Method for monitoring suspended solid SS in sludge water of water treatment plant

Abstract

The invention provides a method for monitoring suspended solid SS in sludge water of a water treatment plant, and relates to a quick water quality monitoring method for the suspended solid SS in the sludge water of each unit treatment structure. The suspended solid SS in the sludge water is changed along with the change of sludge concentration and turbidity; and by measuring the sludge concentration and turbidity of the sludge water in different stages and fitting a relation of SS and sludge concentration and turbidity change through a mathematic equation, the method realizes monitoring the SS of the sludge water of the each unit treatment structure timely. The relation of the sludge water and the sludge concentration and turbidity can be shown by the following formulas: when the sludge concentration is more than 2g/L, SS=alebx; when the sludge concentration is more than or equal to 0.5g/L and less than or equal to 2g/L, SS=a2x; and when the sludge concentration is less than 0.5g/L, SS=cy. The indexes required to be monitored are simple; the operation is convenient and quick; and the method is suitable for timely monitoring the SS of the sludge water of each unit structure of the water treatment plant, contributes to accurately adjusting and controlling sludge discharge operating condition and sludge treatment condition, and ensures the effluent quality of the water treatment plant.

Description

technical field [0001] The invention relates to a water quality monitoring method, in particular to the rapid monitoring of the suspended solid concentration SS of the flocculation, sedimentation and filtration structure discharge mud water of a water purification plant. Background technique [0002] While producing drinking water that meets the sanitary standards for domestic drinking water, the water purification plant also produces a large amount of production sludge water, which mainly comes from the sludge discharge of flocculation tanks, sedimentation tanks (clarification tanks) and backwashing of filters. The water volume generally accounts for about 4% to 7% of the total water volume of the water purification plant. Good sludge discharge operation conditions are not only an important measure to ensure the quality of effluent from water purification plants, but also have an important impact on water conservation and pollution reduction in water plants. The water qual...

Problems solved by technology

For many years, due to the long time-consuming measurement of this index, most of the water purification plants currently in operation in my country lack the actual operating SS parameters of sludge discharge, and the adjustment of sludge discharge conditions is only based on experience; the sludge discharge process design of wat
