Problems solved by technology

[0022] In order to solve the problems of low ammonia removal efficiency, unstable operation, the whereabouts of ammonia gas generated in the process of ammonia blowing and other problems in the ammonia stripping process used in the current method of reducing ammonia nitrogen and COD content in the garbage leachate treatment process, as well as the biochemical system. The fluctuation of water quality is obvious, which seriously affects the stable operation of the biochemical system and the quality of effluent water. The present invention proposes a treatment method and system for garbage leachate, which uses rectification to remove the evaporated condensed water of garbage leachate Ammonia treatment, which effectively solves the problems of low ammonia removal efficiency, unstable operation, and the whereabouts of ammonia gas generated during the ammonia stripping process in the process of deammonization of high-concentration ammonia-nitrogen wastewater by the ammonia stripping method and the biochemical system. The influent water quality fluctuates significantly, seriously affecting the stable operation of the biochemical system and a series of problems such as the effluent water quality
[0023] One of the technical problems to be solved by the present invention is to provide a method for treating leachate in a waste incineration plant, which can effectively solve the problems of low ammonia removal efficiency, low operating Instability, the whereabouts of ammonia gas generated during the ammonia stripping process, and a series of problems such as obvious fluctuations in the influent water quality of the biochemical system, which seriously affect the stable operation of the biochemical system and the quality of the effluent water

Embodiment Construction

[0056] The garbage leachate treatment method that the present invention proposes comprises following processing steps:

[0057] a. Adding a coagulant to the leachate for coagulation and sedimentation pretreatment to remove suspended solids;

[0058] b. Evaporating and concentrating the pretreated leachate to obtain condensed water and remove pollutant residues and raffinate;

[0059] c. The pretreated condensed water is subjected to ammonia distillation to remove ammonia nitrogen;

[0060] d. The ammonia-distilled water is treated with biochemical organic matter removal and biological denitrification, so that it can reach the first-level discharge standard (including total nitrogen index) of the "Comprehensive Wastewater Discharge Standard" (GB8978-1996) or industrial reuse .

[0061] In the step a, the pH value of the leachate is controlled at 10.0-10.5; in the step b, the evaporation temperature of the first evaporation tank is controlled to be 105-130°C, and when multi-ef...

Abstract

The invention discloses a garbage leachate disposal method and system, aiming at solving the problems of low ammonia removal efficiency, instability in operation, ammonia direction in an ammonia blowing-off process of the ammonia blowing-off technology adopted by the method for reducing ammonia nitrogen and chemical oxygen demand (COD) content in the existing garbage leachate disposal process, and a series of problems of remarkable inlet water quality fluctuation of a biochemical system, serious influence on stable operation and outlet water quality of the biochemical system. According to the garbage leachate disposal method and system disclosed by the invention, ammonia removal treatment is implemented on evaporating condensed water of the garbage leachate by a rectifying method, so the problems of low ammonia removal efficiency, instability in operation, ammonia direction in an ammonia blowing-off process in the process of operating the ammonia removal process of the high-concentration ammonia nitrogen wastewater of the existing ammonia blowing-off method, and a series of problems of remarkable inlet water quality fluctuation of the biochemical system, serious influence on stability in operation and outlet water quality of the biochemical system are effectively solved.

Description

technical field [0001] The invention relates to a sewage treatment method, and also to a system for realizing the process, more specifically, to a garbage leachate treatment method and system. Background technique [0002] With the rapid development of the economy, the continuous improvement of people's living standards and the rapid development of modern cities, the urban domestic waste has also increased rapidly, and the pollution of domestic waste has become increasingly prominent. At present, domestic waste treatment methods mainly include incineration, composting, mechanical treatment and landfill. The traditional landfill treatment of municipal solid waste is subject to more and more restrictions. According to the basic principles of harmlessness, reduction and recycling of municipal solid waste, domestic waste incineration power generation has become a solution to urban domestic waste in recent years. New direction, the construction of waste incineration plants has d...
