waste water is carried out to multianalysis, by pH value, F, P, SO in waste water ₄ ^2-etc. index, compare one by one,, proportionate relationship irrelevant by having between each eigenwert, etc. screen, and with the pollution source index archives of setting up early stage, contrast, by corresponding relation, judge rapidly the most possible leakage point that is suspected to be, and the leakage point that is suspected to be of finding out is carried out to site inspection, thereby find accurately rapidly source of leaks, avoid the impact on downstream river course.

Claims (1)

1. a chemical enterprise leak source fast searching method, is characterized in that comprising following operation steps:

(1) all water quality that contains corrosive wastewater is sampled, set up technology files;

(2) end of whole system is carried out to comprehensive on-line monitoring of the indexs such as pH value, F, P, set up warning system, when unusual fluctuations appear in pH value, carry out immediately alarm;

(3) receive after warning, immediately waste water is carried out to multianalysis, to pH value, F, P, the SO in waste water ₄ ^2-etc. index with compare one by one,, proportionate relationship irrelevant by having between each eigenwert screened, and contrast with the indices in the technology files of setting up early stage, can judge rapidly suspicion leakage point, and the suspicion of finding out is suspected to be to leakage point carries out site inspection, further determine.
