Intermittent type formula effluent treatment plant

Technical Field

The utility model relates to an intermittent wastewater treatment device, which belongs to the technical field of water treatment.

Background

In industrial wastewater such as domestic sewage, food processing and paper making, organic substances such as carbohydrates, proteins, oils and fats, lignin and the like are contained. These substances are present in the sewage in a suspended or dissolved state and can be decomposed by biochemical action of microorganisms. Oxygen is consumed in its decomposition process and is therefore referred to as an oxygen-consuming contaminant. Such contaminants can cause a reduction in dissolved oxygen in the water, affecting the growth of fish and other aquatic organisms. After the dissolved oxygen in water is exhausted, the organic matter is anaerobically decomposed to generate bad smells such as hydrogen sulfide, ammonia and mercaptan, which deteriorate the water quality. The organic matter components in the water body are very complex, and the concentration of the oxygen-consuming organic matter is usually expressed by the oxygen consumption in the biochemical decomposition process of the oxygen-consuming substance in unit volume of water.

The high-concentration organic wastewater generally refers to wastewater with COD of more than 2000mg/L discharged by industries such as papermaking, leather, food and the like. They can be generally classified into three categories according to their nature and origin: (1) generally, the organic wastewater is industrial wastewater which takes agricultural and pastoral products as raw materials, such as food industrial wastewater; (2) high-concentration organic wastewater containing harmful substances and being easily biodegradable, which is mainly from light industry, metallurgical industry and the like, such as pharmaceutical industry wastewater; (3) high-concentration organic wastewater which contains harmful substances and is difficult to biodegrade is mainly from organic synthetic chemical industry, pesticide production industry and the like, such as pesticide wastewater. The pollutant components in the high-concentration organic wastewater are complex, and the high-concentration organic wastewater poses serious threats to human health and ecological environment after being discharged into a human water body.

The high-concentration organic wastewater mainly has the following characteristics: (1) the concentration of organic matters is high. The COD is generally above 2000mg/L, some of the COD is even as high as tens of thousands to hundreds of thousands mg/L, the BOD is lower, and the biodegradability of a lot of waste water is poor; (2) the composition is complex. The waste water often contains production raw materials, side reaction products and various inorganic salts, and the waste water also contains heavy metals and toxic organic matters; (3) high color and peculiar smell. Some waste waters give off offensive odors. Causing adverse effects to the surrounding environment; (4) many acids, bases, salts, often have strong acids or strong bases. Due to the biodegradation effect, the high-concentration organic wastewater can lead the receiving water body to lack oxygen, most aquatic organisms die, the water quality and the environment are deteriorated, the use value of the water body is lost, and the normal life of people nearby the water body is seriously influenced. Meanwhile, the high-concentration organic wastewater contains a large amount of toxic organic matters, which can be continuously accumulated and stored in natural environments such as water, soil and the like, and finally enter human bodies to harm human health.

At present, the method for treating organic wastewater at home and abroad mainly comprises three modes, namely a chemical method, a biological method and a physical method. If firewood shakes bright has invented an organic waste water treatment system, it includes the preliminary filtering ponds, the right side of the preliminary filtering ponds has a sedimentation tank, the right side of the sedimentation tank has an organic waste water treatment facility, the preliminary filtering ponds and sedimentation tank and organic waste water treatment facility are connected together through the water pipe, the organic waste water treatment system, insert organic waste water from the inlet tube, in flowing into the drum, flow out from the standpipe, utilize the impact force of organic waste water to drive the rotation of the round bar one, the rotation of the round bar one drives the rotation of the bull bar, the rotation of the bull bar drives the rotation of the montant one, the rotation of the montant one drives the rotation of the round bar one, thus can be reciprocating to strike the round bar two, thus make the whole filter plate vibrate, through this way not only can prevent effectively that the filter plate is blocked by the impurity in the organic waste water, the preliminary filtration rate can also be increased. Although the device has low energy consumption, the device can tightly filter the organic wastewater, can not degrade soluble organic matters and needs to further treat the wastewater subsequently.

