System and method applicable to softening and reuse treatment of reclaimed water in waste incineration power plant

Abstract

The invention discloses a system and a method applicable to softening and reuse treatment of reclaimed water in a waste incineration power plant. The system comprises an adjusting pool, a mixing reaction pool, a sedimentation pool, a neutralization pool, a filtering raw water pool, a multi-medium filter and a water production pool which are sequentially connected with the reclaimed water, whereineffluent water of the water production pool is reused; the mixing reaction pool is connected with a chemical addition device; the sedimentation pool is connected with a sludge pool; the water production pool is connected with the multi-medium filter through a backwashing pump; and the multi-medium filter is provided with a backwashing water discharge end. According to the invention, treated municipal reclaimed water is used as production water of the waste incineration power plant; and the effluent quality of the system can reach the standards of reuse. The system provided by the invention hasthe advantages of good and stable effluent quality, high recovery rate, no pollution to the environment, water resource conservation, high automation degree and the like.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a reclaimed water treatment system and method suitable for waste incineration power plants. Background technique [0002] Reclaimed water is the second source of water for urban daily life. Reclaimed water treatment technology is to make full use of limited water resources, reduce urban water pressure, reduce sewage discharge, improve water quality, and make ecological harmony develop. Insufficient water resources have become an important constraint on my country's economic and social development. The regeneration and reuse of water is getting more and more attention, and the relevant state departments restrict industrial water year by year to encourage reuse and recycling. In the field of reclaimed water reuse, the coagulation process is the most basic and extremely important treatment project in industrial water. The application of coagulation and sed...

Problems solved by technology

[0003] Existing similar technologies generally only use a single flocculation sedimentation + filtration process, and the types of chemicals added are less, which does not have a good removal effect on calcium, magnesium hardness and alkalinity in reclaimed water
