Abstract
The technological process of treating domestic sewage for reuse includes the following steps: pre-treatment through adding strong oxidant in pre-treating pond, coagulation and reaction under stirring, and deposition in deposition pond for 1-2 hr; conventional physical and chemical purification; and secondary sterilizing treatment. The said process can degrade organic pollutant in domestic sewage efficiency, eliminate harmful and toxic matters and bacteria, and eliminate carcinogenic and mutagenic matters, and the treated water may be reused. The present invention is especially suitable for purifying water from swimming pool, bath room, etc.
Description
Technical field
The present invention relates to a kind of sewage purification regeneration device, belong to technical field of sewage.
Background technology
The mankind use precipitation, filtration, technology as centralized water treatment plant the earliest from Englishman in 1804, the American had invented coagulation, precipitation, filtration, chlorine disinfectant technology in 1884, use the history in 120 years till today, though the mankind constantly have new discovery and raising aspect clean water treatment, but the treatment process of domestic water but remains unchanged basically, does not upgrade in essence and breaks through.Yet very big variation has but taken place at the water source of process object: the water source before century-old is because industrial, agriculture undeveloped, and water body is not contaminated.And in decades, development, the especially chemical engineering industry of modernization industry are advanced by leaps and bounds, industrial wastewater discharge, the loss of agrochemical, agricultural chemicals, the pollution of sanitary sewage etc., serious day by day to the contaminated degree of source water, make the traditional water treatment process be difficult to guarantee fine water.Not only can't remove a large amount of solvability organic pollutants in the water, and in chlorination process, also will generate the organic chloride very big human health damage, as: chloroform, chlorophenol, chlorobenzene, strong carcinogen and mutagenic matters such as haloform.Yet the traditional water treatment process that the past sets up at the cleaning water source, the water treatment requirement at the current contaminated water source of incompatibility, reach contaminated water source water security and effectively handle, guarantee the water quality of domestic water, the novel water purification process system that must adapt with it.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of effective removal, degraded organic pollutant and, toxic substance harmful to HUMAN HEALTH and the bacterium in the sanitary sewage is provided; Can all remove carcinogenic substance and the mutagenic matter that is produced in the cholorination process, and the water purification rate after water conditioning, the purification is reached more than 90%, can purify repeatedly, reuse does not repeatedly have the dirty technology for purifying life waste water for generation and reusing that discharges.
The present invention finishes by following technical measures.
The present invention includes following steps:
1, pretreatment technology enters pretreatment pool with sewage, according to the contained composition of sewage, adds strong oxidizer in the 1mg/L-8mg/L ratio, by stirring abundant coagulation, reaction, enters the settling tank that links to each other with pretreatment pool again, carries out 1-2 hour precipitation;
2, physico-chemical purification treatment process, oettIed sewage carry out conventional physico-chemical purification treatment process, and its processing condition are identical with the common process condition;
3, the water purification re-sterilise is disinfected, and will enter water purifying tank again by the water purification behind the physico-chemical purification treatment process, carries out sterilization, sterilization by ozone machine or electronic mycocidal device.
Described strong oxidizer is a potassium permanganate.
The present invention adds pretreatment technology and the water purification re-sterilise is disinfected technology on existing physico-chemical purification treatment process basis, its effect is, by pretreatment technology, add strong oxidizer, the molecular structure of effectively removal, degraded and destruction organic pollutant; Pass through the physico-chemical purification treatment process again, behind the acquisition water purification, enter the water purification re-sterilise and disinfect, make water quality reach country-level standard.
The present invention is through after the potassium permanganate pre-treatment, and test shows no matter pH value is lower molecular weight, lower boiling organic pollutant under neutrallty condition, or high molecular, high boiling point organic pollutant, and the clearance of potassium permanganate is all very high.About organic pollutant more than 50% can all be removed, and all the other major parts are all more than 85%.Because in oxidising process and the hydrated manganese dioxide that produces has the effect of the molecular structure of removal, degraded and destruction organic pollutant, so re-sterilise, sterilization can not form carcinogenic, mutagenic matter.Through the running repeatedly of small-sized model machine, effluent quality detects through economizing quarantine station, and the domestic water index has reached the hygienic standard of national regulation, stable effluent quality.Water purification rate after the purification reaches more than 90%, can purify repeatedly, and reuse repeatedly, significantly water saving is saved water rate more than 90%, does not have dirty discharging, the protection environment.The present invention is specially adapted to the sewage purification and reuse of swimming pool water purification, restaurant, hotel, bathing pool etc.
Embodiment
Embodiment 1: step of the present invention is as follows, one, to entering the denseer sewage of suspended substance such as various greases of containing of pretreatment pool, washing composition, at first pH value is transferred to neutrality, add potassium permanganate in the 8mg/L ratio again, by stirring abundant coagulation, fully reaction enters the settling tank that links to each other with pretreatment pool again, precipitates 1.2 hours.Two, to oettIed sewage, carry out conventional physico-chemical purification treatment process, its processing condition are identical with the common process condition; Promptly, send into reaction tank by transfer roller, add flocculation agent by chemicals dosing plant, and, make it in the pond, to form flco by under meter control dose, carry out water, the dirty separation by the high pressure air-floating apparatus, through slag scraper suspended impurity is removed outside the pond, sent into pressure filter, the moisture backflow pretreatment pool of extrusion by pipeline, dried slag is as refuse treatment, and the water purification behind the separating suspended substances obtains water purification again after dark purification, filtration, absorption.Three, after water purification flows into water purifying tank, use ozone machine to carry out re-sterilise, sterilization, thereby obtain to meet the water purification of state-set standard.
Embodiment 2: step is as follows, one, contains the denseer sewage of suspended substance such as agricultural chemicals to what enter pretreatment pool, at first pH value is transferred to neutrality, add potassium permanganate in the 4mg/L ratio again, by stirring abundant coagulation, fully reaction enters the settling tank that links to each other with pretreatment pool again, precipitate 1 hour, adopt ozone machine to carry out re-sterilise, sterilization.Other technologies are identical with embodiment 1.
Embodiment 3: step is as follows, one, the bath water that enters pretreatment pool is contained the lighter sewage of suspended substance such as washing composition, at first pH value is transferred to neutrality, add potassium permanganate in the 2mg/L ratio again, by stirring abundant coagulation, fully reaction enters the settling tank that links to each other with pretreatment pool again, precipitate 1 hour, carry out re-sterilise, sterilization by the electronic mycocidal device.Other technologies are identical with embodiment 1.
