Description

Reclaimed water recycling water treatment system

Technical Field

The utility model relates to a sewage normal water recovery water treatment technical field of recycling such as rainwater, shower, wash, laundry, dense water, air conditioner condensation, surface water, kitchen, lavatory especially relates to a normal water recovery water processing system.

Background

The term "reclaimed water" in reclaimed water recycling is relative to the terms of upper water (feed water) and lower water (drainage). The reclaimed water reuse technology is that after the domestic waste water (bath, washing, clothes washing, kitchen and toilet) of residential area is treated in a centralized way, the reclaimed water can be reused for greening irrigation, vehicle flushing, road flushing, household toilet flushing and the like of residential area according to a certain standard, thereby achieving the purpose of saving water.

Three treatment modes of reclaimed water are available according to different purposes

1. One is that the water is treated to the standard of drinking water and directly reused in daily life, namely the direct cyclic utilization of water resources is realized, and the treatment mode is suitable for areas with extremely-short water resources, but the investment is high and the process is complex;

2. the other is the standard of treating the water into non-drinking water, and is mainly used for water which is not in direct contact with human bodies, such as flushing of toilet bowls, cleaning of ground and automobiles, greening watering, fire fighting, industrial common water and the like, which are common reclaimed water treatment modes.

3. The industrial sewage reaching the discharge standard can be reprocessed by utilizing a reclaimed water recycling technology in industry, and equipment such as a softener, RO, EDI/mixed bed and the like is generally added to ensure that the industrial sewage reaches the levels of softened water, purified water and ultrapure water, so that the industrial sewage can be recycled, and the purposes of saving capital and protecting environment are achieved.

The reclaimed water treatment process is generally divided into 3 types according to the treatment method:

1. physical treatment method:

the membrane filtration method is suitable for the condition of large water quality change.

The process is characterized in that: the device is compact, easy to operate, and less affected by load variations.

The membrane filtration method is that under the action of external force, the separated solution flows along the surface of a filter membrane at a certain flow rate, and the solvent, low molecular weight substances and inorganic ions in the solution permeate the filter membrane from the high-pressure side to enter the low-pressure side and are discharged as filtrate; and high molecular substances, colloidal particles, microorganisms and the like in the solution are intercepted by the ultrafiltration membrane, and the solution is concentrated and discharged in a concentrated form.

A heat evaporation method: is suitable for any water quality.

The process is characterized in that: high stability, easy maintenance, long service life, simple operation and no influence on the operation of the equipment due to water quality fluctuation.

The evaporation heating method is to separate pure water and salt solid under the condition that the solution reaches the boiling point in an evaporation body by heating evaporation, the pure water is condensed into pure water in a steam form, and the concentrated solution is continuously circulated and evaporated to form the salt solid. The pure water quality can achieve the purpose of reclaimed water recycling through a series of measures such as filtration and the like.

2. A physical and chemical method:

is suitable for the condition of large change of the sewage quality. The methods generally adopted are: sand filtration, activated carbon adsorption, flotation, coagulating sedimentation and the like. The process is characterized in that: the hollow fiber ultrafilter is adopted for processing, the technology is advanced, the structure is compact, the occupied area is small, the system runs intermittently, and the management is simple.

3. Biological treatment method

Is suitable for sewage with high organic matter content. Generally, biological treatment methods such as an activated sludge method, a contact oxidation method (as shown in the figure), a biological rotating disk and the like are adopted. Or used alone or in combination with several biological treatment methods, such as contact oxidation plus biological filter; biological filter and active carbon adsorption; and (5) rotating disc sand filtration and other processes. The process has the advantages of strong capability of adapting to hydraulic load change, less sludge generation amount, easy maintenance and management and the like.
