The first ultrasonic level gauge 12 and the second ultrasonic level gauge 41 may be selected from conventional types, such as siemens' 7ML52211DA11 type ultrasonic level gauges.
The semiconductor material grinding wastewater sludge treatment system comprises the following specific working processes:
when the sewage level in the sludge wastewater tank 10 reaches a set value of 1.2 m (displayed by an ultrasonic level indicator), the stirring paddle 11 is driven by the servo motor, the servo motor is electrified to drive the stirring paddle 11 to rotate so as to carry out stirring operation, so that the sludge deposited at the bottom of the sludge wastewater tank 10 floats up, and then the wastewater containing the sludge is conveyed to the filter press 20 through a water pump 52 (a stainless steel screw pump). The one-way valve 53 can be vertically installed on the pipeline to prevent the sludge-containing wastewater from flowing back to the sludge wastewater tank 10 through the first valve 51 after the stainless steel screw pump stops working. The three-way regulating valve 61 is arranged, when the pressure of the pipeline where the feed inlet of the filter press 20 is positioned is too high, a part of sewage can flow back to the sludge wastewater tank 10 through the first connecting pipe 63, and therefore the pressure of the pipeline where the feed inlet of the filter press 20 is positioned is effectively reduced; the three-way regulating valve 61 can preset a pressure value according to the process requirements, and the normal operation of the working pressure within a range is ensured. Install three-way control valve 61 additional, through three-way control valve 61's automatically regulated pressure, guarantee that equipment pressure is stable and continues work in the setting value. For example, after the filter press 20 is operated for a period of time, the pressure of the pipeline at the feed inlet of the filter press 20 is increased, the pressure in the filter press 20 is adjusted by the three-way adjusting valve 61 to be not more than 0.5Mpa, and is continuously kept until no water flows out of the drain valve of the filter press 20 or the liquid level of the sludge wastewater tank 10 is lower than 0.2 m, so that one filter press operation is completed, the treated sludge is cake-shaped, the water content is less than 40%, and the clean water in the filter press process flows downwards to the clean water tank 30 and then flows to the clean water tank 40 through the second connecting.
Wherein, the stirring paddle 11 is used for uniformly stirring the mud-containing wastewater to prevent the mud from precipitating. The filter press 20 functions to filter the wastewater containing sludge to separate sludge from clear water. The clean water tank 40 is used for storing the clean waste water after the filter pressing of the filter press 20.
Further, a second valve 71 and a self-priming pump 72 are arranged outside the clean water tank 40, a second drain hole is formed in the bottom of the clean water tank 40, the input end of the second valve 71 is communicated with the second drain hole, and the output end of the second valve 71 is communicated with the input end of the self-priming pump 72. When the liquid level in the clean water tank 40 reaches a set height, the self-priming pump 72 operates, and clean water in the clean water tank 40 can be discharged to a designated place for centralized treatment, for example, can be sent to a self-built waste water pipe network of our company; when the liquid level is reduced to the set parameter (0.2 m), the self-priming pump 72 is closed, and finally the sludge is bagged and outsourced.
In the embodiment, the semiconductor material grinding wastewater sludge treatment system can solve the problems of long sludge filter-pressing process time, large pressure of a conveying pipeline and high moisture content of sludge after wastewater treatment.
