Description

Family, rural area apparatus for treating sewage

Technical field

This utility model relates to a kind of sewage disposal device, particularly a kind of family, rural area apparatus for treating sewage.

Background technology

Along with China's expanding economy, the pollution condition of country sewage is also on the rise, and has become as The important sources of rural pollution.1. from the perspective of environment, Background of Academic Resources, China's major part rural area Sanitary sewage be in the state without any process just arbitrarily discharge, the overall ecological environment to rural area Cause huge destruction, also constitute threat greatly to the drinking water safety of vast farmers simultaneously. Furthermore, the river overall water quality of rural area is deteriorated, and exceeds standard seriously based on the nutrient substance of nitrogen, phosphorus, Partial rivers, lake have presented serious eutrophication state.Through investigation, to life in present rural area The discharging modes of sewage have two kinds: one to be arbitrarily to splash, two be beat in institute " water-retention well ", by sewage All permeate the ground.The first sewage discharge mode, can make the environment of surrounding become stench, mosquitos and flies taste Raw；The second sewage discharge mode, by direct polluted underground water resource, i.e. pollutes most of rural area Drinking water.Now, there is substantial amounts of crowd in the whole nation because environment and water pollute infects intestinal disease, very To dying.This particularly problematic in the rural area that China is vast.Next, China is one and lacks The country that water is serious, although gross amount of water resources is 28000 billion cubic meters, and position is at the forefront in the world, but Due to China's large population base, so having the water yield only 2200 cubic metres per capita, about the world is per capita Have the 1/4 of the water yield, be one of 13 countries that water resource is the deficientest per capita in the whole world.Water environment is dirty The problem of dye is extremely serious, and the present situation making China's hydropenia is more serious.The pollution of water environment is the most directly made The about economic development in rural area.The environmental pollution that country sewage causes not only threatens Rural Water seedbed, Also can aggravate the crisis of freshwater resources, make arable land irrigation water can not get effectively and ensure, threaten agriculture The survival and development of the people.2. from the perspective of social background's (national policy), China's Eleventh Five-Year Plan In propose the great historic task of building a New Socialist Countryside, and specify that " production development, life Live rich, rural area civilization, cleanliness of villages, the management people's livelihood " construction object.Domestic sewage in rural areas Process problem is the important content of building Socialist New, is also that Rural Human Settlements improves simultaneously Need the pressing issues solved.Therefore, the improvement being devoted to country sewage pollution is very urgent.

For early established municipal sewage treatment, the process of country sewage is that current environment is controlled The a difficult problem of reason.Municipal sewage can be collected and be delivered to sewage treatment plant and process by urban drainage pipe network, But the process of country sewage can not use for reference method for the treatment of city waste water, China's rural residence dispersion, rural area Drainage pipeline cannot UNICOM, i.e. allow to along with main roads extend, investment cost is the highest.
