Chemical water treatment equipment

Abstract

The invention relates to chemical water treatment equipment. The equipment comprises a raw water tank, a multi-media filter, an activated carbon filter, at least two reverse osmosis equipment groups,a decarbonization tower, an intermediate water tank, an intermediate water pump, a mixing bed device and at least one desalination water tank which are connected in sequence, wherein the reverse osmosis equipment groups are connected in parallel. The raw water tank is connected to a water supply system of a factory pipe network, the bottom of the multi-media filter is connected with a ventilationpipe for introducing compressed air into the multi-media filter, and the ventilation pipe is connected with a pressure reducing device. Bypass pipes with control valves are also connected to water inlet pipelines and water outlet pipelines of the multi-media filter and the activated carbon filter, and an water outlet pipe of the activated carbon filter is also connected with a second dosing device. Most of water enters the decarbonization tower after being treated through the reverse osmosis equipment groups, less part of the water enters a backwash water tank, and the water in the backwash water tank is pumped into the multi-media filter and the activated carbon filter through a backwash water pump. The water treated through the desalination water tanks is pumped into a boiler deaerator through a desalination water pump.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a chemical water treatment equipment whose water source is river water. Background technique [0002] At present, the water source is the river water treatment device as attached figure 1 As shown, including multi-media filter, activated carbon filter, precision filter, high-pressure pump, reverse osmosis device, decarbonization tower, intermediate water tank, intermediate water pump, mixed bed device, desalted water tank, desalted water pump and boiler deaerator, etc. equipment, the treatment device mainly has the following deficiencies when it operates to treat water: The SDI of the water filtered by the multi-media and activated carbon filter is greater than 4, which cannot meet the requirements of subsequent treatment, resulting in easy fouling of the reverse osmosis membrane; Once the equipment breaks down, water cannot be produced continuously, which seriously affects the op...
