Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0018] As shown in the figure, a fully automatic dosing system for electroplating sewage treatment equipment includes a first dosing system 1 for rough adjustment of the dosing amount, a second dosing system 2 for fine-tuning the dosing amount, and A dosing control system that controls the dosing dose and speed of the first dosing system and the second dosing system. Specifically:

[0019] The first dosing system 1 and the second dosing system 2 are respectively connected with the waste water pipeline 3 for conveying waste water, and the waste water pipeline 3 connected with the second dosing system 2 is located in the waste water pipeline connected with the first dosing system 1 3 Downstream, in this embodiment, it is taken that the first dosing system 1 and the second dosing system 2 are connected to the chromium reduction water tank 4 as an example....

Abstract

The invention relates to a full-automatic dosing system for electroplating sewage treatment equipment. The full-automatic dosing system comprises a first dosing system for roughly adjusting a dose, a second dosing system for finely adjusting the dose, and a dosing control system for controlling the dose and dosing speed of the first and second dosing systems; the first dosing system and the second dosing system are respectively communicated with a wastewater pipeline for conveying wastewater; and the wastewater pipeline communicated with the second dosing system is positioned at downstream of the wastewater pipeline communicated with the first dosing system. Through the two dosing systems, full-automatic dosing system automatically adds agents into the wastewater, can effectively stabilize the dose of the agents and reduce the fluctuation of the dose, effectively controls the use cost of the agents, and is safe, simple and convenient.

Description

technical field [0001] The invention relates to a fully automatic dosing system for electroplating sewage treatment equipment. Background technique [0002] At present, for wastewater discharge, electroplating wastewater discharged from factories accounts for a large proportion. The electroplating wastewater mainly comes from the cleaning of the plated parts; the washing water and waste plating solution from the filtration of the plating solution, and the waste liquid discharged from the electroplating workshop "running, dripping, dripping and leaking". The hazards of electroplating wastewater are well known. In terms of the total amount of electroplating wastewater, such as papermaking, printing and dyeing, and chemical industries, the water volume is small and the pollution area is narrow. However, due to the wide distribution of electroplating factories, the types of highly toxic substances contained in wastewater Many, it is very harmful. Untreated electroplating waste...
