設(shè)備工藝
根據(jù)現(xiàn)有的水質(zhì)水量，目前對于污水處理工藝一般有以下幾種：
1、 物化處理
物化法常作為一種預(yù)處理的方法應(yīng)用于污水處理，預(yù)處理的目的是通過回收廢水中的有用成分，或?qū)σ恍╇y生物降解物進行處理，從而達到去除有機物，提高生化性，降低生化處理負(fù)荷，提高處理效率。一般常用的物化法有絮凝沉淀（氣?。⑽椒ǖ?。
1) 絮凝沉淀
廢水中含有膠體、酯類及懸浮物，使廢水呈高分散系膠體溶液，這種膠體一般較穩(wěn)定，治理這類廢水首先要破壞其膠體狀態(tài)。化學(xué)絮凝法正是通過藥劑的物理化學(xué)作用，破壞廢水膠體，使分散狀態(tài)有機物脫穩(wěn)、凝聚，形成聚集狀態(tài)粗顆粒物質(zhì)從水中分離而出。
在廢水處理研究中，絮凝沉淀法因其可有效降低廢水濁度和色度，能去除多種高分子有機物而被廣泛采用。近年來，絮凝劑開發(fā)從傳統(tǒng)無機絮凝劑發(fā)展到無機高分子，有機高分子絮凝劑，目前正在進一步探討微生物絮凝劑。
2) 吸附法
吸附劑的種類很多，有活性炭、大孔樹脂、活性白土、硅藻土等。在有機廢水中常用的吸附劑有活性炭和大孔樹脂。雖然活性炭具有較高的吸附性，但由于再生困難、費用高而在國內(nèi)較少使用。
2、 化學(xué)處理
化學(xué)氧化法分為兩大類,一類是在常溫常壓下利用強氧化劑(如過氧化氫、*、次氯酸鹽、臭氧等) 將廢水中的有機物氧化成二氧化碳和水;另一類是在高溫高壓下分解廢水中有機物,包括超臨界水氧化和濕空氣氧化工藝,所用的氧化劑通常為氧氣或過氧化氫,一般采用催化劑降低反應(yīng)條件,加快反應(yīng)速率。
化學(xué)氧化法反應(yīng)速度快、控制簡單,但成本較高,通常難以將難降解的有機物一步氧化到無機物質(zhì),而且目前對中間產(chǎn)物的控制的研究較少。該技術(shù)也常常作為生化處理的預(yù)處理方法使用。 其主要的方法有：
化學(xué)氧化法反應(yīng)速度快、控制簡單,但成本較高,通常難以將難降解的有機物一步氧化到無機物質(zhì),而且目前對中間產(chǎn)物的控制的研究較少。該技術(shù)也常常作為生化處理的預(yù)處理方法使用。 其主要的方法有：
1) Fenton 氧化法
Fenton 試劑具有很強的氧化能力，因此Fenton 氧化法在處理廢水有機物過程中發(fā)揮了巨大的作用。但由于體系中含有大量的Fe2 + 離子，H2O2 的利用率不高,使有機物降解不*。
2) 臭氧氧化法
臭氧在水處理方面具有氧化能力強,反應(yīng)速度快,不產(chǎn)生污泥,無二次污染等特點,在去除合成洗滌劑以及降低水中的BOD、COD 等方面都具有特殊的效果。臭氧對難降解有機物的氧化通常是使其環(huán)狀分子的部分環(huán)或長鏈分子部分?jǐn)嗔?從而使大分子物質(zhì)變成小分子物質(zhì),生成易于生化降解的物質(zhì),提高廢水的可生化性。
3) 電化學(xué)氧化法
電化學(xué)氧化又稱電化學(xué)燃燒,它是在電極表面的電氧化作用下或由電場作用而產(chǎn)生的自由基作用下使有機物氧化。電化學(xué)氧化分為直接電化學(xué)氧化和間接電化學(xué)氧化。直接電化學(xué)氧化是使難降解有機物在電極表面發(fā)生氧化還原反應(yīng)。
3、 生物處理技術(shù)
生物處理技術(shù)是一般有機廢水處理系統(tǒng)中最重要的過程之一，是利用微生物，主要是細(xì)菌的代謝作用，氧化、分解、吸附廢水中可溶性的有機物及部分不溶性有機物，并使其轉(zhuǎn)化為無害的穩(wěn)定物質(zhì)從而使水得到凈化的技術(shù)。在現(xiàn)代的生物技術(shù)處理過程中，主要有好氧生物氧化、兼氧生物降解及厭氧消化降解這三類，生物處理技術(shù)由于經(jīng)濟可行、無二次污染等特點，已越來越引起重視。
長期以來好氧生物處理技術(shù)，尤其是活性污泥法一直是我國污水處理的主體工藝，它具有處理效率高、出水水質(zhì)好的特點，但它也存在能耗高、運行費用大、剩余污泥產(chǎn)量多等缺點。厭氧生物處理技術(shù)因其具有能耗低、污泥產(chǎn)量少的特點，廢水厭氧生物處理是環(huán)境工程與能源工程中的一項重要技術(shù)，是有機廢水強有力的處理方法之一。雖然厭氧處理有一些優(yōu)點，但是厭氧出水很難直接達到排放標(biāo)準(zhǔn)，一般用于高濃度有機污水的前段生物處理，因此后段生物處理仍然必須通過好氧處理才能達到排放標(biāo)準(zhǔn)。
處理工藝選擇
綜合上述處理介紹，對于生活污水處理工藝優(yōu)先選擇生物處理技術(shù)為主要處理工藝，主要原因是生物處理工藝運行費用省，處理效果好。

Process equipment
According to the existing water quality and quantity, there are generally the following sewage treatment processes:
1. Materialized treatment
Physicochemical method is often used in sewage treatment as a pretreatment method. The purpose of pretreatment is to remove organic matter, improve biochemical properties, reduce biochemical treatment load and improve treatment efficiency by recycling useful components in wastewater or treating some refractory biodegradable substances. The commonly used physical and chemical methods include flocculation precipitation (air floatation), adsorption, etc.
