Pond type electrochemical water treatment device and method

Abstract

The invention discloses a pond type electrochemical water treatment device and method, and relates to the technical field of water treatment. The device comprises a cooling water pond body, positive electrode plates and negative electrode plates, wherein a water inlet and a water outlet are formed in both sides of the cooling water pond body respectively, an insulating wall formed by an insulatingplate is arranged on the inner wall of the cooling water pond body, n+1 negative electrode plates and n positive electrode plates are alternately arranged on the inner side of the cooling water pondbody to form a plurality of direct current parallel electric fields, water to be treated flows through the negative electrode plates and the positive electrode plates along a S-shaped flow path, and connecting columns are arranged on the upper sides of the positive electrode plates and the negative electrode plates. According to the pond type electrochemical water treatment device provided by theinvention, the wall of the cooling water pond is used as a shell, a manner of adjusting measures to local conditions is adapted, namely, an original water pond is used for playing a new role, a treater shell is not needed any longer, the treatment of full amount of return water and flow-out water is ensured, and electrical floatation, electrical adsorption and electro-catalytic oxidation are integrated. The device and method can be used for treating high-hardness, high-alkali, high-chlorine-ion and high-conductivity circulating water, and are low in cost, long in operating service life, and capable of saving water and protecting environment.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a pool-type electrochemical water treatment device and method. Background technique [0002] The newly revised laws and regulations "Regulations on Environmental Protection Management of Construction Projects", the "Water Pollution Prevention and Control Law" implemented on January 1, 2018, and the "Zero Discharge" instructions issued by provincial-level localities to power plants and paper-making water polluters have prompted Enterprises and water shortage projects, especially enterprises with large water volume, high hardness, high alkalinity, and high chloride ions, are seeking pollution-free and zero-emission water treatment technologies in many ways. The current chemical agent method, electrodialysis, reverse osmosis, etc. Due to the secondary pollution that cannot meet the environmental protection requirements, electrochemical water treatment technology has attracte...

AI Technical Summary

Problems solved by technology

[0007] (3) Both fully automatic and semi-automatic are bypass installations and can only handle 8% of the maximum circulating water volume, for example, 15000m 3 / h circulating water, dozens of units need to be installed, covering a large area, many accessories, and a large investment

[0011] (3) The processor installed in the pool is customized according to the specifications of the pool. If the pool is 6m deep, the processor is also 6m high, and it can handle 5000m 3 / h-12000m 3 More than 16 sets / h of water need to be installed, the volume is large, the required pool area is also large, the installation and maintenance amount is large, and the input cost is also large.

[0012] To sum up, the current electrochemical water processor treats a flow rate of 15,000m 3 It is technically difficult to circulate water with water hardness above 400mg / l per hour.
