Purifying method for sewer of caravan

Abstract

The invention provides a purifying method for a sewer of a caravan. The purifying method comprises the following steps: 1) allowing sunlight to pass through a Fresnel lens, focus on a light collecting block and to be transmitted to a main optical fiber, then allowing the sunlight to pass through the main optical fiber and transmitting the sunlight to a scattering head of a photosynthetic bacterium culture cage via the main optical fiber, wherein light emitted by the scattering head provides a light source for the photosynthetic bacterium culture cage; (2) allowing green sulphur bacteria, red sulphur bacteria and Rhodospira bacteria suspended in a nutrient solution in the bacterium culture cage to be propagate under irradiation of sunlight, wherein the green sulphur bacteria, red sulphur bacteria and Rhodospira bacteria can mature in 7 days; and (3) closing an outlet valve of the sewer, opening a butterfly valve of an output pipe and allowing the green sulphur bacteria, red sulphur bacteria and Rhodospira bacteria cultured in the step 2 to flow into the sewer. The method can prevent microbial corrosion to a pipeline by harmful bacteria, realizes purification of an environment in the sewer and prolongs the service life of the pipeline of the sewer.

Description

technical field [0001] The invention belongs to the field of caravan technology. Background technique [0002] The RV is a fashion facility car type imported from abroad. The home facilities on the car include: bedding, stoves, refrigerators, cabinets, sofas, dining tables and chairs, bathroom facilities, air conditioners, TVs, audio and other furniture and electrical appliances, which can be divided into Driving area, living area, bedroom area, sanitation area, kitchen area, etc. RV is a fashion product that integrates "clothing, food, housing, and transportation" to realize "travel in life, life in travel". [0003] The RV integrates the areas needed for people's life, such as kitchen, toilet, shower room, etc. The wastewater generated in these areas will be directly discharged into the sewer of the RV for storage, and then discharged when the RV moves to the specified discharge point. However, when the caravan travels on the road for a long distance, sometimes the distan...

AI Technical Summary

Problems solved by technology

However, when the caravan travels on the road for a long distance, sometimes the distance between the two discharge points on the road is very far, which leads to the storage of sewage and wastewater in the sewer of the caravan for too long, and the number of microorganisms will gradually increase. This situation brings The hazards are: harmful bacteria in microorganisms such as sulfide-producing bacteria, sulfate-reducing bacteria, iron bacteria, etc., the metabolites of these harmful bacteria have microbial corrosion, which makes the corrosion depth of the sewer pipeline faster and shortens the service life
