Embodiment Construction

[0026] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] see figure 1 Flowchart of the water quality evaluation method for sludge discharge water reuse in the present invention. like figure 1 As shown, the technical solution of the present invention provides a method for evaluating the water quality of sludge discharge water reuse. The method for evaluating the quality of sludge discharge water reuse includes the steps of: 1. collecting samples of sludge discharge water; Detection; 3. Judging whether the conventional pollutant indicators in the obtained sludge discharge water have reached the standard value, so as to determine that the water quality of the adjusted or pretreated sludge discharge water reaches the water quality level of the raw water; judge the specific pollutant indicators in the obtained sludge discharge water Whether it reaches the standard value of the factory water qu...

Abstract

The invention relates to a safe evaluation method of reused water quality of sludge water in waterworks, comprising the following steps: 1, collecting sludge water samples; 2, selecting test evaluation indexes of the reused water quality of the sludge water to test; and 3, judging whether the index of conventional pollutant in the obtained sludge water reaches a standard value to determine whether the water quality of the sludge water after regulation and pretreatment meets the level of water quality of raw water; and judging whether the index of specific pollutant in the obtained sludge water reaches a standard value of water quality of output water to determine the safety of water quality of the sludge water. The technical scheme of the invention fills the gap on the quality evaluation method of sludge water both in China, solves a serial of problems of how to evaluate when the sludge is reused, how to determine whether the quality of the reused water is safe and the like, thus ensuring that the water quality test data of the sludge water is scientific and comparable. The method is capable of well guiding the safe reuse work of sludge water in waterworks.

Description

【Technical field】 [0001] The invention relates to a water quality evaluation method, in particular to a water quality safety detection method for sludge water reuse in a waterworks. 【Background technique】 [0002] The production wastewater of the waterworks mainly includes the sludge discharge water of the reaction sedimentation tank (clarification tank) and the backwash water of the filter, and its water volume accounts for about 3%-10% of the water production volume of the waterworks. The supernatant of the drainage pond (recovery pond, regulating pond), the supernatant of the mud discharge pond (concentration pond, equalization pond) and the dehydration filtrate of the sludge discharge water treatment system still belong to the category of sludge discharge water in essence, so the sludge discharge water referred to in this article is also Include this part of the water. Recycling and processing this part of water has dual meanings of saving water resources and protecting...
