Dosing device for sewage treatment equipment that automatically calculates dosing dosage by plc

Abstract

The application discloses a dosing device for sewage treatment equipment with PLC automatically calculating the dosing dose, which includes a raw water inlet pipe, a raw water outlet pipe and a drug reaction tank suspended in the air; A sphere passes through and is connected to the bottom of the drug reaction pool; several ventilation holes are evenly arranged on the sphere; at least one powdered drug box is arranged on the top of the drug reaction pool; A spray head is connected to the other end of the medicine delivery pipe; a flow sensor and a flow velocity sensor connected to the PLC are arranged on the raw water inlet pipe. After adopting the above structure, the drug reaction pool is small in size and suspended in the air, which does not occupy the actual contact space of the vehicle tool and saves the space of the vehicle tool. In addition, the dosing device can automatically calculate the dosage and frequency of dosing according to the raw water flow value and raw water velocity data in the water inlet pipe, so that the dosing dosage is accurate.

Description

technical field [0001] The application relates to a dosing device, in particular to a dosing device for mobile sewage treatment equipment. Background technique [0002] At present, the discharge of urban domestic sewage is the main pollution source of urban water in China, and the treatment of urban domestic sewage is the top priority of urban water conservation and urban water environment protection at present and in the future. This requires us to take the construction of domestic sewage treatment facilities as a priority The important content of urban infrastructure is to be grasped, and it is a matter of urgency. [0003] Sewage treatment is an important process to deal with water pollution. Use physical, biological, and chemical methods to treat industrial wastewater and domestic sewage to separate solid pollutants in water and reduce organic pollutants and eutrophic substances (mainly nitrogen and phosphorus compounds) in water, thereby reducing the impact of sewage o...

Problems solved by technology

These structures will occupy a large part of the volume of the vehicle, which does not meet the requirements of the vehicle size

[0011] 2. The metering of each drug addition is fixed, and the drug cannot be added according to the actual flow of sewage

These structures will also occupy a large part of the volume of the vehicle, which does not meet the size requirements of the vehicle

[0020] 2. The metering of each drug addition is still fixed, and it is still impossible to add drugs according to the actual flow of sewage

There is still the problem of insufficient or excessive addition of drugs
