This paper mainly introduces the design of the chlorinating room of the Seventh Water Plant of Datong City, including the water quality features, main water purifying processes, engineering design scale, technical design and equipment selection of the chlorination room, the composition, working principle, design points of V- 100 type chlorinating system, and the main functions of the equipment.

The effects of thermal shock and chlorination on the recovery of chlorophyll a in seawater;

Based on existing problems in chlorine disinfection process,improvements were suggested from four aspects-setup of chlorination point,appropriately choice of chlorine dosage,mixing efficiency of chlorination,controlling measure of adding chlorine in order to enhance disinfection efficiency,reduce disinfection by-products and control production cost.

Application of RSview configuration software in Chlorine dosing and Ammonia dosing syetems;

Chlorine dosing in waterworks is the most crucial part.

The aim of the chlorine dosing system is to make sure that the residual chlorine is qualified.

The principle of adding chlorine and adding pharmaceutical is given on the basis of water Plant s craft.
