Description

Water conservancy and hydropower environmental project sewage purification treatment equipment
Technical field
The present invention relates to sewage treatment field, is especially water conservancy and hydropower environmental project sewage purification treatment equipment.
Background technology
Septic tank is a kind of small-sized sewage treating system, including a pond and septic system.Sewage enter pond when, Bacterium can carry out anaerobic decomposition to dirt, and can reduce solid waste volume, then be discharged after precipitation, water pollution degree It will reduce, earliest septic tank originates from the Europe in 19th century, away from modern history more than 100 years existing.In urban life area The initial purpose for setting septic tank is in order to which product takes fertilizer with the progress of urbanization and the aggravation of environmental pollution, septic tank pair Protection water body plays positive effect.Now, in many big cities in China, septic tank the effect of fertilizer is provided for agricultural production Basic to disappear, septic tank is as one of basic measures of environmental protection.
Sewage water filtration be waste water by filter medium or facility with hole, the suspended matter more than pore-size is trapped, Waste water is set to obtain a degree of purification.Filter medium or facility have grid, sieve, sand, filter cloth, the microporous pipe etc. a variety of.Grid Floating material and solid impurity larger in sewage are mainly retained, is generally located in before processing system or intakes of pumping station, tiltedly puts In foul drainage, to remove grid trapped substance at any time.Sieve is made of the metallic plate or woven wire of eyelet more, mainly To retain the relatively fine suspended matter such as the fiber in waste water, trapped substance can be rinsed with water and recycled.With the hair at full speed of science and technology Exhibition, industrial circle also obtained significantly developing, the remote supermans' it is contemplated that and in the same of industrial development of its development speed When, waste water of the same trade or business is also unavoidable, and industrial wastewater pollutes the environment if directly discharge, this can bring loss, And existing effluent filter price is costly, and service life is shorter, can only obtain some impurity in filter sewage, and industrial Metal material is often entrained with waste water, this can jeopardize filter in filter long-time service, reduce its service life, And if the sewage for being entrained with metal material cannot be filtered out, also there is certain infringement to later stage sewage disposal device, and Also reduce the filter effect of sewage.
Reaction tank is a procedure of sewage disposal, hydrolysis process for treating be it is a kind of between aerobic and Anaerobic Treatment method it Between method, and other process combinations can reduce processing cost improve treatment effeciency.Hydrolysis refers to that organic matter enters microorganism Before cell, in the biochemical reaction of extracellular progress, acidizing hydrolyzation tank Nei Fen Sludge Beds area and clear pelagic division, treatment sewage with And the remaining microorganism MRB films to come off during filter back washing are entered in pond by reactor bottom, and pass through the water distribution with reflecting plate Device is rapidly and evenly mixed with Sludge Bed.
Reaction tank, is the place that microbial cleaning is carried out to sewage, wherein containing substantial amounts of beneficial microbe, can absorb The nuisances such as heavy metal ion, rich nutritive material in sewage so that sewage can become more clean, accelerate sewage purification, From the dirt of pollution sources discharge(It is useless)Water, it is higher because containing the total amount of pollutant or concentration, do not reach discharge standard requirement or be not suitable with ring Border capacity requirement, so that when reducing quality of water environment and functional objective, it is necessary to the place handled by artificial-strengthening, this place It is exactly sewage treatment plant, is also known as Sewage Disposal.
Found through analysis:
(1)Existing grid septic tank has the following disadvantages:First, the time persistently handled sewage is longer;Second, at filtering It is poor to manage effect;Third, the septic tank that cement and brick are built into is not easy to movement and cost is higher;
(2)Existing water quantity and quality regulating reservoir has the following disadvantages:First, homogeneous is less efficient, effect is more undesirable;Its Two, it can not realize that pool inner water position is self-regulated;Third, when equipment breaks down, overall waste water processes are influenced;
(3)Existing hydrolysis acidification reaction tank has the following disadvantages:First, the chemical reaction handling time is grown;Second, sewage disposal Efficiency is low;Third, reacting gas is difficult to discharge;
(4)Existing MRB membrane biological reactions pond has the following disadvantages:First, it cannot be cleaned automatically after treated sewage;It is second, dirty Water treatment efficiency is low;Third, the not up to standard and sewage disposal performance of exhaust gas discharge is weak.
