Abstract: The sensing system includes at least one chip branch. In the chip branch, a clock circuit of each sensing chip integrates the received working clock signal to obtain stable clock signal that has a relative high frequency to be subjected to frequency dividing, and a frequency dividing circuit performs frequency dividing processing on the clock signal to obtain a working clock signal required by a next-stage sensing chip. In the cascade structure, a clock source only needs to satisfy the driving requirement of a first-stage sensing chip, and the working clock signal required by each of other sensing chips is provided by a previous-stage sensing chip, such that the problem that the number of sensing chips connected in series in the chip branch is limited by the driving capability of the clock source is solved, and the applicability of the sensing system is widened.

Abstract: The present invention discloses a dosage optimization method of a chemical conditioner for deeply dewatering the sludge in a municipal wastewater treatment plant, comprises the following steps: (1) optimizing a dosage of a chemical conditioner added into a specific sludge to obtain an optimal dosage proportion of the chemical conditioner corresponding to unit mass of organic matter; (2) calculating an optimal dosage of the chemical conditioner applicable for other sludge to be treated; and (3) adding the chemical conditioner into the sludge to be treated for sludge conditioning treatment, and then performing mechanical dewatering treatment, so as to obtain a deeply dewatered sludge with a moisture content of less than 60%. By improving the reference basis as the key chemical conditioner dosage, the method can effectively solve the problem that types and moisture content range of sludge to which the chemical conditioner dosage control method is applicable are narrow.