The invention discloses a high-concentration organic wastewater treatment device (a high-concentration organic wastewater treatment device) which is a container with an inlet and an outlet, wherein the inlet is a pipe body for introducing high-concentration organic wastewater, the outlet is a pipe body for discharging treated liquid, a partition plate is arranged in the container, a containing cavity of the container is sequentially divided into a pretreatment unit, an anaerobic treatment unit, a secondary aerobic treatment unit, a biological denitrification filter and a precipitation unit by the partition plate, and the four units can be communicated with each other to form an integrated high-concentration organic wastewater treatment channel. The utility model discloses an in solving high concentration organic wastewater treatment engineering, using advanced treatment process and operational mode, integrated device can set up in the factory in a flexible way, also can realize burying the processing system of formula entirely, does not occupy mill's ground, has solved the dual good effect of advantage of high concentration organic wastewater emission problem and saving land for the blowdown enterprise. But the device can only be used for easily biodegrading organic wastewater, and can be used for wastewater which can degrade organic matters but contains harmful substances; and non-biodegradable and harmful organic waste water are not suitable.

The invention discloses high-concentration nonbiodegradable organic wastewater treatment equipment and a method, wherein the high-concentration nonbiodegradable organic wastewater treatment equipment comprises a first cathode electrolytic cell, a second cathode electrolytic cell, an anode electrolytic cell and a sedimentation tank which are sequentially communicated, the second cathode electrolytic cell is communicated with the first cathode electrolytic cell through a wastewater reflux pump to form a circulation loop, and a first cathode plate and an aeration device are arranged in the first cathode electrolytic cell; a second cathode plate is arranged in the second cathode electrolytic tank; an anode plate is arranged in the anode electrolytic tank; the first cathode plate, the second cathode plate and the anode plate are all active carbon fiber electrode plates and are all communicated with the same direct current power supply. The technical scheme provided by the invention aims to solve the problem that the existing organic wastewater treatment method has poor treatment effect on high-concentration organic wastewater difficult to biodegrade. The method has good treatment effect, high speed, treatment effect on various organic wastewater, obvious defects, high energy consumption, generation of a certain amount of hydrogen and oxygen in the electrolysis process and high danger coefficient.

The chemical method mainly aims at treating the waste water containing harmful substances and the organic waste water which is difficult to biodegrade and harmful, wherein the organic substances can be degraded. The chemical treatment technology for treating high-concentration organic waste water is a method for converting pollutant components in the waste water into harmless substances by applying a chemical principle and a chemical action so as to purify the waste water. Chemical oxidation processes fall into two broad categories: one is to oxidize organic matters in the wastewater into carbon dioxide and water by using strong oxidants (such as hydrogen peroxide, potassium permanganate, hypochlorite, ozone and the like) at normal temperature and normal pressure; the other is to decompose organic matters in the wastewater at high temperature and high pressure, including supercritical water oxidation and wet air oxidation processes, wherein the used oxidant is usually oxygen or hydrogen peroxide, and a catalyst is generally adopted to reduce the reaction conditions and accelerate the reaction rate. The chemical oxidation method has the advantages of high reaction speed and simple control, and is more and more favored by researchers.

Persulfate (PS) is a strong oxidant, is easily dissolved in water to generate persulfate ions with strong oxidizing property, and can not efficiently degrade organic pollutants at normal temperature due to stable property, so that activated persulfate radicals can generate sulfate radicals with stronger oxidizing property by a photoactivation method, a thermal activation method, a metal activation method and other methods, a large number of sulfate radicals and organic matters which are difficult to degrade in water generate a series of redox chemical reactions, and the decomposition and mineralization of the organic pollutants which are difficult to degrade in industrial wastewater are realized. The sulfate radical redox potential (2.5-3.1V) is higher than that of hydroxyl radical (. OH) (1.9-2.7V), the stability and the half-life period are longer, and the method can efficiently oxidize and degrade common organic pollutants in production and life, and is a new direction for innovation and research of advanced oxidation technology. The persulfate activation technology is favored in the treatment of water pollutants due to the characteristics of high efficiency, short time consumption and low secondary pollution of the treatment.
