Abstract

The invention discloses an automatic metering seawater pretreatment environment-friendly chlorination system which comprises a sodium hypochlorite storage tank, a medicine outlet pipe, a first medicine adding branch, a second medicine adding branch, a third medicine adding branch and a fourth medicine adding branch. The system is characterized in that the medicine outlet pipe is arranged on one side of the sodium hypochlorite storage tank; a medicine outlet control valve is installed on the medicine outlet pipe, the medicine outlet pipe is communicated with the sodium hypochlorite storage tank, the first medicine adding branch, the second medicine adding branch, the third medicine adding branch and the fourth medicine adding branch are all arranged on one side of the medicine outlet pipe,and the first medicine adding branch, the second medicine adding branch, the third medicine adding branch and the fourth medicine adding branch are all communicated with the medicine outlet pipe. Theautomatic metering function of the system is formed by the liquid level meter on the sodium hypochlorite storage tank, the diaphragm metering pump, the mechanical flow meter of the medicine adding pipeline and the like, and the operator can comprehensively compare the three modes to obtain the most accurate metering adding amount.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to an automatic metering seawater pretreatment environment-friendly chlorination system. Background technique [0002] At present, since ammonia nitrogen is a main indicator of desalinated water, it is necessary to ensure that the ammonia nitrogen is qualified. To ensure that the ammonia nitrogen of the product water is qualified, according to the desalination operation regulations, the residual chlorine value of the effluent of seawater pretreatment is required to be 0.2-0.4mg / L. [0003] When the peak growth period of marine organisms comes in summer or other seawater quality changes, the electrolytic chlorine production device cannot meet the demand for seawater chlorination, and if there is no automatic chlorination device in the pretreatment area, the quality of seawater pretreated by the power plant will deteriorate significantly. Generally, in a power plant with...
