Embodiment Construction

[0021] The present invention proposes an automatic dosing system for wastewater treatment, referring to figure 1 , which includes a chemical storage tank 11, a reactor 21, a PH meter 22, an ORP meter, a waste water tank 31, a chemical dosing pump 51, a chemical flow meter 53, a back pressure valve, a pressure sensor, a PLC controller 60, and a waste water lifting pump 41 , a proportional regulating valve 52, a waste water flow meter 42, a quantitative control module and a wireless communication module 70. Among them, the medicament storage tank 11 is preferably a container made of polymer material, which is used to hold acid, alkali, oxidizing agent, reducing agent, coagulant, flocculant or recapture agent, and the waste water pool 31 is used to hold waste water. The PH meter 22 and / or the ORP meter are set in the reactor 21 and connected to the PLC controller 60 for obtaining the reaction data of the wastewater and the medicament during wastewater treatment. The medicament d...

Abstract

The invention discloses an automatic chemical dosing system for wastewater treatment. The automatic chemical dosing system comprises: a chemical storage tank; a reactor, which is internally provided with a pH meter and/or an ORP meter; a wastewater pool; a chemical extraction assembly, which comprises a chemical feeding pump, a chemical flow meter and a back pressure valve; a wastewater pumping assembly, which comprises a wastewater lifting pump, a proportional control valve and a wastewater flow meter; a PLC, which is electrically connected with the chemical feeding pump, the chemical flow meter, the wastewater lifting pump and the wastewater flow meter separately, is connected with the proportional control valve, the pH meter and the ORP meter, and is electrically connected with the pressure sensor; a quantitative control module, which is connected with the PLC and is used for acquiring instantaneous flow information and accumulated flow information of the wastewater flow meter; anda wireless communication module, which is electrically connected with the PLC and is used for communicating with external communication equipment. According to the invention, the problems that conventional wastewater treatment systems are difficult to realize specific quantitative control and automation degrees are relatively low are solved.

Description

technical field [0001] The invention belongs to the field of waste water treatment, in particular to an automatic dosing system for waste water treatment. Background technique [0002] The physical and chemical method is often used in the pretreatment process of wastewater treatment. In the process of physical and chemical treatment, water treatment chemicals need to be added to the treated wastewater. The methods of adding chemicals include single-point dosing by dosing pump and multi-point dosing by dosing pump. Adding, gravity self-flow dosing, etc., the whole wastewater treatment system is basically used to control the dosing flow of the pump or adjust the dosage according to the opening and closing degree of the valve. Most of the operation process is human intervention, and most of them are based on excessive dosage. To maintain the stability of the system, it is difficult to achieve specific quantitative control, and the degree of automation is low. Contents of the ...
