Abstract

The invention discloses a recycle method of recycled water, which comprises the steps of: mixing cooked wastewater with the recycled water by the biochemically-treated and deeply-treated discharged water; and treating the mixed water through a lime+flocculation precipitating working procedure, a multi-medium filtering working procedure, a filtering working procedure by active carbon, a softening working procedure by a softener, an ultra-filtering working procedure and a reverse osmosis working procedure to obtain recycling water, wherein the recycling water is used as compensating water of circulating water, greening water, boiler water or fire fighting water. The recycle method of the recycled water can be used for wholly recycling the cooker wastewater; and the recycle method of the recycled water is used for mixing the cooked wastewater with the recycled water such as the circulating water wastewater, deoxidization station reverse osmosis concentrated water, the boiler wastewater and the like through the biochemically-treated and the deeply-treated discharged water and then treating the mixing water together, so that the quality of the recycled water is improved, the treatment difficulty is reduced, and the recycled water is high in yield and low in cost.

Description

technical field

[0001] The present invention relates to a water treatment method, in particular to a process in which the effluent of coking wastewater after biochemical and advanced treatment is mixed with reclaimed water such as circulating water sewage, reverse osmosis concentrated water from a desalination station, and boiler sewage. Water reuse methods. Background technique

[0002] The coking wastewater produced in the production process of coal chemical enterprises is complex in composition and belongs to toxic and harmful organic wastewater. After biochemical treatment, there are still certain harmful substances that are difficult to degrade. Moreover, the water contains a large amount of chloride ions. Only by further removing these substances, It can be used as supplementary water for circulating water. Coal chemical production also requires a large amount of circulating cooling water. In order to ensure the quality of circulating cooling water, it is necessary to...
