设备工艺
根据现有的水质水量，目前对于污水处理工艺一般有以下几种：
1、 物化处理
物化法常作为一种预处理的方法应用于污水处理，预处理的目的是通过回收废水中的有用成分，或对一些难生物降解物进行处理，从而达到去除有机物，提高生化性，降低生化处理负荷，提高处理效率。一般常用的物化法有絮凝沉淀（气浮）、吸附法等。
1) 絮凝沉淀
废水中含有胶体、酯类及悬浮物，使废水呈高分散系胶体溶液，这种胶体一般较稳定，治理这类废水首先要破坏其胶体状态。化学絮凝法正是通过药剂的物理化学作用，破坏废水胶体，使分散状态有机物脱稳、凝聚，形成聚集状态粗颗粒物质从水中分离而出。
在废水处理研究中，絮凝沉淀法因其可有效降低废水浊度和色度，能去除多种高分子有机物而被广泛采用。近年来，絮凝剂开发从传统无机絮凝剂发展到无机高分子，有机高分子絮凝剂，目前正在进一步探讨微生物絮凝剂。
2) 吸附法
吸附剂的种类很多，有活性炭、大孔树脂、活性白土、硅藻土等。在有机废水中常用的吸附剂有活性炭和大孔树脂。虽然活性炭具有较高的吸附性，但由于再生困难、费用高而在国内较少使用。
2、 化学处理
化学氧化法分为两大类,一类是在常温常压下利用强氧化剂(如过氧化氢、高锰酸钾、次氯酸盐、臭氧等) 将废水中的有机物氧化成二氧化碳和水;另一类是在高温高压下分解废水中有机物,包括超临界水氧化和湿空气氧化工艺,所用的氧化剂通常为氧气或过氧化氢,一般采用催化剂降低反应条件,加快反应速率。
化学氧化法反应速度快、控制简单,但成本较高,通常难以将难降解的有机物一步氧化到无机物质,而且目前对中间产物的控制的研究较少。该技术也常常作为生化处理的预处理方法使用。 其主要的方法有：
化学氧化法反应速度快、控制简单,但成本较高,通常难以将难降解的有机物一步氧化到无机物质,而且目前对中间产物的控制的研究较少。该技术也常常作为生化处理的预处理方法使用。 其主要的方法有：
1) Fenton 氧化法
Fenton 试剂具有很强的氧化能力，因此Fenton 氧化法在处理废水有机物过程中发挥了巨大的作用。但由于体系中含有大量的Fe2 + 离子，H2O2 的利用率不高,使有机物降解不完全。
2) 臭氧氧化法
臭氧在水处理方面具有氧化能力强,反应速度快,不产生污泥,无二次污染等特点,在去除合成洗涤剂以及降低水中的BOD、COD 等方面都具有特殊的效果。臭氧对难降解有机物的氧化通常是使其环状分子的部分环或长链分子部分断裂,从而使大分子物质变成小分子物质,生成易于生化降解的物质,提高废水的可生化性。
3) 电化学氧化法
电化学氧化又称电化学燃烧,它是在电极表面的电氧化作用下或由电场作用而产生的自由基作用下使有机物氧化。电化学氧化分为直接电化学氧化和间接电化学氧化。直接电化学氧化是使难降解有机物在电极表面发生氧化还原反应。
3、 生物处理技术
生物处理技术是一般有机废水处理系统中最重要的过程之一，是利用微生物，主要是细菌的代谢作用，氧化、分解、吸附废水中可溶性的有机物及部分不溶性有机物，并使其转化为无害的稳定物质从而使水得到净化的技术。在现代的生物技术处理过程中，主要有好氧生物氧化、兼氧生物降解及厌氧消化降解这三类，生物处理技术由于经济可行、无二次污染等特点，已越来越引起重视。
长期以来好氧生物处理技术，尤其是活性污泥法一直是我国污水处理的主体工艺，它具有处理效率高、出水水质好的特点，但它也存在能耗高、运行费用大、剩余污泥产量多等缺点。厌氧生物处理技术因其具有能耗低、污泥产量少的特点，废水厌氧生物处理是环境工程与能源工程中的一项重要技术，是有机废水强有力的处理方法之一。虽然厌氧处理有一些优点，但是厌氧出水很难直接达到排放标准，一般用于高浓度有机污水的前段生物处理，因此后段生物处理仍然必须通过好氧处理才能达到排放标准。
处理工艺选择
综合上述处理介绍，对于生活污水处理工艺优先选择生物处理技术为主要处理工艺，主要原因是生物处理工艺运行费用省，处理效果好。

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;

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.
