In order to protect water environment, a large amount of funds are invested in the country for pollution treatment, the construction of urban sewage treatment plants is increased in recent years, and the treatment of urban domestic sewage is comprehensively enhanced. However, because the sewage generated in towns is far away from the sewage treatment plant, the cost of paving pipelines to convey the sewage to the sewage treatment plant is high, and the existing small-sized sewage treatment mode is single, so that the sewage can not be well purified.

The existing urban sewage treatment is mainly carried out by a large sewage treatment plant, and the urban sewage is directly discharged after reaching the standard by the sewage treatment plant. Along with the acceleration of the urban process in China, the living standard of residents is continuously improved, the discharge amount of domestic sewage after reaching standards is huge, and the increment speed of the annual discharge amount is faster and faster. About 80% of the estimated urban tap water supply amount is changed into urban sewage to be discharged into an urban pipe network, and if the urban sewage is collected, 70% of the urban sewage can be reused for urban water, landscape environment water and the like after being subjected to regeneration treatment. In urban construction, road cleaning, fire protection, urban greening water, vehicle flushing, building construction water and the like are all directly used for a long time, so that water resources are wasted, and energy is consumed.

Along with the enhancement of environmental protection and energy saving consciousness of people in the development of society, fresh water resources can be effectively saved after the domestic water is treated to a certain degree, and living expenses can be reduced.

Detailed Description

The method for originally ecologically treating urban domestic sewage is specifically described below with reference to the accompanying drawings.

The original ecological treatment method of urban domestic sewage, which is disclosed by the invention, is shown in figure 1, and comprises the treatment of kitchen water, toilet water and toilet water, and the treatment of water for washing clothes, bathing and foot washing. Wherein:

the invention firstly communicates the kitchen water tank with the toilet water storage tank through the pipeline for treating the kitchen water and the toilet water, so that the waste water in the kitchen water tank flows into the toilet. In order to prevent the oil dirt from blocking the pipeline, loaches are placed in the pipeline, and the loaches can clear the oil dirt in the pipeline when moving, so long as the two ends of the pipeline are blocked, and the smooth flowing water is ensured. A large loach is placed in a water storage tank of the toilet to clean greasy dirt and the like on the inner wall, and a plurality of ventilation holes are drilled on a cover of the water storage tank of the toilet.

The invention is provided with two overflow pipes in the toilet water storage tank, the inner diameter of the two overflow pipes is slightly larger than the inner diameter of a pipeline connected between the kitchen sink and the toilet water storage tank, so that the water flow quantity of the two overflow pipes is larger than the water flow quantity of the pipeline connected between the kitchen sink and the toilet water storage tank, the height of the two overflow pipes is consistent with the height of water when the toilet water storage tank is full of water, and the lower ends of the two overflow pipes are respectively connected with a sewer pipeline of the toilet. Therefore, the phenomenon that water overflows from the water storage tank after the water storage tank of the toilet is full of water can be effectively avoided, and the phenomenon that loaches placed in the water storage tank of the toilet run off can be effectively avoided.

The technology can be used for building a large biogas tank for a plurality of wheels, and can be used as the input of fuel manufacturing and the input of organic fertilizer production, and the technology can be duplicated infinitely, and plant leaf stems in communities or units and the like are crushed and then added into the large biogas tank to generate biogas for cooking bowls, chopsticks, dishes and the like, so that the detergent is not needed. The clarified water in the biogas production process is stored in a safety big pool built beside, and plants in towns are watered by adding rainwater, and the whole year round. The biogas residue liquid is conveyed to farmlands or forest lands in suburbs by a high-pressure pump through a pipeline and then is buried, so that most of water in the biogas residue liquid is evaporated or absorbed and decomposed by plants and then released into the air as moist air, and forms rain and snow to fall into the land, and water pumped from the ground is water in a well. The circulation is that most of the used sewage is changed into clean water for reuse.

The method changes waste water into clean water, reduces the production of chemical fertilizers, solves the problem of land restoration hardening, reduces a large amount of energy consumption and environmental pollution, reduces a large amount of sewage in the production process, reduces a large amount of back and forth transportation, and reduces traffic accidents and everything for treating casualties subsequently.

The method uses the money for building the domestic sewage treatment plant to build the engineering, has the advantages of reducing harm to benefit, radically treating sewage, obtaining a large amount of fuel and excellent organic fertilizer, and effectively repairing the hardening problem of the existing soil caused by using chemical fertilizers by using the original ecological organic fertilizer. Due to the high operating costs of sewage treatment plants, some sewage treatment plants can only be checked to switch on the treatment system, usually only as a sewage treatment plant through which sewage flows. The method can thoroughly treat sewage and generate huge ecological and economic benefits, and the method is a perfect original ecological system engineering for treating urban domestic sewage and can change sewage into clean drinking water in a way of magical words.

The invention relates to a method for treating water for a toilet, washing clothes, bathing and washing feet, which comprises the steps of building a safe sedimentation tank for a part of money of a sewage treatment plant in a plurality of units of a space below a building or households in a district, wherein one end of the bottom of the sedimentation tank is high, the other end of the bottom of the sedimentation tank is low, and the interior of the sedimentation tank is divided into three adjacent small tanks for three layers of clarified water. Grooves are respectively arranged at lower parts of the bottoms of the small tanks, so that one end of each small tank is provided with a groove so as to suck and suck sediment, and the sediment contained in the grooves is used as a raw material of pesticides. The water in the toilet and the bath water in the washing water and the foot washing water are concentrated into another set of pipelines and flow into a small pool with high bottom of the sedimentation tank, namely a first small pool, sewage enters from one corner of one small pool, and enters into the next adjacent small pool from the other corner opposite to the small pool, so that the water is clarified to the greatest extent.

The water pumped from the third small pool is the clearest water, the water is pumped to a durable water tank to be installed on the roof through a water supply pipe by a water pump, the middle of the bottom of the water tank is low so as to suck the clarified sediment again, and fire-extinguishing water taps are installed on each layer and the roof along the water supply pipe for fire extinguishment. The water flowing into the durable water tank is evaporated into the air by sun and wind blowing, and under the action of high-altitude wind force, a part of moist air moistens trees and other plants, so that a plurality of water tanks on the roof can find water pits of urban and rural areas 60 years ago. When the moist air returns to the earth, it is pumped up the well for use. In order to ensure that water in the durable water vat is not washed away by rainwater when raining, firm metal hooks are arranged on the parapet wall and the gabion wall when the durable water vat is installed, a plurality of water vats can be covered with durable material cloth at one time when raining is about to occur, and the material cloth is fixed on the metal hooks. If the water in the durable water vat of the sudden heavy rain flows out to the lower floor through the downpipe, a plurality of small soil pits which are specially dug on the edges of the big trees and are connected with the big trees are arranged on the lower floor, aquatic plants are grown in the small soil pits, the water stored in the water pits is absorbed and decomposed into moist air by the big trees beside the water pits, the big trees are suitable for growing in any region of the country, and then the moist air is changed into rain or snow to return to the earth, so that the water in the well is changed.

The invention can also be applied to the treatment of domestic and working sewage of each unit, can also be applied to planned vast rural areas, or can be applied to some places through transformation. The invention can be used in any region of the whole country.
