Ultrasonic combined waste water treatment process and system of refuse leachate

Abstract

The invention relates to an ultrasonic combined waste water treatment process of refuse leachate, relating to the technical field of waste water treatment and recycling of resources and environmental protection. The ultrasonic combined waste water treatment process of the refuse leachate comprises the following steps of: enabling waste water to enter a regulating pond; treating colloids, amphoteric substances and heavy metals in a coagulation sedimentation pond; eliminating ammonia nitrogen in an ultrasonic catalytic oxidation pond; sequentially sedimentating through biological treatment in an ABR (Acrylate Butadience Rubber) baffle plate anaerobic pond, a hydrolytic pond, a facultative pond and an aerobic pond; filtering in a CMBR (Chatter Membrane Bioreactor); eliminating waste gases and stench in a carbon filter pond; disinfecting in a contact disinfection pond; and filtering in an RO (Reverse Osmosis) membrane reverse osmosis system so as to obtain water meeting the requirements for emission standards. The invention also provides a treatment system for the ultrasonic combined waste water treatment process. The ultrasonic combined waste water treatment process and system can obtain the outflow water with stable quality by treating the refuse leachate; the treatment system has the advantages of small size and occupying area, high efficiency, low energy consumption and easy realization for mechanical-electrical integration control and management; and in addition, the invention is beneficial to the protection of the original landscapes of a construction party by adopting a non-buried type structure and also reduces the influence of the operation of the treatment system on an office area.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a garbage permeate liquid ultrasonic combined waste water treatment process and a treatment system thereof. Background technique [0002] Garbage permeate is highly difficult and high-concentration wastewater containing organic pollutants, viruses, germs, humic acid, ammonia nitrogen, phenol, and various heavy metals. It is difficult to discharge up to standard using traditional sewage treatment processes. At present, the process methods commonly used at home and abroad are complicated, occupy a large area, consume a lot of energy, and the quality of effluent water is difficult to meet the reuse standard. For example, "a kind of garbage permeate treatment device" disclosed in Chinese Patent No. 200520098030.7: the bottom of the container is connected to a liquid outlet pipe with a gate valve, a filter is installed at the interface between the bottom of the container...

AI Technical Summary

Problems solved by technology

The main disadvantages of the air stripping process are: (1) need to build a large melting pool; (2) the cracking furnace needs to work in an environment of 200-600 ° C, which consumes a lot of energy and has a high temperature; (3) it is difficult to crack Stupid substances

(4) Hydrogen cyanide cannot be recovered after stripping
