Chemical dosing method for mobile sewage treatment equipment capable of automatically calculating chemical dosing amount and frequency

Abstract

The invention discloses a chemical dosing method for mobile sewage treatment equipment capable of automatically calculating chemical dosing amount and frequency. The chemical dosing method comprises the following steps: detecting raw water flow rate in a water inlet pipe, detecting raw water flow velocity in the water inlet pipe, calculating chemical dosing amount and chemical dosing frequency, and dosing chemical and uniformly mixing, wherein raw water during the chemical dosing in the fourth step is uniformly mixed under the action of a gas stirrer arranged at the bottom of a pressure device. After the method is adopted, the chemical reaction tank is small in size and suspended in the air, the actual contact space of a vehicle-mounted tool is not occupied, and space of the vehicle-mounted tool is saved. The chemical dosing device can automatically calculate the chemical dosing amount and frequency according to data, namely the raw water flow rate value and raw water flow velocity value in the water inlet pipe, so that the chemical dosing amount is accurate; meanwhile, powdery chemical is adopted and directly sprayed into the raw water and is mixed with gas, so that mixing is uniform.

Description

technical field [0001] The application relates to a dosing method, in particular to a dosing method 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
