Low-energy-consumption low-carbon-emission economical energy-saving urban sewage treatment method

The invention discloses a low-energy-consumption low-carbon-emission economical energy-saving urban sewage treatment method. The method comprises the steps that: 1, the to-be-treated wastewater is collected by a sewage pipe network and then is filtered by lattices, and is lifted by a pump to enter a pulse water distribution pot of a novel efficient turn-back anaerobic biochemical pool (ABR); 2, the swage subjected to the treatment in step 1 flows into a circulation-flow biological oxidization pool; 3 the effluent water from the step 2 flows into an artificial reinforced biological contact oxidization pool reconstructed by a water body from natural tunnels and reservoirs; and 4, the effluent water from the step 2 or the step 3 flows into constructed wetlands. After the sewage is treated by the above steps, the most pollutants in the water are effectively removed and the treated effluent water reaches the standard first-grade A in GB 18918-2002 ''Discharge standard of pollutants for municipal sewage treatment plant''. The energy-saving sewage treatment purification process with low cost, low energy consumption, low carbon emission and low operating cost is particularly suitable for the sewage treatment in small towns or rural areas.

Preparation method of novel smokeless mosquito-repellent incense

The invention discloses a preparation method of novel smokeless mosquito-repellent incense, belonging to the technical field of preparation of the mosquito-repellent incense. The novel smokeless mosquito-repellent incense is prepared by the steps of preparing sludge carbon powder, preparing paste, molding the paste, drying the molded paste, spraying chemicals onto a dry mosquito-repellent incense blank, and the like. According to the preparation method, sludge carbon is taken as an incendiary agent, and an inorganic substance in the sludge carbon is taken as a flame retardant, so that not only is a new way provided for the resource utilization of the sludge carbon, but mass disafforestation caused by the mosquito-repellent incense industry is also avoided, and the preparation method of the novel smokeless mosquito-repellent incense is beneficial to environmental protection. The novel smokeless mosquito-repellent incense is non-toxic and harmless and can meet the requirement of environmental protection for the product; after the novel smokeless mosquito-repellent incense is burnt and absorbed by the human body, asthma, nerve poisoning and cancers are not caused; the novel smokeless mosquito-repellent incense has a smooth appearance, is free from fracture and mildew spots, and has the breaking-resistant strength of 425-456g and the ignition point time of 8.61-9.01h; in the burning process, smoke is not generated; the novel smokeless mosquito-repellent incense avoids a phenomenon of broken-end flameout when being burnt to an iron-tooth disk.
