Abstract
The invention discloses a domestic sewage purification process. The domestic sewage purification process comprises the following steps: building a catch basin and a coarse screen, arranging a fine screen and a grit chamber, performing sludge treatment, enabling sewage passing through the grit chamber to enter a biochemical pool and then a membrane separation pool, utilizing the magnetic field force for interception, selecting disinfection by ultraviolet light and water treatment by ozone, adopting activated carbon adsorption and the ion-exchange method for water softening, and filling a recycling bin with the treated water. The domestic sewage purification process ensures that after domestic sewage and industrial waste water treatment, domestic sewage reaches the purified water standard and can be recycled, so that sustainable development of water resources is realized. Meanwhile, the domestic sewage purification process is economical and reasonable and is an effective water treatment process method.
Description
Technical field
The present invention relates to environmental purification field, particularly relate to one way of life sewage purification process.
Background technology
Along with China's Economic development, city and country water consumption is in continuous increase, China's serious water shortage, per capita water resources occupy the just world per capita 1/4th, quantity of wastewater effluent is also in continuous increase simultaneously, sanitary sewage discharge affects the health of the public, hinder sustainable economic development, so sewage purification is necessary, simultaneously, recycling after sewage purification, shortage of water resources contradiction can be alleviated, recycle is formed to water resources simultaneously, it is the important step of human kind sustainable development, therefore sewage purification, it is the problem that China needs to solve at present that sewage reclaims, simultaneously, the sewage disposal of China is only used extensively in city and small towns, village level unit does not build waterworks and sewage work, make village sewage directly discharged to river, contaminate environment, so the self-built sewage purification in each village and each factory, realize water cycle necessary.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one way of life sewage purification process, can make purifying domestic sewage, thus water resources is reused, and realizes Sustainable Water Resources Development, simultaneously with low cost, meets village level and the use of factory level unit.
Described one way of life sewage purification process, comprises the steps:
The first step, build Vatch basin, washing sanitary sewage, lavatory sewage by pipe influx to Vatch basin.
Second step, builds coarse rack, and arrange screen cloth on coarse rack, removes suspended matter, large bits are filtered by coarse rack, can be used as fertilizer as the recovery of fertilizer.
A kind of optimal technical scheme, in described one way of life sewage purification process second step, the screen cloth of employing is 120 ~ 150 order stainless steel sift net filtrations, removes suspended substance in water, comprises plankton, the broken bait of residue etc.
3rd step, arranges fine fack and settling pit, by sump pump wastewater streams through fine fack to settling pit, inorganic particle larger for proportion in sewage is precipitated and gets rid of.
A kind of optimal technical scheme, described settling pit adopts advection dirt sand pond, adopts grit water separator that waste water is separated.
4th step: sludge treatment, the mud in Vatch basin at set intervals regularly sludge condensation, carries out sludge dewatering simultaneously.
5th step: the sewage through settling pit enters into biochemistry pool, carries out denitrification to biochemistry pool, dephosphorization process, desulfurization process.
6th step: sewage enters membrane sepn pond through the process of biochemistry pool, use membrane separating method, impurity concentrates, and is separated.
7th step, utilizes magnetic field force to retain, and removes magnetic and nonmagnetic heavy metal ion in waste water, makes magnetic ion be subject to magnetic field suction, caught by magnetic field.
8th step: select ultraviolet disinfector.
A kind of optimal technical scheme, described ultraviolet disinfector adopts several groups of high-intensity ultraviolet germicidal tubes, and water body fully contacts with fluorescent tube, thus improves disinfecting power.
9th step: ozone water process, effluent stream through pipeline, increase ozone equipment for treating water, device comprises ozone decomposed device, ozone dissolver and ozone pressurizing device
Tenth step: adopt charcoal absorption, the impurity in further planar water.
11 step: adopt ion exchange method water softening.
12 step: load recycling bin, sensor assembly is set in described recycling bin.
Described sensor assembly is used for monitoring the temperature of water, the oxygen level of water, the pH value of water, the oxygen dissolved of water, and sensor is connected with microprocessor by control module, and microprocessor is arranged in monitored base stations, while monitoring record anatomical connectivity is outputted to display instrument.
The invention has the beneficial effects as follows: one way of life sewage purification process of the present invention, after making sanitary sewage and Industrial Wastewater Treatment, sanitary sewage reaches water purification standard, can recycle, makes Sustainable Water Resources Development.Economical rationality is simultaneously a kind of effective water treatment process method.
