Problems solved by technology

[0005] The treatment of landfill leachate is a very difficult social problem. The leachate flowing into the farmland can destroy the soil, make the land wasteful, pollute the crops and make them unusable, and even make people sick
Leakage of leachate in Jilin Province caused 1,800 wells in dozens of square kilometers to be polluted and scrapped
Leachate leakage from the Jiamusi landfill caused the city’s largest water source, the No. 6 Water Treatment Plant, to be scrapped

Embodiment 1

[0036] Take the production of 1 ton of JQC treatment agent as an example. It is divided into 1#drug and 2#drug.

[0037] ①Producing 1# treatment agent

[0038] Measure 500kg of hydrochloric acid into an enamel reaction tank, add 338kg of water, start stirring, gradually add 150kg of aluminum ash, 10kg of alumina, and 2kg of iron oxide, and continue to stir and react for 5 hours until the Baume degree reaches 1.20. Stop the reaction and cool to normal temperature. 1#treatment agent.

[0039] ②Producing 2# treatment agent

[0040] Weigh 250kg of calcium carbonate, 20kg of bleaching powder, add 730kg of water, and stir evenly to obtain 2# treatment agent.

Embodiment 2

[0042] ①Producing 1# treatment agent

[0043] Measure 350kg of hydrochloric acid into an enamel reaction tank, add 340kg of water, start stirring, gradually add 300kg of aluminum ash, 4kg of aluminum oxide, and 5kg of iron oxide, continue to stir and react for 3 hours, until the Baume degree is 1.30, stop the reaction, and cool to normal temperature. 1#treatment agent.

[0044] ②Producing 2# treatment agent

[0045] Weigh 80 kg of calcium carbonate, 100 kg of bleaching powder, add 820 kg of water, and stir evenly to obtain 2# treatment agent.

Embodiment 3

[0047] The operation of processing landfill leachate.

[0048] The amount of sewage to be treated is 10 tons. Add 3kg of JQC 1# treatment agent for the first time, add in front of the pump, and stay for 30 minutes; add 2kg of 1# treatment agent for the second time, and settling time 15 minutes; enter the disinfection tank and add 1kg of 2# treatment agent for the third time, and stay 20 minutes. Processing is complete.

Abstract

An efficient treating agent No.1 or No.2 for the seeping liquid of garbage burying field is prepared from alumnium oxide, aluminium ash, iron oxide, hydrochloric acid, calcium carbonate and bleaching powder. Its JQC treating technology is also disclosed, which features high effect, simple process, and low cost.

Description

Technical field [0001] The invention relates to a method for treating landfill leachate, in particular to a production method and treatment process of a high-efficiency treatment agent (code JQC) for landfill leachate in urban garbage landfills. Background technique [0002] Landfill leachate refers to the high-concentration sewage produced by the waste and the overlying soil after rainwater that exceeds the water holding capacity and surface evaporation potential of the overlying soil layer of garbage enters the landfill. The leachate contains a lot of toxic and harmful substances such as bacteria, viruses, and parasites of waste organic matter. The treatment of landfill leachate at home and abroad is very difficult and the most troublesome problem. Its complicated composition and many factors will cause great inconvenience to the treatment. If it is directly discharged without treatment, it will cause serious environmental problems. Pollution endangers people's health. The main...
