An industrial sewage recycling system

Abstract

The invention provides an industrial wastewater recycling system, which is characterized in that a cold water pool is arranged above a water collection pool, and the lower end of the cold water pool is communicated with the water collection pool; a travelling crane rail frame extends left and right and extends leftwards for a certain length from the position right above the water collection pool, and a transfer car is arranged right below the travelling crane rail frame; a transfer car rail extends to sintering equipment; a rail matched with a travelling crane is arranged on the top face of the travelling crane rail frame; a winding machine is arranged on the travelling crane, and a dirt collector is connected to the lower end of a cable wire of the winding machine; a new water supplementation pool is communicated with the water collection pool; the water collection pool is communicated with a circulating water pool, the circulating water pool is connected with a circulating water pump, the circulating water pump is connected with a water consumption unit, and the water consumption unit is communicated with the upper port of the cold water pool; the peripheral wall of the dirt collector is mesh-shaped, an electric flocculation device is fixed in the peripheral wall, and an electric valve is arranged at the lower end of the dirt collector in a manner of corresponding to a sludge discharge opening in a precipitation area of the electric flocculation device. The industrial wastewater recycling system can be used for reducing the quantity of wastewater effluent of a circulating water system in a coking production process, eliminating the existing secondary pollution and recycling wastes to produce good economic benefits and environmental benefits.

Description

technical field [0001] The invention relates to the field of sewage treatment systems in the coking industry, in particular to an industrial sewage recovery and recycling system. Background technique [0002] With the increasing demand for resources in the process of economic development, the shortage of water resources and environmental protection problems are becoming more and more serious. In order to solve the contradiction between water shortage and economic development, improving the reuse rate of industrial water has become the key to saving water and reducing pollution. According to preliminary statistics, the water consumption of the circulating water system accounts for more than 70% of the total industrial water consumption, so increasing the concentration of industrial circulating water will effectively increase the water reuse rate, reduce the sewage discharge of enterprises, and achieve environmental protection effects. [0003] At present, traditional water t...

Problems solved by technology

In short, the current water recycling treatment system in steelworks still has a large amount of sewage discharge, and the increase in output value is directly proportional to the increase in sewage discharge. Therefore, it is not in harmony with the environmental protection requirements and sustainable concepts of the development of coking enterprises, and will definitely become a constraint. A Huge Obstacle to the Improvement of Economic Benefit and Market Competitiveness of Coking Plant
