Besides, the technique of the present invention has obvious superiority in the aspects of technology and economy and has a high practical value.
Description
Technical field:
The present invention relates to a kind of physical chemistry treatment process of bath wastewater, can effectively remove most pollutents in the bath wastewater by this method, and make it reach the multiplexing water quality standard of bathing.
Background technology:
Because the constant tension of water resources, the utilization ratio that how to improve existing water resources has become a big research topic of water treatment field.Bathing already is city water consumption rich and influential family, one medium scale bathing pool day water loss can reach hundreds of tons.With Harbin is example, and press 600,000 people's bathings every day in the whole city's 9,500,000 populations, and on average everyone bath water amount is with 0.2m
3Calculate the then daily bathing water yield 120,000 m
3, a year water consumption reaches 0.44 hundred million m
3Labour intensity height, the stream of peoples such as industrial enterprise such as factory, colliery and hotel account for more than 30% of domestic consumption especially than many places bath water amount, and this explanation bathing is already through becoming the important consumption place of municipal water supply.Domestic each big city is considered for water saving, has generally been improved the bath water water price.As Harbin City's 2003 new water prices with bathing industry water by 5 yuan existing/m
3Bring up to 10 yuan/m
3, high water price policy will guide bathing already to manage water saving, and improves the repeating utilization factor of water.According to investigations, a kind of safe and reliable multiplexing process technology is wished to have in the bathing place more than 90%.For general sanitary sewage, the bath wastewater pollution level is lighter.With its processing and carry out reuse on the spot and not only can open up " new water source " for bathing enterprise, alleviate bathing business economic pressure, can also reduce pollution to water surrounding.China is to be conceived to water reuse in the conduct to the research majority of bath wastewater recycling processing technique and equipment at present, direct multiplexing improvement lacks systematic research to bath wastewater, also less to every contamination index in the water quality characteristics of bath wastewater, particularly waste water to the influence research of each process procedure.
Summary of the invention:
For the waste water that makes bathing can be recycled again, the invention provides a kind of treatment process to bath wastewater.Technical scheme of the present invention is as follows: the integrated physical chemistry treatment process that a kind of bath wastewater is multiplexing, and it is finished by following step: (one) drops into poly-ferric chloride in waste water, carries out coagulating sedimentation; (2) water of post precipitation filters by hard coal-quartz sand double-layer filter material; (3) water after filtering enters in the container of splendid attire granular carbon adsorption column and zeolite ion exchange column and carries out charcoal absorption and ion-exchange; (4) water after handling enters ultra-filtration membrane and filters; (5) water is carried out disinfection by ultraviolet light.In precipitation process of coagulation, the ratio of adding is 18～22 milligrams of poly-ferric chlorides of every liter of waste water, and sedimentation time is 10～17 minutes; Particle diameter is that the hard coal (1) that 0.9～1.2 millimeter quartz sand (2) and particle diameter are 1.5～2 millimeters is formed hard coal-quartz sand double-layer filter material in step (two), and the water of post precipitation passes through filtrate with 10～15 meters/hour filtering velocity.Present method is divided into four major parts: pretreatment unit, absorbing unit, film unit and uv sterilisation unit.Wherein pretreatment unit (comprising coagulating sedimentation and hard coal-quartz sand sand filtration) is mainly removed suspended substance, dregs and partial organic substances, for later unit link reduces load, prevents to stop up; Absorbing unit (comprising charcoal absorption and zeolite exchange) is mainly removed dissolved organic matter, is smelt flavor and ammonia nitrogen, and film unit is further removed small amounts of contamination and bacterium, plays the water quality effect of checking on; Uv sterilisation mainly is the deactivation residual virus, improves the reliability of hygiology index.The outstanding feature of this technology: the one, from the cell processing angle, a whole set of technology is made up of processing unit independently at bath wastewater water quality, organically combines, and compact and reasonable is convenient to maintenance management; The 2nd, emphasized hygienic reliability, it is the bacteriology index, experimental result proves, adopt ultra-filtration technique can remove bacterium more than 99.5% and 100% intestinal bacteria, uviolizing is placed on the last of technology, further kill remaining bacterium and all viral, the two has stopped pathogenic bacterium and the propagation of virus between the bathing personnel in conjunction with making multiplexing water hygiene index be lower than the tap water prescribed value.The sterilization method that present method adopts does not add chemical agent, does not produce secondary pollution and to the influential toxic substance of human health, sterilization speed is fast, and efficient height and operation of equipment are simple; The 3rd, running cost is low, with day output 100m
3Meter, the molding device wastewater recycle rate is 80～85%, reuse bath wastewater all charges per ton (containing medicament, power consumption, equipment amortization etc.) is 2.13 yuan,, is accepted by the bathing industry easily as the tap water price of commercial water far below at present.Therefore this technology is with the obvious advantage in technology and economic aspect, has very high practical value.
