Embodiment Construction

[0015] The specific embodiments of the present invention will now be further described.

[0016] (1) Wash the loofah with a diameter of 6 cm and a length of 26-30 cm, purchased in Jinan, Shandong Province, with deionized water for 2-3 times, then put it in an oven, adjust the temperature at 105 ℃ and keep it for 8 hours for drying treatment, after cooling Store in a desiccator for later use.

[0017] (2) Take out 9 loofahs processed according to the method (1) from the drying box, and fix them in the domesticated and mature activated sludge washing liquid in the washing tank with iron wire, the filling degree is 70%. At the same time, take out 1-2 pieces of loofah that have been processed according to method (1), cut and weigh 10 pieces of loofah pieces (diameter 6cm, height 3cm) with the same specifications and sizes and weighing 0.8800g, and place them in the active area. Completely submerged in the sludge. The natural loofah has a rough surface and a natural network structure ...

Abstract

The invention discloses a method for washing catering lampblack pollutants by applying loofah sponge reinforced activated sludge and application thereof. The loofah sponge is a hydrophilic / oleophylicamphoteric porous fiber plant. According to the method, the loofah sponge is cleaned and dried and is then fixed in activated sludge in a washing tank by using an iron wire for microbial biofilm formation, and then catering lampblack waste gas introduced into the washing tank is subjected to washing and biofilm treatment with the loofah sponge, thereby realizing efficient separation and conversionof gas and pollutants of catering lampblack. The loofah sponge is wide in source, low in price and biodegradable, and the method is relatively simple in treatment process and has the advantages of environmental friendliness and the like.

Description

Technical field [0001] The invention relates to the field of air pollution prevention and control, in particular to a method for washing and purifying cooking fume from a loofah intensified activated sludge and its application. Background technique [0002] In recent years, with the rapid development of the service industry dominated by the catering industry, catering oil fume pollutants have gradually become the third largest source of air pollution besides industrial exhaust gas and automobile exhaust. The cooking fume produced during food cooking and processing contains solid, liquid and gaseous pollutants. Among them, solid and liquid particles have become an important source of atmospheric fine particle pollutants, and gaseous pollutants are atmospheric fine particles. The important precursor of odor is also the main source of odor pollution. The chemical components of catering oil fume pollutants are complex and changeable, up to more than 200, mainly including aldehydes, ...