1) flocculation and precipitation
The wastewater contains colloids, esters and suspensions, making the wastewater a highly dispersed colloidal solution, which is generally more stable. The chemical flocculation method is to destroy the colloid of waste water through the physical and chemical action of agents, so that the organic matter in the dispersed state can be de-stabilized and condensed, and the coarse particulate matter in the aggregation state can be separated from the water.
Flocculation sedimentation is widely used in wastewater treatment because it can effectively reduce the turbidity and chromaticity of wastewater and can remove a variety of macromolecular organics. In recent years, the development of flocculants has changed from traditional inorganic flocculants to inorganic and organic polymer flocculants.
2) adsorption method
There are many kinds of adsorbents, such as activated carbon, macroporous resin, activated clay, diatomite and so on. The adsorbents commonly used in organic wastewater are activated carbon and macroporous resin. Although activated carbon has a high adsorption, but because of difficult regeneration, high cost and less use in China.
2. Chemical treatment
Chemical oxidation method is divided into two categories, one is under normal temperature and pressure using strong oxidants (such as hydrogen peroxide, potassium permanganate, hypochlorite, ozone, etc.) in the wastewater of organic oxidation into carbon dioxide and water; The other is the decomposition of organic matter in wastewater under high temperature and pressure, including the process of supercritical water oxidation and wet air oxidation. The oxidant used is usually oxygen or hydrogen peroxide. Generally, the catalyst is used to reduce the reaction condition and speed up the reaction rate.
Chemical oxidation reaction is fast and easy to control, but the cost is high, it is usually difficult to decompose difficult organic matter into inorganic matter in a single step, and the control of intermediate products is rarely studied. The technique is also often used as a pretreatment method for biochemical treatment. The main methods are:
1) Fenton oxidation method
Fenton reagent has a strong oxidation ability, so Fenton oxidation method plays an important role in the treatment of organic compounds in wastewater. However, because the system contains a large number of Fe2 + ions, the utilization rate of H2O2 is not high, so the organic degradation is not complete.
2) ozone oxidation method
Ozone has strong oxidation ability in water treatment, fast reaction speed, no sludge, no secondary pollution and other characteristics, in the removal of synthetic detergent and reduce BOD, COD and other aspects of water have special effect. The oxidation of refractory organics by ozone usually breaks part of the ring molecules or long chain molecules, so that the macromolecules become small molecules to generate biodegradable substances and improve the biodegradability of wastewater.
3) electrochemical oxidation method
Electrochemical oxidation, also known as electrochemical combustion, oxidizes organic matter under the action of electrooxidation on the electrode surface or free radicals generated by the action of electric field. Electrochemical oxidation is divided into direct electrochemical oxidation and indirect electrochemical oxidation. Direct electrochemical oxidation is a kind of REDOX reaction on the surface of electrode.
3. Biological processing technology
Biological treatment technology is one of the most important processes in the general organic wastewater treatment system. It is a technology that utilizes the metabolism of microorganisms, mainly bacteria, to oxidize, decompose and absorb the soluble organics and some insoluble organics in the wastewater, and converts them into harmless stable substances so as to purify the water. In the process of modern biotechnological treatment, there are mainly three categories: aerobic biooxidation, facultative biodegradation and anaerobic digestion and degradation.
For a long time, aerobic biological treatment technology, especially activated sludge process, has been the main process of sewage treatment in China. It has the characteristics of high treatment efficiency and good effluent quality. Anaerobic biological treatment of wastewater is an important technology in environmental engineering and energy engineering because of its low energy consumption and low sludge yield. Although anaerobic treatment has some advantages, it is difficult for anaerobic effluent to directly meet the discharge standard. Generally, it is used for the biological treatment of high concentration organic sewage in the first stage. Therefore, the biological treatment in the second stage must still go through aerobic treatment to reach the discharge standard.
Treatment selection
Based on the above treatment introduction, biological treatment technology is preferred as the main treatment process for domestic sewage treatment process. The main reason is that the biological treatment process has low operation cost and good treatment effect.
Scope of application
1. Hotels, restaurants, nursing homes and hospitals;
2. Residential communities, villages and market towns;
3. Stations, airports, seaports, docks and ships;
4. Factories, mines, troops, tourist spots and scenic spots;

Installation, use and maintenance
1. Foundation: if WSZ series equipment is placed above the floor, only a concrete floor with the same appearance as the equipment is needed as the foundation. Foundation pressure must be greater than 4T/m2, but also horizontal and flat.
If the equipment is buried below the floor, the elevation of the foundation must be less than or equal to the elevation of the equipment and ensure that there is no rain or water. The foundation is generally plain concrete (whether the reinforcement depends on the local geological conditions).
2. Installation: according to the installation drawing, each box shall be placed in place successively. The position and direction of the box shall not be misplaced.
3. Pour clean water into the equipment to check whether there is leakage in each pipe. If there is no leakage, cover the box with soil until the inspection hole of the equipment and level the ground. Connect the control line of the electric control box with the water pump, connect the electric control box with the power supply, pay attention to the direction of the fan and motor when wiring, must be the same as the direction indicated by the fan.
