Description

Be used for waste water treatment purifier

Technical Field

The invention relates to the field of wastewater treatment, in particular to a wastewater treatment and purification device.

Background

The waste water is a general term of water and runoff rainwater drained in the process of activities of residents. The method comprises the steps of domestic sewage, industrial wastewater and other useless water such as primary rain water flowing into a drainage pipe canal, and generally refers to water which can not be recycled after being treated by a certain technology or can not reach a certain standard after being purified by primary pollution. Along with the increasing urban population, the problem of urban domestic wastewater treatment is increasingly prominent. And the urban environment and the construction thereof are always influenced because of the technical lag, the fund shortage and the great treatment difficulty. If the problems are not solved as soon as possible, the pollution is more serious and the influence is worse as the water consumption is continuously increased along with the advance of urbanization. The domestic sewage is the wastewater discharged by people in daily life activities, the wastewater is mainly polluted by domestic waste and human excrement, and the quantity, the components and the concentration of pollutants are related to the living habits and the water consumption of people. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for the propagation of microorganisms, contains a large amount of bacteria and pathogens, and has a certain hazard from a hygienic viewpoint.

In order to protect the environment, save water resources, and treat waste water and liquid such as domestic sewage and the like to reach the discharge standard before being discharged or recycled, however, the key for determining whether the waste water can become water with the discharge standard or recycled water is a waste water treatment technology, and the waste water treatment is to treat the waste water by using physical, chemical and biological methods, so that the waste water is purified, the pollution is reduced, the waste water is recycled and reused, and the water resources are fully utilized. The existing wastewater purification equipment is mainly divided into industrial and civil wastewater purification equipment, the structure is simple because the treated wastewater amount is small, the requirement on the treatment effect is not strict, the industrial wastewater purification equipment has high requirement on the purification degree because the treated wastewater amount is large, and the corresponding requirement on the purification equipment is also strict because large-area environmental pollution is easily caused if the treatment is not good.

Present waste water treatment has more defect, the method that current waste water often adopted the sediment is deposited the large granule pollutant in the waste water earlier and then is filtered, in precipitation process, the filth can be piled up in the bottom of precipitating the device, current waste water treatment device need clear up waste water treatment device's bottom through artificial means, waste time and energy, furthermore, current waste water treatment device is in the filter process, the filter screen takes place the jam easily, lead to the filter process of waste water not smooth enough, filtration efficiency descends, for this, we propose one kind and be used for waste water treatment purifier.
