Background
A domestic sewage treatment system or a toilet system with zero discharge is a development direction of a toilet revolution, and has the advantages that the ecological environment, especially underground water sources, can be protected from being polluted, meanwhile, the flexible layout can be realized, and very timely and convenient service is provided for people in more critical places and places. In the aspect of building happy rural areas and beautiful rural areas, the novel toilet system is urgently needed to replace the traditional dry toilets and septic tanks, and the natural environment is better protected while the living conditions of villagers are improved.
The prior art treatment means of the toilet sewage has to select a liquid-based form for treatment in consideration of technical problems such as treatment amount, delivery of the toilet sewage, volume of toilet sewage treatment equipment and the like, and the adopted core treatment technical means are classified into: physical precipitation, anaerobic biodegradation, oxygen-enriched biodegradation, facultative biodegradation, membrane physical separation, disinfection and sludge backflow; whether it is an activated sludge process, a biofilm process, a biological rotating wheel, an oxidation ditch, AO, A2O, MBR or a septic tank, are all in the general category of the core treatment technology means. The above technical solution has the following common features:
(1) The equipment volume is very large (the volume is small, the treatment capacity cannot meet the requirement, and the impact resistance of microbial ecology is reduced due to the small volume);
(2) The microbial ecosystem requires special, differentiated and stable peripheral conditions to maintain efficient and sustainable working performance of the microbes; these peripheral conditions include the pair: differential control of temperature, pH value, dissolved oxygen, salt concentration, biotoxicity, carbon source, nitrogen source and phosphorus source (different microbial species are suitable for different peripheral conditions) and stability control (sudden change or impact of peripheral conditions, such as sudden decrease or sudden swell of dissolved oxygen, can cause the microorganism to be "cold and sick", thereby bringing about system collapse;
(3) Starting of a microbial ecosystem, whether the microbial ecosystem is started for the first time or is started after system breakdown is treated, the starting needs to take time of day as a calculation unit;
(4) A stable supply of sewage source (microbial food) is required (if the sewage source is intermittent, say often with several days or months off-supply, the microbial ecosystem collapses and a lengthy system restart is required;
(5) In order to reduce the impact of environmental factors on the microbial ecosystem to the maximum extent, designers generally buffer and dilute the sewage source according to the design specifications of the prior art, and generally, the concentration of sewage (such as COD and ammonia nitrogen) entering the microbial system is lower than that of the sewage source. This means that the entire set of biochemical processing systems will have many different, bulky modules. Even the simplest septic tank is buried, the volume of the septic tank needs to be enlarged according to the amount of sewage.
(6) The unit energy consumption of the sewage treatment amount is generally lower than that of a system adopting a non-biological method;
(7) And the discharge index (especially ammonia nitrogen) of sewage is difficult to be very low, and the best condition can only reach the first-level discharge standard but not reach the standard of domestic water.
In conclusion, the disadvantages of the biodegradation type toilet wastewater treatment apparatus are: the equipment has large volume, poor impact resistance and higher control requirement on the peripheral environment, and the treatment effect can only reach the common level.
Most of the toilet sewage is water (flushing water + urine), wherein, about: 95% of water, 1% of urea and trace ammonia, uric acid, creatinine, sodium salt, potassium salt, carbonate, biological enzyme and the like. Some antibiotics may also be present in urine due to their widespread use (even abuse). Among these substances, urea, ammonia, organic acids, biological enzymes and antibiotics are required to be treated; among the substances to be treated, urea, ammonia and antibiotics are difficult to treat. Traditional biodegradation methods require staged treatment of urea and ammonia, whereas antibiotics cannot.
