Technical Field
The invention relates to the technical field of municipal sewage treatment, in particular to a municipal sewage treatment device and a treatment method.
Background
The municipal facilities refer to public facilities built by government, legal people or citizen, generally refer to various buildings, structures, equipment and the like in a planning area, and facilities and auxiliary facilities such as urban roads, urban rail transit, water supply, drainage, gas, heat, landscaping, environmental sanitation, road lighting, industrial waste medical waste, domestic sewage treatment equipment, domestic waste treatment equipment, fields and the like;
along with the development of society and the progress of economy, municipal facilities are increased day by day, the demand of cities for environment quality is increased continuously, a large amount of sewage is generated in daily municipal works, sewage treatment refers to a process of purifying the sewage when the sewage meets the water quality requirement of being discharged into a certain water body or being reused, and along with the continuous improvement of the demand of cities for environment quality, the treatment need of the sewage is also important;
sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and increasingly enters the daily life of common people, and upstream suppliers in the sewage treatment industry are mainly manufacturers of sewage treatment equipment and sewage treatment agent suppliers and belong to industries with fast development and good demand conditions.
Municipal sewage comprises domestic sewage, industrial sewage, runoff sewage and the like, is usually collected by a municipal drainage pipe network and is conveyed to a sewage treatment plant for treatment, and the main pollutants of the sewage comprise pathogen pollutants, oxygen-consuming pollutants, plant nutrients, toxic pollutants and the like; from the viewpoint of sewage source, sewage may be defined as liquid or water carrying wastes mixed with ground water, surface water, snow storm, etc. discharged from a residential, an institutional, commercial or industrial area; sewage is classified into many categories, and there are many techniques and processes for reducing the environmental impact of sewage accordingly.
And because municipal sewage not only contains a large amount of bacteria, organic pollutant in the municipal sewage, the stench that municipal sewage gived off can produce not neglectable influence to environmental quality and people's life, along with people's environmental awareness and the improvement to living environment quality requirement, also higher and higher to the requirement of municipal sewage's treatment effect.
However, the existing sewage treatment system is complex, the sewage treatment efficiency is low, the sewage treatment cost is high, the applicability is poor when a large amount of municipal sewage is treated, and after the sewage treatment system is used for a long time, the sewage treatment system cannot be applied even due to filtering blockage, manual treatment is needed, the whole sewage treatment effect is affected, the oxidative decomposition of organic substances in a water body is insufficient, and high-quality disinfection treatment is lacked, so that the sewage treatment quality cannot well meet the requirements.
