And the on-line monitoring research of indexes such as turbidity, ozone concentration and the like is carried out, the operation state of equipment is displayed on line in real time and fault alarm is carried out by utilizing the PLC and sensor technology, intelligent diagnosis and fault early warning are carried out according to on-line monitoring parameters, and the high-efficiency and stable operation of the system is ensured.
The on-line detection of residual chlorine, on-line turbidity monitoring and on-line detection of ozone concentration in the water of the oxidation tower are carried out. The on-line detection of residual chlorine in the regulating tank 5 of the domestic sewage treatment device aims at monitoring the residual chlorine in sewage entering the equipment, and when the residual chlorine in the sewage is higher than a value born by a system, a neutralizing agent is automatically added so as to reduce the influence of a strong oxidant on bacteria in a biochemical section of the system. On one hand, the on-line monitoring of the turbidity in the clean water tank of the marine domestic sewage treatment device can ensure the treatment quality, and on the other hand, the fault early warning can be carried out on the condition of membrane breakage. The concentration of ozone in water in the oxidation tower is an important basis for measuring the disinfection state of the system, and when the concentration of ozone in water is lower than the limit value of 2.5mg/L, a fault alarm is sent. In the test, the floating range of the ozone concentration in the clean water is required to be touched, and the low ozone concentration alarm value is determined in a small test mode. In addition, the ozone generator is provided with an environmental ozone monitoring function from the safety perspective, when ozone leakage occurs and ozone in the environment reaches a set value, the ozone generator alarms and stops, so that the harm of ozone leakage to personnel can be effectively prevented.
In addition to the embodiments described above, other embodiments of the utility model are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the utility model.
